Engine is in Bits, Crank is out for balance.
Main bearings are C3 spec and by all appearances, appear to be fine.
Crank play about 22 thou. Unknown mileage on bearings.
So, Do I replace just because, or reinstall?
I ask because years ago I did a remodel project at a shop that makes Gears.
From NASA spec to JIm's Harley's gears and so on.
Owner is litterly a real Gear head with Hot Rods boats etc. Knows his way around.
Shows me around his shop and stops at some bearings.
Starts talking about bearings and how everyone is in a hurry to replace bearings.
Explains how in many cases the used bearing is better because it's been polished in use.
New bearings have micrscopic burrs, that get polished out in use.
You also have a known performer with the race and cage, anything new can fail.
So what to do?
A real conundrum..
