Thank you for that help.
I bought this machine from a friend's wife just recently. It is something that I wanted to buy from him and after he was killed in an accident, I decided that I would buy it and get it going again. I will really only use it around the house moving firewood, snow, and some loam here and there. I will probably find other uses for it as well.
So with a stubborn streak, I am going to press on and try to repair the machine.
I am pretty sure why the pump shaft and coupling stripped out. The two bolts that hold the pump to the plate bolted to the bell housing were broken. That combined with the lack of any support on the rear(or maybe front?) of the pumps caused it to droop. I carefully inspected the pump shaft today, and found that the splines are not stripped right off, but rather almost ramped supporting the droop theory. All of the pumps can be turned, not by finger pressure, but with a wrench wrapped in rubber.
If someone could tell me if the pump closest to the engine is considered the front or rear pump, that would be great. The pump shaft for the rear pump is still available, the front is not. The other thing that I have found is that the machine doesn't use the universal joint coupling. I have not yet removed the plate bolted to the bell housing because two of the lowest bolts are blocked by the fuel tank. I am working on figuring out the easiest way to get to those. But looking in through where the pump mounts it appears that the coupling is directly on the flywheel. If that is the case, then according to JDPARTS that flexible coupling is also available????
Thanks to all who are helping out. It is difficult not really knowing a lot about skid steer machines. I can do a lot with engines, older tractors, and just about anything mechanical, so I think that I can get this machine back in operating condition if parts are still available. The other option is a little more complex, but first I have to see what is available.
