Peining Rear Mains
When peining main bearings with an air hammer, especially the rear main. Do the mains need to be supported in a peining clamp while doing this? KRW clamp works great on the block but not so much on the rear main cap. I know the front and center caps are tinned as they are forged but the rear is most often (but not always) cast which requires peining. Pein the thrust faces as well...?
