Title: Crankshaft bearing clearance?
Post by: Carl Hill on November 30, 2020, 02:38:54 PM
How are folks checking width on crankshaft when installing new bearings? I was able to use a depth gauge to get dimensions for the cases but 2-3" micrometer will not reach far enough down the crank to where the shims go.

Carl, the way I do it is, I install the inner races on the crank with out shims and assemble the cases with no transmission installed.  I use a dial indicator on the end of the crank, get total axial float and adjust from there.  I've found this easier to do than trying to measure the width of crank, depth of outer bearing races etc.  Make sure you have the seal holder installed on the mag side when doing this. This works for me.
