I have torn a M18 down enough to replace a grenaded governor gear. Since the engine in question ran great other than being unable to control the engine speed, I was able to keep the piston in the jug, and still disconnect the rod from that piston, so I did not need to pull the head, or remove the rod from the crank. I split the block, replaced the grenanded gear, cleaned all of the nylon bits from the sump, realigned the cam, then reassembled. It runs great to this day.
