Harley Davidson Evolution Motor Disassembly, Part 3

[@splattered2929]

I'm 55yrs now. Have a '94 evo. It was men like you that tsught me so much. Calm, even keeled, smart and kind with a likeable way.

You funny. I'm afraid to watch me.

[@jamescoffin640]

Hi Mike.. where are you located? I was just wondering. I’ve acquired a few motorcycles and could really use your help. A ‘54 k model, an xrt 750, a ‘90 Fxrt with a 1340 and also a s and s motor, and last bit not least a xrtt. All bikes need to be assembled. The Fxrt is about 30 percent assembled.. your videos are great and very informative! They help a ton! Thanks man

Hey Mike. Your probably gonna get tired of hearing from me but i just can't get enough of your videos! After a long day of dealing with people that when u first meet em they already have an attitude and it takes about 15 minutes before I get em laughing and put em at ease, after doing that 10 times a.day it starts to wear on me, but since i found your channel and started watching your videos I instantly forget about the folks that are sometimes complete a-holes not all of em are a-holes.but some are! I really appreciate what u do and I felt it necessary to tell u that. I also want u to know that someome, me, who knows nothing about 2 wheelers, plenty of experience with 4 wheelers but not 2, and after being willed enough parts to build 2 bikes including a couple straight leg frames 2 delkron shovelhead motors trannys wheels bars triples forks all sorts of stuff which I was gonna sell off piece by piece. Since I found your channel and started watching you've inspired me to build one and "get in the wimd" I felt it necessary to tell u that too. My motors are shovels but I came here to look at the differences between the two. Anyway thanks Mike this is just what I needed in my life right now. Do u have a website or an email address, some way to send u some pics of what I have and maybe get some advice on what direction I should go? Thanks again dude your the best!

[@pacificmike9501]

Generally, contacting through the comment section is how I connect with people for now. You know I have a kind of corny belief. I believe most people are basically good. I believe it because it enables me to live in a world of chaos. But, I've always been this way. I need it. I worked in a K-Mart store back in the early seventies. I learned more about dealing with the public there than anywhere. We're all just people, hopefully learning our way through life. Thank You, and Enjoy the Holidays!

Great Video Mike. I feel like we all lucked out with this motor. I know most of the Motors i find and eventually give in and buy have been stored Outdoors or other rough locations .

[@pacificmike9501]

I think you already realize staying on top of those "minor" things will help prevent having to do major things very often. And, it's sure more fun to ride when you become familiar with your bike. Wish I could cruise around Europe on my Harley. Thank you.

[@toolmaker5150]

Great videos Mike ! I am not sure what you are prying on to remove that pump drive gear. It has been a while since I had my Evo motor apart, but as I remember after the pump is removed the long shaft will pull right out , leaving the gear at the bottom of the case. I was always taught by my dad, screwdrivers are for removing screws. It’s not a pry bar. Thanks again for the great video.

[@pacificmike9501]

Tell your dad, I apologize. And, that oil pump shaft was bent and had to be replaced. It had already been replaced by a mechanic who replaced it with a factory defective part. Believe it or not.

Hello Mike I really enjoy your channel. Just bought my first EVO , a 1985 FXR Low and would like to know what would be the best repair manual to purchase. Thanks and always looking forward to your next vid.

[@pacificmike9501]

Harley Davidson's Service Manual for a 1985 FXR. If the dealer can't get you one, try V-Twin (Tedd Cycle).

[@sammybrown6730]

Is a pinion gear removal tool needed on evos? Ilit sure did not look like it on this one. I am about to get into the cam chest on my ss v111 to swap the cam and im told I should remove the pinion gear and measure it and the cam with gauge pins. Thanks for the video! Love em!

[@pacificmike9501]

You'll probably be okay, depending on the cam gear you are using. You can probably get away without pulling that gear. But if not, you'll know by the sound when you fire it up.

[@pacificmike9501]

If you do pull the pinion gear, you'll need a proper pinion gear puller.

[@sammybrown6730]

@@pacificmike9501 Thanks so much! it is an S&S cam so I am sure it will line up but I tend to be safe rather than sorry and have to do it twice. I appreciate you getting back to me so fast!

[@Strutzkiski]

hi Mike.I have big issue to remove pinion gear from shaft. I disassemble a S&S Motor Evo. in your cas youn pull easily the pinion gear, in my case inpossible.Hopefully you reply. thanks. I love your videos, i have reworked my complete Shovel engine by your video

[@pacificmike9501]

I don't know what year you have, but there is a "pinion gear puller" available. Most of the aftermarket suppliers carry them.

[@AntonioMartinez-iv3iq]

Nice old Man

[@pacificmike9501]

Thank You.

[@jimpapay2895]

Mike, on my 1985 FXRS there isn't a large nut like what is in your video to unscrew to remove the pinion gear. Mine has two flat side and two rounded side that don't allow for a good wrench to grab onto? Is this a pressed on gear?

[@pacificmike9501]

No, you're describing a nut. It requires a special socket to remove it. I have a homemade one I've had for years. I believe most of the big aftermarket suppliers have that socket under "tools."

[@mr.noneofyourbusiness3234]

So Mike, how do you replace the brass bushing sleeve if it has been damaged ?

[@pacificmike9501]

That is a tough one. I have done it. One must get very creative to carefully remove that bushing, reinstall it, and size it. Removing it is the big trick. Best left up to someone with some serious machining experience.

[@brianbiggs3484]

👍👍🇨🇦✌️🇨🇦✌️🇨🇦 Awesome videos !!!!

