Yes!
I have run into that on several occasions but can't remember the Timken 
numbers, nor do I have a technical explanation.

Subject: [Fot] variation in Timken carrier bearing width?



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
