Delboy's Garage, Harley Softail Service #5, 'Full Purge' Oil Change.

[@raymondgarafano8604]

Hello Delboy! I just read your story about how you got into wrenching on bikes. Very Koool! Took a ride on my Sporty came back to house, at a given place I shut off gas do float bowl is empty when Im at my place so gas doesn't sit in carb, she is idling a bit and I see white smoke curling up from front lower left near shifter. It seems like the wires from the stator are very hot. I shut the bike off. it is raining heavily. have you ever heard of the stators plug going bad and shorting out? I guess it is the rectifier/regulator. HD says 19 to 26 volts per 1,000 revs, will check to see if stator got grounded, if it did in 2 places the coils will overheat and burn out. Muswell Hill that u mentioned and other places I have heard of from Rumpole of the bailey, a large cigar smoking barrister with great stories.

[@kanSevar1]

Thanks for all 5 series Softail!

I change 6L of oil in my Fatboy, but the change is dynamic when the engine is running, I have a 100% replacement

[@keithhults8986]

I just did my 1st full purge change. Stock 2002 FSXTDI Deuce 8560 miles. I rode my bike 5300 miles on 2 tank and filter changes. It took me about 2hrs cause finding my filter wrench was a 30min waste. My return line had Oring/hard spacer/Oring. The magnet was clean aside from the normal spec of black dust after 2500 miles. Thank you! Your podcasts are so well edited, even a mechanical idiot can do it! I feel very reassured, knowing for a fact that my engine is wear free and clean inside. I am an endless haunt about clean engines, inside and outside, because I owned and repowered 7 different types of boats over 45+yrs skiing and on open water. There ain't no tow trucks at sea! When the pair of engines under the deck suddenly stop, start paddling! 😂 I have never been towed back to the dock since I stepped on a boat in 1967. Other people's boats for sure, but never mine. Blue Skies and Rubber Down Everyone!

[@Moonfleet41]

Thank you for sharing your kind words buddy.. !

[@edgomez3322]

I just have to say that I watched all five oil changes videos from Delboys Garage and I must say I am very satisfied about all of them. He was very precise and straight forward how each one should be done. Thank You very much for your expertise!!!!

[@gregvidito3383]

Thanks for this. Been using a scavenger system to do this. Has a oil filter bypass to allow you to drain the dirty oil . But your detaiIed info especially on that rubber O ring in the return line hole, didn't know that. Mine been leaking out for years. Awesome. Really glad to have watched your video. Cheers from Nova Scotia!

[@Moonfleet41]

Thanks Greg, glad the tip helped out, it's amazing how the little things can cause problems aye.!

[@John-cc1pc]

Thank you for answering my question about engine flush. Great explanation and reasoning. So good to know why as well as how. You are excellent. Thank you so so much. 😊 Safe rides 👍🤜

[@Moonfleet41]

You're most welcome John. Glad to help, good luck with it. !

[@johnhowell9655]

Awesome video, my friend has told me about how this is how he does his oil changes....I didn't really understand what he meant. I do now and will always be doing my oil changes this way from here on out. Thanks for the great lesson.

[@Moonfleet41]

Glad it helped see the visual buddy, best of luck with your porjects! All the best, Del

[@kentsvensson7009]

It's time for me this week to change engineoil, so i do it with cold engineoil as you do. I trust you to 100%👌🙏👍🤟

[@TheWhitegoldwing]

Could you do a vid on checking & replacing the plastic cam chain tensioners please

[@Ricky-l7x1s]

I just bought a 2003 Springer Softail that has not been run in several years. This video is exactly what I needed to know to purge the oil system.Very informative and easy to follow. Looking forward to checking out more of your videos. Thanks

[@Moonfleet41]

Glad it helped, and welcome aboard.

pretty cool way you go about things delboy. you are certaintly on to it. thanks for thw tips and all the little tricks. love your work.

[@Moonfleet41]

Most welcome buddy, Glad to help!

[@richardmckinley3236]

Very enlightening. The amount of extra dirty oil you got from the purge is an eye-opener for me. Excellently explained as always. Thanks!!

[@Moonfleet41]

Thanks Richard, I thought this would surprise a few people !

