Robert:
Not to worry about the scored surface. If you replace the
bearing with
the solid cage variety, then the bearing will not be riding on the
scored surface
but on the outer race, and everything will work fine. The problem is
getting the
old bearing out, as the outer race is hardened and a booger to remove. A
small
grind stone and a Dremel would make short work of it, probably. May take
a couple
of grind stones though, as that bearing race is HARD.
I would think a bearing supplier would be able to work with you
to find a
suitable bearing if you have it bored, HOWEVER you need to find the
bearing first
so that the machine shop knows how far to bore out the cluster.
By the way, on the cluster you can omit the spacers for the free
caged bearing
and install a longer bearing to take up the extra space. This will give
you more
bearing surface and make the tranny rebuild last longer. And make sure
your
layshaft is properly hardened.

I've complicated things a bit I think. Once I pulled the cluster out,
and inspected what was left of the bearings, I decided to pull out the
old bearings so I could put new in on both. One the one end, I must
have used the open cage type. There was nothing left. The other end,
though, had the solid cage and I decided to take it out. Bad move. It
has kind of welded itself to the mating surface. In the course of
trying to get it out, I've only been partially successful, and have
scored the surface in a couple of spots.
So here's my thought if you guys agree. I think I should take it to a
machine shop and have them clean out the old material, and if
necessary, bore it a little to make sure the mating surface is clean
and undamaged. Now obviously that means a new bearing with wider than
normal outer diameter. Is it possible to do this? That is, will they
(or someone) be able to find me and larger outer diameter bearing with
the same internal diameter? If not, what should I do, replace the
cluster? It's otherwise undamaged...
Thanks
