He doesn't take the bearings out while he's grinding?Joe_Knesek said:I don't do it myself but I do know that some of the engine builders I've used do it as part of their process on CMB's.

I was thinking the same thing. It must be the needles in the crank/rod assembly on the EVO motors as they are a pressed assembly.Preston_Hall said:He doesn't take the bearings out while he's grinding?Joe_Knesek said:I don't do it myself but I do know that some of the engine builders I've used do it as part of their process on CMB's.
