PINION SHAFT RUNOUT

I recently had flywheels and rods put in lower end of my 41 FL and when I install the gear cover it binds a little when I rotate the wheels.I put a dial indicator on the pinion shaft and I have .008 runout where the shaft rides in the bushing.Does anybody have a spec for this I cant find one anywhere and this seems excessive.The bushing in the cover looks to be in good shape and the pinion shaft is the original.

Re: PINION SHAFT RUNOUT

It should be less than .001" and I even consider .001" excessive. It sounds like one of three issues. Pinion shaft not seated square to the flywheel, flywheels out of true, or it is bent. Pa
