385 needle bearing let go today

[Tor R]

Looks good. Smooth as silk.

that is great news.
Personally I would split the case, or pull the seals for propper cleaning.
You dont want those small leftovers from the bearing to pop up later.

You can't pop the seals off and see anything unless it went past the race any way.

I was mostly thinking when we flush a crankhouse and the risk to blast the remaining parts of the bearing into main bearings.....easier to clean without seals, can at least be cleaned both ways

I sprayed mine out good with brakekleen, then filled with mix and ran the crank around a bunch of times. Then sprayed out with air and brakekleen again. Bearings felt great so I put some straight oil in the crankcase and ran the crank around till I got all the bearings covered and slapped a new top end on her

Integral seal on the clutch side is a pain. They make it separate but I don't know if I could get in Mt installed correctly

That's a forty dollar combo seal/bearing.