[@waltradcliffe4482]

I have a 2005 fatboy didn’t like leaving all that dirty oil when I changed it I liked your idea on purging it read most of the comments to see if anyone else stated this my bike has two o rings and a plastic spacer in-between on the return line so be careful so you don’t lose any of it when disassembling

[@flstf9645]

Fantastic Video's. All of them. I was confused about one thing though. After the 10 revolutions then replacing the oil filter, I noticed the oil level in the tank was not dropping the way I thought it would. I watched you cycle engine, then add oil, cycle, add oil, etc. Basically I was cycling 10 rev's, stopping, cycling 10 more, stopping, etc. Never saw the level in the tank drop until about the 4th or 5th cycle. So my question is, if I'm watching the level in the tank carefully, do I really need to stop at 10 rev's to add more or can I keep cycling until I see the level drop? Thanks again for these Video's!

[@andrewrobertson9103]

I am absolutely gobstruck. I have been paying for regular servicing and I don't believe they have ever done this, probably because I didn't ask them to purge ALL the oil. I love this video, it has added to my knowledge so thank you. I will be watching all your other videos now.

[@Moonfleet41]

Most welcome, glad it helped you.

[@Jasongoesfast]

Just purchased a 2009 softail off my brother, He recommended that I watch this series on servicing as he knows I'm too frugal to take the bike to a stealership, Thanks for your great information I'm glad I followed my bros recommendation. Top job!

[@Moonfleet41]

Thanks Ando's, am glad you could find the series useful and good on your for taking this servicing on yourself, it expands the pride of ownership and puts you better in touch with your bike... good luck with your projects and have fun!

[@lenyfi1652]

I am a retired mechanical engineer, new to biking and soft tail Harely, love your videos,very informative please make some more. Thank you .L..f.

[@Anagaw1]

You are the best mechanic ever.

[@petesquickfixdiyshortautor1218]

At the 14 minute mark you talk about the O-ring going in the tank and then getting sucked though the oil system. Wouldn't there be a screen and or a filter to keep things from getting sucked up into the lubricating system? I know we don't want to plug up the screen so it's best to find it, but I don't think it will go very far. Great videos. Aloha

[@Moonfleet41]

Not to my knowledge Pete, the outlet hole in the tank is straight through and I imagine the first filter it would meet is the actual oil filter, but it probably wouldn't get that far as a rubber O-ring would wedge in an oil way long before that then impede flow.

[@barelyhuman8391]

just did my 1st oil change with a dude i met who was willing to show me what to do we didn't do this but i will the next change ty for the great info man much appreciated

[@Patrick_B687-3]

Two years on and about to do my fourth service, I still haven’t done the full purge, although I don’t argue it’s better. I’ve never wanted to risk losing or breaking the fitting parts, but I might actually have a go at it this time. What’s funny however, is not having found one technician, or DIYer who even knows about this, and I’ve asked a bunch of people. What’s important however, is your videos more than any others inspired me to do all this work myself, and I’ve learned so much. Everything in this series of 5 is so, so easy, and my bike is in tip top maintenance wise all the time. Thank you for making these and making it look as easy as it is.

[@Moonfleet41]

Most welcome indeed Patrick, and im very proud the our videos have been such an inspiration in keeping your bike in top condition. It's not critical that you purge the old oil out, but as you can see there is a fair bit left behind with the dry sump system on the Softails, and ive found over the following miles after the purge change that the new oil stays cleaner for longer, which naturally means it is less contaminated with old oil.. Who knows why the Dealers don't bother to support the practice, im not really interested as to why, im just looking at my oil, and using common sense to make sure its as clean and free from the old sump oil as possible.. Ride safe my friend, and thank you for your support .

[@mickthemerciless9694]

Don't be afraid of getting to know your bike. It's another level of satisfaction.

[@bruceburns1672]

I would have never known this until this video , I always thought that what I was doing just draining the tank was a complete new oil change , thanks for this .

[@allowambeBOWWAMB]

This is an excellent tutorial. So no need for a hot engine, then. There was something about particles being suspended in hot oil that has been running for a bit. But I guess that's also purged out here. I actually got replacement upper oil retainers just in case. I might as well replace them!

[@phdzzz]

Thank you so very much Delboy, now I know where all the dirty oil came from, when I draint the crankcase, (the plug under the engine in the middle) Your way of changing oil is, in my opinion the only wright way. I found the plug accidentally, and when I got it out, there came more than a liter out of the engine (after the 'normal' oil change)

[@willhogue8575]

Just completed the oil change and purge following Delboys excellent instructions. Thankyou Delboy, my 2009 Fat Boy is now running on clean oil and filter.

