I am trying to disassemble the Harbor Freight 6" tool grinder, so I can pull the rotor and double ended shaft, and true it up on the lathe. I am following the YouTube videos by ghostses doing my disassembly.
However, the shaft is retained at both ends with a split roll pin that functions as the key for the grinding wheel mounting plates. I can't remove the shaft from the motor without removing these pins. The roll pin are inside a blind hole in the shaft, so I can't just drive them out with a pin punch.
The videos don't show how to do this. he mentions the split roll pin, but doesn't show how to remove it.
I don't know how to extract it from the blind hole. Is there some kind of tool to do this?
