Second time watching, great info. What is the hose coming off the engine for? Was the breather on the left side on Panheads? 11:47

The breather originally huffed it's air (and a positive drip oil system) into the primary chaincase. Now running a primary belt drive, so the drip is turned off and the breather hose has been rerouted out from behind the inner primary cover.

[@tomclark6271]

Harleys are kinda like airplanes, they're designed to leak some, otherwise how you supposed to know when to add more oil? If it's not leaking, you're out of oil.

[@DanWhitehead]

Hi mike im doing the seal but my trans is a 78. I didn’t realise the spacer from 77 to 79 is different in that it doesn’t have the locking tab until I took mine apart. The replacement spacer I purchased has the notch in it and locking tab, is it ok to use this and instal the locking tab. I can’t find the 77 79 spacer in stock anywhere and would have to get it shipped from overseas and probably pay more in shipping then the part is worth.

[@pacificmike9501]

I understand. But they actually fit differently. You need to use the correct seal and spacer. I used to go through it with my 77. Then, I installed a Baker 6 speed. Harley made some changes in the seventies that were rather confusing. They still do constant changes and you have to be very explicit when sourcing parts.

[@DanWhitehead]

@@pacificmike9501 appreciate the response Mike. I’ve bit the bullet on the shipping cost and ordered the correct part. I’d rather wait a few weeks for it to arrive and go down the road knowing I did the job right.

Hi Mike I got a 1996 evo And I can't get the clutch basket off do I need to use a puller on it? Thank you for your videos there great

[@pacificmike9501]

It should slide off with the hub. It is on splines. If it is stuck, you may need a puller. If so, be very gentle. It should slide off as one piece.

[@75hdfxe]

Nice work! Did the original spacer have the key to lock it into the splines? Can you just retrofit with a later model spacer? I have a "75 and wouldn't mind getting rid of the key, I think it might seal better without the gap on the spacer for the key.

Disregard, I should have waited until the end of the video before I asked.

[@tommydemis9094]

Hi Mike, another great video, I am doing this right now to my 76 FLH.... I hate to nit pick, but I have too... I'm sorry.... but I noticed when you removed the old parts the seal came out first followed by the cork and then the spacer... when you put it all back together, you inserted the cork first, and then the spacer which was inside the seal.... I am confused now, my manual seems to indicate that the way to re-assemble is the way you originally removed all the parts.... i.e. spacer, cork, and finally the seal... Please advise... I love your videos and you are my go to source for how to fix my bike... thanx in advance!!! Tommy D.

[@pacificmike9501]

Thank you. I don't think the factory would argue this one. The cork goes in first. You'll find it easier to place the spacer into the seal and then press the seal into the case with the spacer already centered. Just my opinion, but I think you'll like it.

Hi Mike.. Panhead here from the pinelands of South Jersey I'm also a bike mechanic I got a 58 pan and I'm going to put a belt primary like yours I need to shut the chain oiler off with the screw turned in does some oil still come out because I seen you have a hose coming from the chain oiler running along frame do you have it just dumping onto the ground or do you have it running onto your drive chain ... Mike I came across your videos today really good videos I am also a old school mechanic you do really good work I come across tuff seals can I put my two cents in before start drilling I put a dab of grease on the drill bit keeps the shavings and filings in order out of your case keep up the awesome videos bro

[@pacificmike9501]

Cool. Thank you. That tube is the breather for the engine. Turning off the screw to the oiler, stops the oil. But, the engine has to breathe. Oil from the engine will come out of the hose in a slight mist. Hence, the hose needs to be routed out of the primary. If the engine ever wet sumps, the hose must be routed to the great outdoors.

That is a Police generator and the condenser is for static elimination on the radio. You need a Harley Davidson Factory Service Manual. It has full instructions and diagrams. Tedd Cycle (V-Twin) should have it for you. All of the aftermarket shops deal with them. Or, you could find it online.

[@donsmith5534]

Mike, the attachment or end of the slide hammer that screws into the seal, is that homemade? I'm thinking that's a bearing slide hammer. also any tips on removing the engine sprocket seal on a 58FL. like always, the most informative videos, thx

[@pacificmike9501]

That screw attachment came with the slidehammer as part of the set. It is a Snap-On slidehammer. I've had it for at least thirty years.58 sprocket shaft seal is a screw in and check your service manual. Probably the 59-69 service manual would be your best bet. I haven't done one of those in quite a while. But, it screws in. 55-68 is when that particular seal was used. Buy a Colony unit. And, you're more than welcome.

[@MrXYZ-uv4gj]

What direction did you place the double lip seal onto the transmission? With the grooves in or out? They're not actually grooves in the seal but appear to have curved lines on one side and a lip facing out on the other side. I couldn't see which direction from your video and there is another youtuber out there who shows the seal to go in with the grooves facing towards the outside. Thanks.

