The wheel motor has been changed. Seems the body of motor has to be shaved to fit into the opening of the frame. Review of the old motor, one could see where the body was shaved as well.
Lucky for me, my neighbor at the shop is a machinist. The folks at Hydraquip Corp
were very friendly and helpful on getting me some fittings and hoses. I was truly blessed!
Now I am thinking, this machine is pretty straight forward once you spend the time to look at it. Not too hard to service and very durable. Even without great dealer support ( geographically undesirable) I may purchase more of these machines.
