Thanks.
I'm in process of rebuilding a CB77 and my uppercase didn't show that oil hole that you have in the early case.

No they are on the side with the other markings. Just a bad photo from that respect.

Thanks for putting me straight. I was looking at the differences between two bearings rather than the cases.

It's amazing what we miss when we aren't looking. Mistakes can be expensive with these rare old machines. It's great to have all of the experience of this Forum.

It's probably a good idea to machine a channel under the bearing towards the seal for oil to migrate if you're ever going to install a ball version in the later cases.

Under the bearing or from the oil feed hole in the top case outward?

Yes, machine a grove in the case from oil feed hole under the bearing outward toward the seal.
Otherwise the bearing will only get splash.

Your welcome!
It's all about the little details that makes the average rebuild seem kinda poor.

It's impressive to see you be interested in doing a 1st class rebuild. Welcome to my world.
