Lynn , this thickness varies, because when you do the preload set up , new bearings can require this to be thicker and older more worn bearings will use thinner gaskets, so there is no real given measurement, other than using .010 as a starting point, many times we have used 2 or 3 gaskets together of different thickness to get the required preload. I had a heap of gaskets lasered up , so we have the different ones on hand for the job. Usually set up preload with the pinion out, so you have access to move the crown wheel. Bolt the 2 halves together with 6 bolts try, change gaskets if necessary, try again.
