Working on a `42 WLA. Installed new main races on both sides. I'm set-up ready to Line lap and size the bearings. Manual says .0005-.001 clearance for the sprocket side and .0008-.0012 clearance for the pinion side.
OK? Now how do you measure that? I'm using the TM 9-1879 military manual and most things it explains really well, this it don't.
My flywheels are still apart so using the sprocket shaft and pinion shafts as gauges is easy.
Only way I can figure is micrometer to measure bearing OD with shaft in and bore gauge to measure race.
Or, am I over thinking it and the numbers are arbitrary and it's more of a "feel" thing.
