Need help fining seal in parts manual

ohjeffoh · May 17, 2019

I've looked and wasted too much time now I'm asking for help. We have a 3020 syncro range upper s/n range above 152,000 leaking oil into clutch housing I have it split and want to change all seals that could leak no problem finding them except for the one on the pto shaft where it goes into the trans housing.

Your leak could also be part number 29 in the pic. You need to split at clutch to replace that one. Tom

R33578 is your illusive seal.
Normally leaks (if not engine seal)in the clutch are from pto engaging pistons.

Thank You so much, I forgot to mention I did call the parts counter for help and was told sorry I looked for 10 to 15 minutes and couldn't find it either, not ragging on the parts guys I know that's a tough job I used to do it for a while, thanks again D-
I am changing every seal I encounter in there including the rear main, clutch engaging pistons, o-rings and seals, and yes seal 29 and now this seal that I couldn't find.

And that seal changes form the back side, which means another split...

Don't remember ever having to replace a leaking one.
Usually replaced them when tran was split.
Then again there's a lot of things I don't remember.
