I've picked up an old snowblower made by McKee Bros, model 500. It had a top gear with a chain that drove the bottom gear on the input shaft of the gearbox. I have removed the chain and the top gear and would like to remove the bottom gear so that the pto shaft attaches directly to the gear box. However, I'm having trouble determining how that bottom gear is attached to the 1.25 inch input shaft.
The pictures show that there is a collar on the shaft and the gear is keyed onto the collar. Also there is a shim between the gear and the collar. I've got the large key almost out but the gear will not move even with a 3 pronged gear puller. The mystery to me is how does that collar attach to the shaft? I don't think it would be a woodruff key. Any ideas?

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
