Oil in Rear Brakes

[Ben]

I've got a PW50 that has oil finding its way into the rear brakes. Got it apart and to my surprise there is no seal.

The bearing was fairly loose in the housing and easily came out. Have not bought a new bearing, yet, feels fine.

All I can see holding the oil back is the one side bearing dust shield.

Am I missing something here?

Thanks!

rear ring 'n pinion doesnt use oil, it uses some wicked molybdenum shaft drive grease. If you have OIL getting in there, then the driveshaft seal up by the engine needs to be replaced.

Once that's fixed, be sure to get some shaft drive grease from a motorcycle shop and RE-GREASE the ring 'n pinion gears.
