Hello, I'm new to this forum but have some experience working on lawn and garden tractors. I am currently working on a MTD yardman 14au804h401. It has a B&S Vtwin engine model 40777. The engine is completely out of the tractor. The tractor I'm working on has an electronic PTO that was attached to the crank but has been taken off. The only pulley left is the drive pulley which is causing my problems. I have 2 oil leaks. One coming from the seal and some seepage from around the sump gasket. The drive pulley that is on there does not seem to have any stop bolt or screw. It also does not seem to have a traditional key in the keyway. The pulley has an indentation on the pulley that sits in the keyway's groove. I have tried using 2 and 3 jaw pullers as well as soaking it in penetrating oil. all it did was start to bend the pulley. I also tried using a pulley puller but it also started to deform the pulley. I've applied heat while using the pullers and nothing.
So I guess my question is, is there anything else I can do to get this type of pulley off or am I going to have to cut it off the crankshaft. I have not tried using chisels on the bottom yet by the seal, but I don't know how far down the collar of the pulley goes and I don't want to start pounding on chisels until I get some better info from more experienced individuals.
Thanks for you replies and ideas
