I am not 100% positive about the following info, but I think
the breakdown is as follows:
- The 4U & 4UA crankshafts have a 1.85" converter pilot hole in the rear flange
- The 4UAB crankshaft has a 1.375" pilot in the rear flange.
If the above is correct (and I'm fairly sure it is but I'm not positive), then the 4U and 4UA cran pilots may be bushd down to a 1.375" pilot. Yes, a machine shop could do this for you. Measure the rear pilot diameter of your 4U crank to confirm it is 1.85", but don't press in the bushing until you also look at your 4UAB crankshaft for comparison/verification.
P.s.: We may have a 4UAB crankshaft over here if you need one....
