Rebuilding a 4 spd transmission (+++PICS)
Hey how's going? This 4 speed transmission has been rebuilt twice in the last 5 years to the tune of $2000 dollars. Well it leaked like a stuck pig within a month of being rebuilt last time. I have now taken the bike over from a family member to help solve this leak problem. I can say it leaks from the clutch rod shaft opening and from the main shaft itself. Does anyone know where I can get some info on changing all the seals? I've ordered up a JIM's master gasket/seal kit. Here's some pics so far..I will provide pics as I go along. If anyone has any tips let me know.

Why would someone put a rotary trany on a bike that should have had a ratchet lid !!! These trany's were inferior HD's solution to installing a rear belt drive Are you going to install a rear belt in the future ? As you can see I never liked these trany's Maybe install a 5 speed in a 4 I run one in one of my customs (96 CI S&S ) I love it

For now I'm just looking to get it from leaking. It's blowing up primary belts from soaking them in oil. Got stranded big time last year on a ride... The tranny itself shifts fine for what it is. No plans on a rear belt just bought a new chain for it. What can i say, it's old and I can't afford a new bike right now..

Here's a great turorial on how to change the seals on a ratchet top older model 4 speed I thought was worth sharing...update on my build..the main shaft is on it's way out today pictures to follow..

I found the culprit. The main bearing seal spacer had a lip worn in it and a fubared O-ring. Exactly what somebody on this side told me would be the problem. Here's some pics of the progress so far. The key to removing the main shaft is to find the circlip and slid it up over the splines..i missed it the first time looking around.
