I am putting in a Quaife TBD. I pulled the shims/spacers off the old differential. and did not note which went where. One is around .010" thicker than the other. Was this how they set up ring and pinions back in the old days? Is there a spec for this somewhere?

The “thinner” shim is usually on the ring gear side.
Also when working with these shims it is best to use metric measurements, the math seems easier whereas engines thousandths is preferred. Pinion depth is set using shims on the pinion shaft than micro adjusted using gaskets between the case and the intermediate plate. If you removed these shims, you should be able to replace them and use the same thickness gasket for the pinion depth. The backlash is what needs to be set when changing differentials. The new differential will be a different size requiring different size spacers. The spacers vary by .1 mm with an additional shim at .05 mm. Measurements start at .1 mm larger on the ring gear side and adjusted by changing spacers to get the correct backlash. |