[@garyfitzgerald9653]

I just finished purging the oil on my 14 Softail Deluxe. Pretty easy following Delboy's step by step. Thanks

[@John-cc1pc]

An excellent series. What a great idea of breaking it all down. Awesome info. Accurate easy to follow and concise. You are a true gent! Is there a way of purging oil from a twin cam and M8 please? Keep it up 😊 Cheers John 👍🤜

[@Moonfleet41]

Hi there John.. this bike was a Twin Cam.. and the purge is only relevant on the old model Softails with dry sump and oil tank.. it's to purge the external oil lines which gravity can't drain... but the M8's don't have them, so no need mate. !

[@TheSwiftie]

Thank you!! What a huge difference purging makes. My oil is cyrstal clear!! Thanks Delboy!!

[@Moonfleet41]

You are so welcome

[@DrTee_Chanthaburi]

Good job

[@harrymontague3237]

Excellent video! Did a purge on my 2001 Heritage Softail Classic and what a surprise. All that old oil that would have been left behind at any dealership. I will be watching all your videos. You have that straight forward approach that just makes sense. Thanks!

[@Moonfleet41]

Thanks buddy, you're very kind, there isn't actually that much dirty oil left in the engine, if you were to scrape out the dirty oil in some way, it'd probably be less than half a cupful, but when you get almost 1.5pints of dirty oil out, much of that is actually new oil that's rinsed the linings of the oil ways and all the hoses and cleaned them, like a detergent, so you are sacrificing, maybe, a pint of your new oil to wash out the old stuff, but as you no doubt agree, it is so worth it... your new oil will stay clean for at least 1000miles before it even begins to discolour so the next purge you do will run clear in, maybe, half a pint... thanks again, ride safe, Del

[@Beeza56]

Thanks Del, just bought a ‘14 Fatboy Lo and will be doing a 3 hole as soon as I get it home. Hope all’s well with you too. You’ve been a boon to me over the last few years as I have an 865 Thruxton (with Meteor chair) too. All the best from Putnam Valley NY.

[@Moonfleet41]

Congratulations on the new bike Ian, ive had one of those and they're awesome.. good call doing the oils, you never know what previous owners have done (or not done), Hope it's not too cold over there for you yet, we know you get snow pretty bad in winter, so keep safe and warm.. all the best..

[@VintageRider]

Thanks for sharing your knowledge with us! Congratulations for the channel and the new garage! As a mechanic, your videos are helping me a lot here in Brazil in order to provide a better service to my customers.

[@Moonfleet41]

Hey Marcelo, so good to hear from you - it makes us very proud indeed, that our videos can reach out to the 'trade' and help the professional side of the bike mechanic world...

[@lassei4659]

Nice tutorial! A tips, When installing a new filter, slightly moisten the sealing edge in the filter with new oil to be sure a rubber surface isn't torqued towards a metal surface, it can cause the rubber seal to do unwanted flexing. And thx for great process videos!!!

[@mikeheckman4995]

Thanks for being thorough. Changed many oils, but first time for Twin Cam. Very simple thanks to you! Purged well over a quart of the old stuff (Syn3). The only suggestion that I have is to try 100% synthetic. I used Amsoil and am very impressed with results. Engine runs quieter and shifts smoother. Thanks again mate, and CHEERS from South Carolina, USA.

[@wmcwane01]

[@Moonfleet41]

Very welcome

[@peterfox6447]

Great explanation on all your videos. Blown away with your video on a full engine service, I feel like I’ve been deceived by Harley Davidson service agents when running old dirty oil or not through my new clean filter.

[@Moonfleet41]

Hi Peter, please don't take a downer on the dealers, they're doing nothing wrong, the factory doesn't stipulate that you must purge a Softail engine as the 5k oil change interval is probably more than it needs to be, you can push them to 10k in the right climate and it won't hurt them, they're a very robust engine, but purging is just a purist practice to make sure you've removed all oil and I'm sure if you asked your Harley dealer to do this for you, any technician would be happy to oblige, and probably wouldn't charge you any more money... all the Harley techs I've ever met have been dedicated enthusiasts and bikers just like us, and they care about what they do.

