My friend Bob noticed his 2007 was leaking oil back by the transmission. It continued leaking and it was coming out more and more all the time . . . He thought it was just a bad seal, but the bearing was missing some balls (actually missing 2 complete ball bearings (he popped out 4 more later) Where did the ball bearings go?
Bearing (8) and Seal (15)
The bearing race was badly pitted and breaking away . . .
Bearing is H-D Part No. 8967. (FAG Bearing) If your trans starts leaking, you'd better check it out . . . He asked the dealership how many they had changed . . . They said, "A lot ! " . . . it's usually on a motorcycle with about 28,000+ miles . . .