[@pacificmike9501]

This is a 37-76 type trans. The seal is shrouded in sheet metal. If it is a faithful copy of the original seal, then the metal is made of two pieces and the seam goes toward the trans. If it is a later copy of the seal, one side is open and goes toward the trans. If you're lucky, you have a "Genuine James" sesl which is a faithful copy of the original (which was produced by Chicago Rawhide).

[@MrXYZ-uv4gj]

@@pacificmike9501 Thanks Mike. I realize the explanation of the direction of the seal is hard to replicate. I watched one other video involving Double Lip Seals after watching yours, downloaded both, reviewed them and hope I chose the correct position of the seal. Close ups would be appreciated, but I understand the thought process and time constraints. I value your productions. I have always worked on my own bike following the Manual but also relied on a trusted advisor who passed a few years ago. I am no longer able to ride but want to set the bike up, a 76 Glide, for my son before my shift is over. You are, unequivocally the best and I especially appreciate that you are answering the call of the wild.

[@pacificmike9501]

Thank You. I did my best.

[@Madness66]

Somehow this is a faulty design as I understand it. It can't be completely sealed because there is no seal or O-ring between the spacer and the mainshaft. Shouldn't you use Siliokn between the spacer and the shaft to prevent oil from traveling between them? Spacers rotate with gear shafts.

[@pacificmike9501]

It's an antiquated design. There are little tricks here and there. The later four speed main drive gear has a seal between it and the mainshaft. Sealant on the back side of the sprocket can help. A "supernut" sprocket nut may or may not fit in your application. But, no matter how you do it, it's temporary and you'll be doing it again in the "not so distant" future.

[@Madness66]

@pacificmike9501 Thanks for your quick reply, I really enjoy your videos and learned a lot from them.

[@Swan-me2fy]

Mike, I watched all of your video on the trans-seal replacement and I can't for the life of me get the trans mainshaft drive sprocket off. I got the nut off, with the correct tool/socket breaker bar and stepped plastic wedge, without any issue but the sprocket won't budge. I think this is the first time the primary was off because the oil line had a crimped hose clamp. I have a 1971 FL. Should I use a gear puller or pull the trans and bring it to my local indy? Any help would be greatly appreciated.

[@Swan-me2fy]

[@jeffadickes4039]

I have a 1948 Panhead 4 speed and have the transmission ready to install a new main gear drive spacer and seal. The new gear drive spacer is identical to the old one but is slightly tighter and will have to be tapped on the shaft. Is this correct or should it slide onto the shaft and be able to turn to float side to side??

[@pacificmike9501]

You could go over it with a little emery cloth on the inside, or, if a light tap will do it, you'll be fine.

[@pacificmike9501]

[@hightechred]

Mike you put the cork in the wrong order relative to the removal portion. You removes the cork before removing the spacer which means the cork is between the seal and the spacer, or am I confused.

[@rrumbler1]

Invaluable content so glad its available, thanks Mike. My questions is to what torque does the chain sprocket nut need to be tightened? I've scoured my manual and could not find a procedure, simply reverse of disassembly, in that case it would be an 1/2" impact. In the torque values at the end of the chapter it indicates 105-120ft/lbs for Late 1978-early 1983 (I have a 1980 FXWG). Once tightened to that torque spec the sprocket becomes difficult to turn by hand, although the Mainshaft spins freely. Is this normal, in your video the spocket seems to spin fairly easily before you removed the super nut? Many thanks, Todd Beach Santa Barbara, Ca

[@pacificmike9501]

I believe you're reading the torque spec for the motor sprocket, rather than the trans sprocket. I don't know of a spec for the trans sprocket nut. Now, make sure that your parts are in order. Glue yourself to the parts manual. Things changed in those late Shovehead years. Be sure you have the right sprocket. Some of those late ones used a spacer behind the sprocket. The worst part is, some of the years are interupted with changes. Use your best logic, your vin number and compare parts.

You've asked a reasonable question. I hate to admit it, but, there are things we do when no one is looking. In a perfect world, that tool would remove at it to death.part just as it was designed to do. But when it won't, someone is going to have to hold their breath and get creative. I say "hold their breath," because it gets a little scary. I would probably go at one of those holes very carefully, with a punch and hammer. The idea is to "drift" it loose, not beat it to death. You're going to replace it anyway. The point is to not damage the case. Sorry, but I am retired. I work on my stuff at home. Hopefully, I'll meet you at a show or the Long Beach Swap Meet.

I just pulled my seal out on my 4 speed and have a few questions. I have a gap in the bearings (it looks like a few are missing) should there be any gaps? Or should it be tight enough that you can’t fit any more rollers in there? I have no clue who did the last seal but I’m concerned they did a poor job. Thank you for your videos!

[@pacificmike9501]

You need to look at the proper year service manual. That bearing must be fitted properly. You didn't say, but it is obviously a pre 77 trans (loose roller bearings). That is something that must be fitted properly and you are a few rollers short and the race must be in smooth excellent condition and the right size rollers fitted into place.

