right crank bearing

davomoto · Post by **davomoto** » Wed Jan 11, 2012 8:39 pm

I'm just starting on my 63 CB77 engine, # CB77E-311186. The right crank bearing shaft has some pitting, caged roller side. Is there a replacement bearing that can be used, similar to the left crank bearing? Part or bearing number?

Thanks, Davo

Doing some searching on the internet, it looks like 91002-259-010 is a ball bearing for that side, instead of the roller bearing, also shown as 63062. Can anyone confirm this?

Thanks, Davo

You are correct Davo. .........lm

Thanks Ed! Looks like that is a readily available part. I'll try ordering from the dealer in San Francisco.

It's a cheap (if possible) fix for a bad crank bearing surface. ...........lm

Yeah, that's what I was thinking! I checked another 63 crank that I have, and one of the inner bearings has pitting :-( . I thought I remebered you answering a post a long time ago about the same subject, and figured it would be the way to go!

Back to working on this motor. I got the ball bearing, andf it has a metal shield on one side that faces the crank when installed. Is this correct, or should the shield be removed?

Thanks, Davo