[@peterfox6447]

Hey Del, Can’t believe you got back to me so quickly, thank you. I didn’t want to sound out HD like I did, they have been really good to me in the past, sending a text can be taken in the wrong light sometimes. I have a 2006 Fatboy 88 FLSTFI only done 19,300 Klms, do I need to worry about OIL Pressure Mods at this stage? I am looking into filter options ie vapor hoses from top end covers being redirected into Catch Can/filter instead of going directly into intake manifold. What’s your take on these mods? Do you have any videos on these subjects? I’ve got hundreds of questions to put to you but these will do for now. Cheers Peter

[@Moonfleet41]

@@peterfox6447 Breather hoses are directed in to your air box, so that the fumes and vapour can be re-burned through the engine, and then cleaned by the cat convertor, it's designed for the control of emissions, unless you've tuned your engine to create more power, you don't need to open up the breathers to run more freely, they're perfectly adequate as standard, and running them in to a catch tank is to prevent any oil drips or spray making it the road... but it serves no purpose other than that... just make sure your air box is clean and free from any oil build up and that your breather hoses are free flowing and not kinked or blocked.

Hi Joe, thanks for watching mate, am glad the video helped, enjoy your projects!

I had oil spilling on my exhaust from what I think is the oil return line, it’s the same one you took out from oil tank. I was wondering what js the size or part number of the o ring that goes with the plastic release thing. Thank you

[@tonysellen7419]

Hi Del just finished doing this oil change, i followed all your instructions, the only problem i came across was removing the oil filter, there was no room to get your hands in and the same person must have done it up that did the clutch jam nut up, so it was a quick drive over to the dealership to purchase the filter removing tool (£12 not to bad) so that i could finish the job. thanks again as now through your videos i have done a complete oil change on my bike, look forward to the fork oil video to expand my knowledge.

So after first initial purge change oil filter then start the drain process 10 evolutions and then keep filling it up till you run clean oil out clear hose?

What a fantastic video..I had no idea I was leaving so much dirty oil in the engine. Without a doubt the best series for Harley Softail oil change maintenance. Thank you to you and you lovely camera woman .

[@Moonfleet41]

Thanks buddy.... It is surprising how much is left behind aye... many disregard the procedure thinking its just a small splash left behind... but they change their tune when they realise its almost a litre... Thanks for your kind comments mate.

[@Mark-xs7st]

I cant believe the harley owners manual mentions nothing of this purge procedure. Excellent video. Thanks for the enlightenment. Almost a third of the oil is left behind otherwise.

[@jameslanning8405]

Great info on the oil purge... I almost never trust a dealership to do anything if it isn't profitable to them... So purging the oil would be a loss to them, if the oil change is a fixed price, and not based on doing anything right.

[@ck-wm9zx]

Hi Del, eXcellent video that inspired me to purge the oil on my sportster 48. On a sportster things are a little different. The oil return hose is below the oil level, so if you pull it you will make a mess. I prepared a spare hose and suspended one end higher than the oil tank and connected it to the return of the tank. The oil-tank is made of plastic, you must be very careful when removing the clamp. The sportster has a weaker battery which has not enough capacity for cranking the engine when flushing the oil that collects in the sump so I ended up using the power of the engine. Fill the new oil filter with oil. I was very careful not to run out of oil, watched the oil level and the oil pressure light. I topped up the oil tank and flushed one liter until fresh oil apeared, which leaves about 1.5 liters in the oil tank. All other procedures were the same as in your video. Thanks for your great videos.

[@Moonfleet41]

Oh my goodness, I wished you had asked buddy - you don't do this to Sportsters! Mainly because you can't return the oil properly and there is only a fraction of the oil left in the system anyway, you may have run a litre through it, but the pipework on a Sportster holds barely a cupful of oil, if that... I wouldn't do this again my friend, a) because it's not necessary, and b) if you break that outlet pipe off the tank, they are about £200... ! Glad you got away with it, but I wouldn't prod that dog again mate...

[@ck-wm9zx]

Moonfleet41 you're right there's only one cup of oil in the hoses. Breaking off the outlet pipe from the oil tank would have made up an excuse for fabricating a custom one ;-), now the return line has a removable clamp. One cup of oil stays in the sump which is located below the level of the oil pump. Another cup drips down from the rocker boxes and timing gears. 3.6 us quarts (3.4l) of oil in the system of which only 2.6l get changed. This was a part of the 20k mile service I did for the bike.

