Bit of play

Recommended Posts

There needs to be a bit of in/out, and this bearing doesn't control that. Up down, miniscule. Reason is, these are slip fit shafts, not interference fit like main bearings. These "support" bearings have a very long life however, due to them having a constant supply of oil. The countershaft support bearing is likely the one to show wear first, all things being equal. It is subject to more stress that the other 3 due to direct connect to rear wheel, and chain tension changes during suspension arch.

The way it moves it appears to me that the bearing on the other side of the shaft is wearing. I have to admit I've never done this exact test to check for play.

Unfortunatly you would have to split the cases and remove the tranny to check the other bearing.

You reckon it's something that needs attention now? Or on the next bottom end rebuild? Cheers for the replies!

It's your call. I'm really an "it'll be OK" kinda guy.

So...I think it'll be OK if there's no strange noises when engaging the clutch and no metal flakes when draining the tranny fluid.
