Oil leaking from generator gear pulley

    Hi 101 members, just finished my 1928 101 and I have noticed that when driving at 45-55 mph oil is getting pushed out of the generator gear, and is getting on the battery box and surrounding area. 

    I talked to Kent Thompson and he said there was a service shot of that issue and a repair recommendation. If any one is looking for parts, or advice, Kent Thompson has been a great resource. 

    If anyone has that service shot if they could email it to me I would greatly appreciate it.

    Here is a photo of my 101. Im also looking for a 1931 project if anyone knows of one. Thanks, Wayne

    Basically in the service shot is described there is a oil supply hole drilled for the bushing at the top in the gear housing. That hole is plugged and a oil draining hole is drilled at the underside of the bushing instead. Check out and scroll down

    And please support him hosting this valuable info.

    Hopefully that link will help cure your problem, Wayne.That usually works better than installing a seal, which is irreversable, and wil blow anyway when bearing gets worn.

    Also a possibility that the crankcase pressure is affecting primary and tranny. Is your timing case breather working well?

    I disassembled my generator drive adapter and  mine was the later 4 bolt type. What I found is that the bushing has a drain hole that did not line up with the drain hole in the casting. Once that bushing was removed and re aligned that cured the piling issue I had. Thanks
