Output bushes are normally bored after clocking in to ensure concentrity.

I picked up a pair of pot joints and output covers with new bushings today.  Latter reamed/honed to give 0.001" running clearance.  These are for the A+ tranny build going under the 1293 for the Woody

Nothing special right?  Well, just a tad problematic.

I took 3 new pot joints to the machine shop...there was 3 thou difference in their input shaft outside diameters and one shaft was both oval & tapering.

All 3 were ground/polished as required to get to a common size - 2 now finished.  The 3rd new bushing too big.  Took other new bushings up to the shop.  It has one that can be reamed/honed to suit the 3rd cover.

Need two more covers bushed for the 1185's transmission going into the OZ van.  And 1 more for my partner in power unit building. 

Lesson measure everything...
