How did you order the bearings? There is a huge counterfit bearing =
manufacturing market. I have lost count how many times over the last 6 =
years I've had to investigate them. The last set of ball bearings I =
bought were skf but we're obviously not legitimate. I took it with me =
to skf on a visit and confirmed it was not made in any of their =
factories. =20

If you've got concerns of counterfit bearings send me some pictures and =
I can help.=20

John,
Replacing the old bearings because they were worn out. New =
Timkens seem to be the best available option.

Some of the USA-stamped Timkens even look cheap when you compare them to =
the England-made. I wouldn't be surprised if they were made overseas. =
If there is nothing wrong with your old bearings, why replace them?

Has anyone else noticed rather large variation in carrier bearing =
width's when rebuilding a spitfire differential? The one I'm building =
right now, I've replaced what I suspect are the original bearings =
(Timken England) with brand new Timken USA bearings. In order to reach =
the required .004" preload, it will require .012" LESS total shim than =
what was in there originally. That seems like a big difference with the =

carrier, the bearings visually look to be fully pressed home. Anyone =
else experience this?
