That's exactly where I'm going with it. It may not be enough to just measure off the cap mating surface. Thanks Duane!:thumbsup:
BTW, The 1.631" dimension I specified is half the diameter of the setup standard I have. View attachment 1715415987
Those are some nice pieces in the picture. Did you make those?
There are many tools on the market now that measure off the bearing cap mating surface. I just bought a used 1-6 inch depth micrometer in nice shape for $25.00. I thought I would get more use out of a depth mic than custom tools. I recently read somewhere that it requires a .003 thou shim change on the pinion to see a change in the contact pattern. Measuring off the bearing cap with careful measurements is close enough for a starting point.
Tooth contact pattern and proper backlash should have the final say imho. Honing out a pinion bearing to take away the press fit to make a dedicated setup tool is the best tip to make this job easier.