[@dilo777]

@@pacificmike9501 thank you!!! I’m not sure of the year, my dad said the bike was a 58, but it’s turning out to be a basket case of random stuff, it does have loose rollers. I’ll pull a few rollers out and measure them to get the right size, thank you again for the info!

[@pacificmike9501]

Full set of rollers and properly honed bearing race is how it's done. Again, please consult your service manual. Have fun.

[@ironmike1093]

Mike where did you get that massive socket?

[@pacificmike9501]

That's a cheapo socket. But, being that large, it's strong enough. It's a 1 1/2" and any tool supplier can fix you right up.

[@markmcsheffrey7174]

How do you know to change that my bro ????

[@pacificmike9501]

Because it is leaking.

Which direction does the large main drive gear seal get installed ?

[@pacificmike9501]

Rounded metal side out.

[@timseaton3386]

Thanks!

[@robmcguire9756]

Mike I noticed that you have a hose on your crank case vent so you don't oil the belt how do you turn the tube to do that.

[@pacificmike9501]

I trim off the end of the breather tube and attach the hose, running it between the crankcase and the inner primary tin.

[@jamesrobinson2433]

I had a hell of a time removing mine off my 73 . Watching this brought back memories of a language that came out of me that I never knew I possessed. Lol

[@pacificmike9501]

Okayfine.

[@Patrick_B687-3]

So what kind of mileage will you get out of a seal on average?

[@pacificmike9501]

Never figured it out. Probably has to do with time on the kickstand, verses time on the road, temperature, humidity. I replace them when they get to the point of really leaking badly. In the old days, things really didn't seal up real well for real long. And, it didn't matter much. We have better seals now, better materials and so on, but we still shouldn't be too critical.

[@creativespridgets]

Thanks for this, Mike. I did it this weekend without a problem, but do have one question. I didn't drain the tranny, and although the seal went in and seals nicely on the new spacer, I didn't replace the sprocket, etc. and oil drained out through the one of the notches cut into the threads onto which the 'super nut' goes. Is that normal? What ordinarily keeps the tranny oil from coming out that way?

[@pacificmike9501]

Sometimes, yes. If this happens, fill the notches with High Temp Silicone.

[@creativespridgets]

@@pacificmike9501 - great, thanks! Also - the PBI sprocket I bought is slightly dished or concave on one side. Does that go toward the tranny or facing out, please?

Hi Mike. I have 2 questions. My tranny is -78, Torrington Bearing, and it don't have the cork seal, when I take it a part, is that right or not? Its also fitted with Ray's o-rings spacer, would you say its enough to change the o-ring then?

[@pacificmike9501]

Most catalogs use Harley's diagrams to show the assemblies. Have a look, V-Twin, Drag Specialties. You'll see and check the parts list for the year groups. The cork seal was used earlier. I don't know what "Ray's O-rings spacer" is.

[@billygage6899]

Mike different subject where does your engine vent hose end, as a chain oiler? I was wondering what you fastened it too on the bike. Just converted my 62 to a belt

[@pacificmike9501]

I don't use it as a chain oiler. I turn off the oiler screw on the oil pump. Then, I run the hose out behind the inner primary of the bike, along the lower frame rail and out.

[@billygage6899]

Pacific Mike Thank you for the information Brother it’s Greatly Appreciated

[@bescol2410]

@@pacificmike9501 Hi Mike, a bit late with the question but I have a 46 Knuckle and I have terminated my chain oiler similar to yours but I still get oil running out of the hose. Do you get any oil spilling out onto the tire or is there something I have overlooked which could cause the oil leak

[@robmcguire9756]

Hi Mike I'm changing the seal on my pan and the gear spacer is hammered and stuck is there any way to get it off or am I boned.

Tenacity. It's sometimes hard to do. But, there are no other choices. Once you get it to move a little, just keep at it.

Hey old buddy I wanted to put in my two cents it probably might be some help 1975 FLH help having transmission leaks you might want to touch on you there's a screw that vents the transmission however on mine the guy must have went outside on a break chugged a six-pack of beer and smoke two joints came back off brake woke up in a brand new world forgot to drill the vent screw so I drilled it out problem solved hello what was that guy thinking about Great information thank you for all your videos and your input and time you are a great American

And now the question is why? Is it simply old age (the atmoshere does deteriorate them over time). Was it aligned properly?

[@eazyrider6122]

Hi Mike, I noticed the red fluid you use?. I have a ratchet top 4 speed and use HD 50/50w. It looks like your using a trans fluid?. What fluid do you use for that trans please?.

[@pacificmike9501]

Back in the day, Harley recommended the motor oil used in the motor should be used in the transmission on all Big Twins. That was a long time ago. Since then, the advancements in lubrications have been huge. Today, I use 85/140 gear oil manufactured for use in motorcycle transmissions. There are several great quality brands out there, and, without conducting a real study, I couldn't say which is the best. Sportsters need different specifications because the translube and the primary share a combined system.
