[Fot] variation in Timken carrier bearing width?

[malaboge at aol.com]

Jason,

Just went thru the same issue with a big TR diff.  The major suppliers provide slightly different bearings at about a $40 to $50 price point. The original bearing is available for almost $500 !!!!
The numbers on the bearing are the same except for the suffix on the bearing (15100 vs 15100SR in this case). Both will fit, but the differences include thickness among other specs.
Check the numbers that you are using carefully.

Been called a bit off spec myself...

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 only variable being new bearings.  I'm using the same housing, same carrier, the bearings visually look to be fully pressed home.  Anyone else experience this?


Thanks,



Jason Sukey
