<p dir="ltr">Jim, do you know the set that includes the 15123/15245 bearing/race used in the earlier gt6/spit differential? <br>
The sets for the later differentials are easy to find, but I've had no luck with finding the earlier ones in a set.<br>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri;color:#1f497d">.012 would not surprise me for stack height variation. My guess
is that he ordered by bearing NUMBER-not by bearing assembly. There is a thing
called “half stand tolerance” that would cut his error in at least
half. There isn’t really an issue here-he is just seeing the standard
deviation in assemblies, and that is why they have to use shims to get it
perfect. The original assembly probably has that stand tolerance and over time
that information has been lost. Each assembly throws off a unique set of
dimensions. MORE SHIMS!!!!!</span><span style="font-size:11.0pt;font-family:Calibri;color:navy"><u></u><u></u></span></p>

overseas. If there is nothing wrong with your old bearings, why replace them?<u></u><u></u></p>

<p class="MsoNormal">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 <u></u>England<u></u>) with brand
new Timken <u></u><u></u>USA<u></u><u></u>
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?<u></u><u></u></p>
