When installing the oil pump kit, pressed the split bushing into the hole with a the side hole lined up with the drift hole in the pump housing used for lubrication.
The machine shop used the same machine as used for the rod bushings to ream the split bushing to size for the driver gear. About .01" had to be removed on the wall of the bushing to fit the new pump shaft.
The reamed split bushing hole was not exacly centered and about .003" offset towards the driven gear shaft.
With both gears installed the gear teeth clear the housing, but two teeth have some sliding noticable friction when rotated by hand. The other teeth have no noticable sliding friction. Hoping the the two teeth will "run in" when the engine is first started.
Agree that a new separate non split silicone bronze bushing drilled, bored and reamed on the lathe is the preferred method, since assured of concentricity.
