I have been riding and wrenching Harleys since the mid 1970's. I have re-built maybe 6 or 7 engines and 4 transmissions, certainly not a lot by anyone's standards. Each time I watch one of your videos I get simple, common sense tips that promote reliability. For this I am grateful that you have taken the time to produce these videos.
...So...you think that's bad? When I bought my 46 Knuckle, the threads on that main gear were so broken off from hammering on that big nut, the previous 'mechanic' just welded the nut, threaded extension and sprocket all together.....After replacing all that stuff and new seals (and buying a big socket)....no leaks.....and that was over 30 years ago.....
I used a 1977 non keyed spacer and torqued it down and lightly ( impact gun set on the #2 setting out of 5). This is also on a 72. Now the sprocket is super tight, and barely turns. What'd I do wrong? I did measure the 77 spacer against the 72 spacer and the 77 measure .030 thicker. I wonder if that is causing the tightness. I'll pop the old, keyed spacer in and see how that feels.
you might have the cork seal stuck under the spacer instead of being around the spacer like it should. i use the -77 spacers all the time without any problems. always put thee spacer in the seal before you install the seal and make sure the cork is down in the holes too. tatro
Your knowledge of this stuff is unbelievable. I don't understand how the 80-82 spacer washer works. When you torque it down, wouldn't it just push the seal further in?
i could but then it would be dragging. seals don't work very good when they are being jammed into something. this is an older video so i am assuming that the spacing washer was needed for seal clearance or to offset the sprocket for case clearance or sprocket alignment purposes with the rear wheel or sprocket. tatro
Wow that's a good idea with the 5 speed seal on the 4 speed main shaft Thats a Good Fix i Have to try That Next time i do my 4 speed trans but i have the newer trans 79 witch looks way better then the one your working on ! great video ! My Shovel Allways Marks Her Spot Right From my trans from that same seal i for got to change it
Sometimes it easier to just jerk that new inter seal out and start a new 1 again. Seals are cheap, BUT make sure you know which way the lip is supposed to be.
The 5 sped seal he said was 10 thousands larger in diameter so, I can’t see how that would be a good fix. I understand the issue with the gear being broken out but the seal was deformed when he installed it and if the outer nut was going to seal it as well, I think I’d have put the correct seal in. I don’t see the seal he put in lasting too long. Just my thoughts.
So your driver setup for the mainshaft nut: took a socket, drilled the square drive hole big enough to fit over the mainshaft and then welded a section of pipe and then welded that to another socket? Si, si...no, no?
Everything I've tried over the years has been in vein as the transmission would still end up leaking. POS design if you were to ask me. Major PITA to get at too (outer and inner primary). I don't know what made me so brand loyal even after 35 years of ownership and 6 different models, I must be a glutton for punishment. My brother has 4 Harley Davidsons and 3 are broken and need something. ALWAYS somethin...
Tatro Machine hey Tatro'? I have a 99 twin cam with the rear Rod out. motor has 67k on the lower end. just off the top your head what's a lower end rebuild cost.
new s&s crank is around 1300 and main bearings are around 160. if you can set-up the timken bearing you can do the job yourself. not too much fitting on twincam motor. they are made to be put together with machines, not humans. tatro
@@TatroMachine nice decision by some dumba$$ Engineer to remove the Timkin bearings from the equation. He is probably retired now and can give a rat's as$ about HD.

Some day, after watching all tatros vids, I'll be able to put a bike together from swap meet parts and then fix it. Awesome videos!
Always eye opening what a little patience can do for you.Nice work Tatro
Recently found your channel. Enjoy it so much. Thanks for sharing your knowledge.
This is so awesome!! Thank you for sharing your knowledge brother! I really love Harley Davidsons thank you again
Great series .Thanks for sharing.

I remove the mainshaft bearing ream it and put in later model needle bearings as well ( works all the time )

Yeah, that's what I did. I put the cork in first, then the spacer. Its under, not around, the spacer. I gotta figure this out.
Over and over the words keep going through my head "that seal in done son" 30:23...Pull it out and get a new seal.

needed your TLC

Is it better to use 5 speed seal than 4 speed seal? Thank you Tatro

and which way would that be.

All that to ruin a seal

totally different parts. use what fits.

Tatro, this ain't the first time you're having to fix somebody else's mess. I'm beginning to see a pattern here.
So your driver setup for the mainshaft nut: took a socket, drilled the square drive hole big enough to fit over the mainshaft and then welded a section of pipe and then welded that to another socket? Si, si...no, no?
no, i cut the socket and add the tube in the middle and weld it all back together. i add a 2nd socket if i need a 1/2" drive square end.
tatro
what type of three bond do you use?
1184
👍😁😁😁😁
Church bells in the back round? Saint keanen? at work on harleys ?
when the wind blows just right you can hear them. most of the time you can't. they are not close.
tatro
You will never get that 10 thou oversized seal out if ever ….?
Some people should just throw their tool boxes in the dumpster!!!! It would make your job a little easier
no fun in that.

that is why we like them so much. we get very involved in them.

So I'll be watching any video that you have about shovelheads LOL........
do i need one?