[@robertfindley4312]

[@rizzo3689]

You are the man! Just picked up my first Harley...2005 Deuce. I get itchy if I’m not wrenching on something. I’ve always done my own maintenance. Stoked that I found your vids. They cover everything! Rare to find this level of attention to detail these days. I am always a fan of a full oil change. Never understood why people would change their oil with a simple drain and fill. Really just mixes some new oil with some old resulting in a minimal increase in protection. Thanks for helping us yanks out on this side of the pond!

[@Moonfleet41]

Thank you brother, you're dead right on the purge change, at least a pint of the old oil never comes out, and that shortens the life of the new oil, not an issue on Dynas, but on the Softails it's a great practice... glad to be of service Sir, stay tuned and keep in touch, we think you will rather like hte next project to be revealed this weekend!

[@ericdrozdek2901]

I was hesitant about doing it. I did it another 24oz of oil came out so thank you very much. I hope everyone at least does it once in a while by turning on the engine both drain plugs open the oil plug and the filter plug was open, and it was draining at the same time, hope this helps. I’m not a professional. I took his advice and I’m glad I did.

[@tssci6774]

Great video, modern engine with overhead cams, VVT, turbos, coolers, etc in your cage can also retain up to a quart of oil after a normal drain and refill. That remaining oil will contaminate the new oil, and increase wear, reduce viscosity and increase oxidation, varnish and sludge. Perform a second oil change after running 15 minutes and get a 99% fluid exchange in most cases. Then use the same oil for the next flush or use it in your grocery getter. WIth a full sump of clean oil, it can now do its job much better in protecting and cleaning your engine.

[@haroldwiser2641]

[@bm7760]

Enjoyed this series for the Softail. Thank you. Wouldn't read too much into the lack of metal on the drain plug magnet. Its location isn't really ideal for picking up particles. I put neodymium magnets on my filter. That's much more effective. Thanks again.

[@patrickzambori473]

your plug wires need to be grounded when cranking to prevent risk of over voltage damage to the ignition coils. You can also unplug the coil. Best practice is to remove the spark plugs to ease the starter and driveline when cranking with zero oil pressure.

[@MikeTomillo]

My only quibble with this is unnecessary decoupling of the spark plugs. It is simpler and faster to just engage the kill switch before cranking it. No spark is going to the plugs.

[@patrickzambori473]

@@MikeTomillo Typically, the engine will not crank from the handlebar switch with the run/stop in the stop position. I will typically jump power to the starter solenoid directly if I don't want the ignition system or fuel pump doing anything when cranking.

[@allowambeBOWWAMB]

Are you sure it does damage to the ignition coils?

Glad I seen this video.I got taken for a fool from a shop and had been friends with them for years.Took my bike in thinking it was low.I watched the machanic just drain the motor oil.Then put in 60w oil didn't even change the filter.Charged me 158.79.That really bothers me.Iv done tons of work for them and not charged a single penny.I rode my Deuse back to the house less than a 8th of a mile from their shop to my house.Will never let them even touch my bike again.Its a 2005 model and only has 10400 miles.And to put the cherry on top.The mechanic dropped a wrench on the rear fender and now has 2 quarter size gouged marks thru the paint.Not at anytime did he say so sorry or offered to have it fixed.To say I was ticked off is a understatement.Had I not have back issues from a 18ft fall in 06 I'd would have not taken my baby to anyone.

[@Moonfleet41]

Hi Robert, im so sorry to hear that sad story.. to have your faith in professionals tainted in that way is tragic.. There are a million, well trained, conscientious and hard working technicians / mechanics out there struggling to make a living for a blue collar wage.! and guys like you describe here, they let them all down.. it's no different to a bad chef or a bad cop.. there are always gonna be rotten apples. But don't lose faith in professionals buddy, they ain't all bad, and i know when i ran a bike shop we always worked hard to maintain a good reputation. Often the bad guy is the fat-cat CEO who charges $158 for an hours work then pays the technician $20 an hour... you won't see many mechanics with a big house and a Lexus! Keeping your bike maintained yourself is not just peace of mind, but a good way to expand the pride of ownership and have a better faith and confidence in your bike day to day, but for those harder jobs that you can't tackle, try to find a local mechanic you can trust, and if you do.. then spread the word and support them, because they need the support, it aoint a well paid job that's for sure.. Cheers buddy and take care.. Del.

