It kind of sounds like you might be doing something wrong.First 3/8 is maybe too thin for the puller.The puller has to be a little smaller than the sleeve so it wont hang in the block.You have to have some kind of legs and a piece of all thread or some kind of threaded rod and a bar to go across the legs and that bar needs to be stout.Plus your legs need to be away from the top edge of the sleeve or you cant pull it.The thing to do might be to look at a picture of a sleeve puller and make one like that.What you do is you tighten up the threaded rod and it ought to pull the sleeve.If you do try welding on the sleeve you want to cover your crank so it does not get any slag stuck to it.Metal preferably because a rag might catch fire.Also you want to get it clean around there because right after you strike an arc there will be a fire wherever there is oil under it and if its greasy you could have trouble.I think maybe you can pull the sleeve without welding on it anyway.Others would know better about an Allis Chalmers because I have not worked on one of them,but usually wet sleeves pull out easier than dry sleeves which are the kind that it helps to weld on.You might be right about heating it a little,you want to be careful doing that.I would say heat it around the top where the sleeve fits into the block and down about where the o rings are.300 might be hot enough.Then let it cool off.I dont know if you want to pour water on it,but maybe go eat lunch.Come back and try it then.You might want to hear from an Allis Chalmers mechanic before you do any of that stuff.

The generator was shot as well as all the wiring. I dropped off the tractor expecting a transformation from a 6 volt to a 12 volt system utilizing the original generator housing, and a total rewiring of the whole tractor. The front end center pin bushing was worn also so I ask that they replace it if they had time. Well, that’s wha