[@pacificmike9501]

[@williamroy91]

I have a 97 roadking would I have to remove the motor to do a base gasket replacement?

[@pacificmike9501]

Not at all. The top end can be removed with the engine still in place. Everything is critical. Make sure of all torque values.

[@henryreich1892]

Thanks for the video was hoping to see the rebuild and inner primary mounting is that in thd cards?

[@pacificmike9501]

When the tools needed get here, we'll finish the motor. When the motor is done, it goes back to my friend for him to reinstall. The inner primary installation varies with how the engine and trans are mounted. We'll eventually show them as they come up. Thank you.

[@henryreich1892]

@@pacificmike9501 thank you ill be looking forward to it got an 1988 fxst i been working on got stuck with the inner primary installation process

[@pacificmike9501]

It's roughly the same as Shovelhead. But, with the Softail, you've got the oil tank to deal with. Makes it hard to get to the starter. Follow the manual, but, with some long "snakey" tool combinations, you can loosen the tank and raise it enough to R&R the starter. It's not easy, but can be done. Take it slow.

[@fernandoantonio5490]

Fabulous Videos! How did you crack the nut on the crank shaft?

[@pacificmike9501]

Air impact. Thank you.

[@bennyjones1597]

I do have a question for you I want to buy a used Harley and I love Road Kings what year and what model would you give a good recommendation for thank you looking for your answer soon and I love your videos they're so great I watch all of them

[@pacificmike9501]

Thank you. Tough call. Do you want an Evo, or a Twin Cam? Maybe you want a new one. How much money can you spend? These are the factors for you to consider.

[@hedonisticpunkvatos]

Great vids. Any vids on just the specialized tools needed when beginning a project? or how to mod a tool? or what every DIYer should have in their toolbox for working on EVO engines? Thanks! -94' Sportster Hugger 883HUG

You start with basic hand tool. Then, when you need to do something that requires a special tool, you buy it.

That oil pump gear & snap ring are a pair of sods! Haha

[@pacificmike9501]

You know, they did it in 1936, and it worked well enough, they just kept on doing it like that 'til 1999. Fun stuff.

[@deadheadlights]

@@pacificmike9501 it is a good design & i can see why they kept it. Thanks for the great videos! Keep up the good work. Al

[@pacificmike9501]

Yes, I think the old Harley oiling systems are great. Thanks for watching.

[@tennesseesam7697]

Iknow some parts might interchangeable but would the top end of a 2004 and earlier twin cam fit on a 95 thru 98 evo motor i'm mean everything from the barrels on up without modification

[@pacificmike9501]

I don't remember what it took, but, when the twin cam motors first came out, it was done. It didn't take long to find out it wasn't a great idea. The first thing that comes to mind is the difference in bore sizes. After that, it got more difficult. I'm sure it's been done successfully, but don't know what the advantage would be or exactly how much effort it takes. The ones I remember were called the "Fatso Motor."

[@michaeldawson217]

Mike, working on this same motor. I don’t have a cam push driving tool like you used to remove the cam chest cover. Now my cam chest cover is stuck to my cam. How could I remove it? Does that hex head I see need to be removed?

[@michaeldawson217]

I also have some questions about my motor itself.

[@pacificmike9501]

Are you speaking of the bolt into the cam itself? If so, yes, it has to be gently removed. I made that puller to remove the cam cover. Do you have a service manual? Have you backed off the lifters? Do you have a proper, year specific service manual?

[@michaeldawson217]

@@pacificmike9501 no I don’t. I’m not sure what manual I need. It’s a 1997 FLSTC 80in EVO. But it has the “Screaming Eagle” package. I’m not sure what all the screaming eagle package consists of. But yes I pulled the lifters, and I have removed the cam chest cover and everything inside the chest except for the oil pump gear.

Okay. You're in. What is damaged?

[@jeffreyhill7990]

Is it a last resort to split cases? reason I'm asking is, say I want to put new case seals in my shovel?

[@pacificmike9501]

Yep. Hate to take something apart that's functioning well. The only seal is at the output (sprocket shaft) side. After that, the ony major leak would be the case mating surfaces. The cases are split, lapped and then put together with the proper sealant. Then, the endplay of the flywheel assembly must be verified correct. A little "weep" here or there is not a big deal. Once a motor is opened up completely, it's time to get real serious.

[@61espo]

The shaft pulls right out of the pump leaving the gear in the bottom of the case to be removed with your fingers.

[@pacificmike9501]

Unless the shaft, bushing, or both, are damaged by the last guy who was there.

[@Wooley689]

Your videos, Mike, have become my addiction. Foo-pah's like the rest of us and all. Not to be confused with that newer slang term of fupa mind you. What are the measurements of those lifter retaining tools and the cam cover puller if I may ask?

[@BEEBEE159]

Mike, I have heard that the Evolution motor is the best motor that HD ever produced, the original version, which as I understand was produced up until the late 1990's. Firstly, do you agree with that opinion? If so, do you think it would be better to buy a late 1990's Harley Sportster, rather than the newer ones? Note, my main concern is reliability and being easy to work on, as I always maintain and repair my own machines. Thanks.

[@pacificmike9501]

I try not to favor one Harley engine over another. But, I think your choice is excellent.

[@BEEBEE159]

@@pacificmike9501 I see the original Evolution is a 80 c.i. (1340cc) engine, with a gear driven single cam. It doesn't look like that engine ever came on a Sportster. However, I found a 1995 FXD Dyna Superglide that has the original Evolution engine.