Del, wow!...just looking into softail maintenance and I’m so glad i bumped into your video. I have a 21 Street Bob arriving at the end of the month and I’m really looking forward to tinkering. I normally change the oil in my other few bikes between dealer services because i just do and ive never thought about purging.....astonishing how much soup is still sitting in the engine. You may not get this comment as its 4 years ago you broadcasted. If you do many many thanks for such an important well made video. Kind regards Beans.

[@Moonfleet41]

Whats That?.. a Brand New Street Bob coming this month?.. CONGRATULATIONS Brother.... Welcome to the Dark Side ! and the good news is.. that "purging" only a[[lies to the older Softail models because they are 'dry-sump' and have a separate oil tank...the purge process flushes out the oil trapped in the motor and delivery pipes... but your new Dynatail Harley has a regular Wet-eump design with a sump plug under the engine, so when you take the plug out, ALL the oil comes out, just let it drain out, replace the plug, and refill.. Take care and have lots of fun with the new Pony.!

The purge, if thoroughly done, will see your oil clean for about 1,000 miles, but if you've already put 3 litres in, it's whether you want to waste that or not!

[@marcshaner3658]

Prior to performing my all fluids service, I installed an HD Oil Cooler kit, will this procedure purge that system as well? I’m hoping this is a not a dumb question as the oil cooler system doesn’t open until it thermostatically reaches 185*F. Thank you for your time.

[@Moonfleet41]

@@marcshaner3658 I'm not sure how your system is plumbed in Marc, usually it would become an integral part of the oil flow system and you'll purge that too, but if it does have a thermostatic valve, then you would need to drain it manually so that ti refills with the new oil..!

[@marcshaner3658]

@@Moonfleet41 The oil cooler is a Harley-Davidson product, it has a flange that attaches to the factory oil filter mount (which then the filter attaches to that) then supply and return lines that run through the actual cooler. I suspected the answer that you gave me. Obviously doable, but seems like a pain in the a#%. I don’t think it’s a great idea connecting and disconnecting these oil lines every time I do a service. But I can see there’s probably no way around it. Thanks again for your reply.

[@marcshaner3658]

May I bother with one more question? I have a 2006 Fatboy and I did find a threaded plug at the bottom of the oil pan (?) or case bottom (?). It is removable with a hex socket. Wouldn’t that drain more oil than just the plug in the frame? Again, thanks for your time.

Awesome series!! Its a great feeling that these 5 video's will be available for review as many times as needed to do a proper servicing!! Thanks again!!

Watching this for the second time ,well numerous reasons anyway my dad was very good harley wrench unfortunately passed away in 06 he would always show me the right way of doing shit on motorcycles you are very good like he was. Anyway I subscribed and have been showing all my buddies w softtails your video why the manual doesn't tell you how to change it like you do is beyond me anyway keep up the good work mate from ft Collins, colorado

[@Moonfleet41]

Hi Stephen, good to hear from you, sorry to hear of your Father's passing, it sounds like he was your mentor as well, and it's good that you kept those lessons and use them in your life... thank you for subscribing and welcome aboard Sir!

watched tour videos on how to work on my sportster years ago.I sold it and just got my H-D softail deluxe and had to find you! Glad you are still doing the vids done the full service myself thanks to you keep them coming would love to see a vid on cam swaps and such. thank again🍻

I will do the 5000 mile oil changes myself then, I told them that when I saw them last. Purging is one of the best things I've seen in ages, amazing how much more dirty oil you got out 👍😎

[@cela6280]

My first bike 2016 Fatboy S and will be changing the oil of my bike this weekend with more confident. Thank you .

[@cyrilkeane6403]

Did the oil change on my softail today. Tried to follow your instructions but ran into some problems. Bike has been stood for a long time unused. No oil registered on the dipstick on the jiffy. So i fired the engine up briefly and then see oil register on the dipstick. Proceeded to drain the oil and follow your instructions. Problem is after installation of the new filter, turn the engine over, oil comes out the return pipe but the oil level in the tank stays constant. Topped it up again and turned the engine over until no more oil comes out the return pipe, oil tank still fairly full.At this point I decided to go no further, any idea what has happened?

