The new GENUINE mainshaft I have here measures 0.8101.

According to the factory manual, the minimum ID of the High gear bush when FITTED is 0.8120. That makes a min clearance of 0.0019.
The maximum ID of the bush fitted is listed at 0.8133, which would make for 0.0032 clearance.

I do not see those as service wear limits, but rather as the normal running range.

This info, from the HD shovel manual, gives a similar view.

Main drive gear bushing on mainshaft (loose) 0.0018-0.0032.

With a service wear limit of 0.0018-0.004.

Same application from 2 different manufacturers, with essentially the same spec.
