Hi steve Not wanting to tread on the toes of the retired crank grinder.it seems to depend how far the hardening goes into the crank. I have a fordson 6D motor that is at 30 thou and the hardness is all gone she has cut ridges in the crank in no time. 40 over is a waste of time for this but you can buy shells. I have to get her spray welded and bought back to new spec as it wont last again. I think there are some perkins out there that dont take to kindly to grinding atall. It seems that my crank guy has 40 plus under the belt too and experienced a lot of different stuff. He will just say dont bother to bring it just bin it on certain things when I ask. Regards Robert
