Thanks Tubs, My gearcase and pump looks much the same but I have a one piece driveshaft and the hole in my pump is only 7/64 and the bolt that is in mine is a slotted stud affair with the jam nut and no pin like end…looks like a regular bolt end. Should I grind the end to a point which might slide into the hole before tightening the jam nut to lock in the pump? Or should I check with the Penns to see if they might have the correct bolt? otherwise the gearcase looks to be in good shape. Then onto finishing the magneto.
