The gear on the end of my starter drive was badley worn. The flywheel looks to be ok, thang goodness. I replaced the starter gear assembly with one I ordered from Steiner. It was part number abc458. It seems to be the correct assembly, but I has to tap the back end back into the starter housing. The gear on the starter drive that connects to the fly wheel does not spring back back. Which position is it suppose to be in upon installation into the tractor? Towards the flywheel, or should it be back towards the statrter housing? I'm not sure exactly how the gear assembly works with connection to the flywheel. I would assume it does not stay engaged, so does the flywheel force the gear back? Pics are comming when it is put back together.