[@williebutler9576]

Thanks 👍

[@rsbharley4766]

Brilliant series Del and Penny, there would not be many people know about that extra bit of oil in the motor and that it needs to come out. A lot of my mates didn't This video will help lots of people for a lot of years to come, job well done.

Do you have the 1340 Evolution in your FXSTC? If so, how much oil did you use for the engine flush/change? I have a 1997 FLSTC

[@stevenleonard7219]

I did my gearbox oil change out of necessity. My clutch cable snapped! I changed my primary oil also out of necessity. Had a minor accident that caused a hairline crack in primary cover. Fixed it with small amount of J B weld. I've only recently found your channel, recommended because I subscribe to Ryan Urlacher's Law Abiding Biker. Your channel is very interesting and informative. I now subscribe to your channel and will send financial support when I can

Great video. What size is that plastic hose you're using on the oil return line?

Try 6mm ID (1/4"), that should do the job.

Another excellent guide Del and Penny, never done this in the pass and I have just changed the oil on my Sportster couple weeks ago but I will in the future thanks for the guide.

[@Moonfleet41]

Ayup Dean, good to meet you t'other day - you don't need to do this on a Sporty - not only is there a fraction of the oil left over compared to Softails, also your return hose is permanently clipped on... just change the tank as prescribed!

[@deanchild9848]

OK tip taken Thanks Del and yes was really good to meet you both on Sunday.

[@juleshall28]

Hi Del Just a news update on the Fat boy service. Engine oil purge and change proved a challenge. 1. Oil inlet pipe into the oil tank did not want to come out. Pinch clip broke but replacement found and refitted. Oil filter did not want to come off, after many different attempts it finally freed up with a clamp at the thread end of the filter to finally free it up The inlet oil pipe did not go in easily it had pinged out and was sitting above the inlet tank hole!!!!! Finally got it in but after much fiddling and squeezing. Next , clutch and drive chain adjustments.....have to wait until Sunday. Jules and drive chain adjustm ed nt

[@Moonfleet41]

Good luck with the jobs on Sunday Jules, hope it goes well !

[@juleshall28]

@@Moonfleet41 Thanks Del. Clutch and primary drive chain adjustments tomorrow.. How are you doing?

[@GaryLordsWayMinistry]

If you change your oil filter more the oil should never get dirty at all and only need to be topped off from time to time. That is what we did on engines in the oil fields that never shut down for oil changes. Just plumed a bypass on the engine oil to change the filter, replace it and open the valve back up to the filter and let her run continuously and never lost one engine due to lubrication problems, many of those oil Cat motors are still in operations as well, 20-40 years later.

[@johnc.holmes4513]

wow, that's a lot of dirty oil. I used to change oil in my Road runner when I was a teenager, run it a bit, then change it again, I thought it would help, same conceot. Great info

I admire your attention to detail, I have a 1999 softail heritage EVO, need to do a 3hole fluid change with purged old oil, is the process the same for an older softail.

[@Moonfleet41]

As long as you have the return pipe system on your Softail then yep, it's all the same... just make sure you identify the return pipe correctly in case they're arranged differently on the EVO.

Not at all. I salute you and would do the same if could in my twin cam. Dels and Penny videos are awesome- what an inspiring guy.

[@beri232]

I’ve read mixed reviews on this on the forums. Some guys say they only get 2 ounces of dirty oil when purging for an oil change. Others say they are able to get almost an entire quart of dirty oil out. I am swapping out regular old dino oil for full synthetic Red Line so I plan on purging my bike as best I can to avoid cross contamination. I find working on my bike is therapeutic so I don’t mind spending the extra time. I almost bought that Scavenger puck kit but I’m going to save myself $100 USD and do this method instead.

RAIDER69 lol no argument here either bud, just pointing out at the very beginning of the video he removes 2 spark plugs from the clutch side of the engine as well as in a previous video when he was adjusting the tension of the chain case and was free spinning the rear wheel and put it in 4th gear.

RAIDER69 it was quick and right at the beginning honestly if I didn’t watch it twice I would have missed it as well but there’s a lot of crazy mechanics out there making videos but this guy is good very through although he says checking the oil on its jiffy stand is the way to go but my service manual I read it should be done at operating temp with “ a helper holding it up straight while checking oil level on trans and motor oil.
