Terry Harper Posted August 16, 2023 Share Posted August 16, 2023 (edited) I believe its a Hercules. I have service and parts manuals that covers many models including the RXB, OOB, QX series and WX series. Tonight I will look and see what I can find.

Terry Harper Posted August 16, 2023 Share Posted August 16, 2023 The manuals don't mention it specifically, but I believe (key word... believe) that there should be pin and of course its keyed and is probably a snug interference fit. Do you know the bore diameter? I might be able to match up which model engine it is based on that. Link to comment Share on other sites More sharing options...
junkyardjeff Posted August 17, 2023 Author Share Posted August 17, 2023 Bore is around 3 -13/32. Link to comment Share on other sites More sharing options...
junkyardjeff Posted August 17, 2023 Author Share Posted August 17, 2023 The part the hand crank fits in is the nut to hold the pulley on and the pulley looks to be keyed,now to get the pulley off without damaging it. Link to comment Share on other sites More sharing options...
