Question 1985 flhtc leak prob

*I have bought a 1985 flhtc and love it. This is my first Harley and have spent the last 1st month riding and diagnosing a primary/tranny leak. We have changed all the primary gaskets (I have a nonmechanic for a friend that is helping me/tools). I am still leaking about a quarter size spot a night. I am thinking about using some die to drop a few drops in the tranny and see if that is where the leak is coming from. Thoughts?

*I am going to collect the parts to do the job. From where is the problem? I have spoken to some techs and they say the is a bushing, spacer or something that can get pushed and it will leak. They say that if the shaft is able to move I have a bigger problem than gaskets or bushings. Any knowledge out there on this issue? any othe post will do. Thanks

Shifter seal or pulley seal.... going through the same problem on my old evo... just having to ride it and live with it.

My primary cover is also leaking as well... leaks all 3 fluids.

The leak on the tranny is most likely coming from the mainshaft bushing in the main drive gear. If it is worn (and they usually are) then you will keep replacing the mail shaft seal until it drives you nuts.

Feel the oil, is it heavy (tranny)or lighter like engine oil ? Heavy it the mainshaft or the tranny seal meaning the primary's coming off. Lighter is primary only related, could be the drain plug leaking, the big o-ring on the engine boss is seeping, the inner primary seal or a few other not so common things. Ride it, wipe down the underside or the primary well and using a mirror the next day to track where she's bleeding from.
