Was it the main shaft or the small shaft that sticks out the back that drives the gear pump? I had one break the rear shaft tab because the gears got stuck or something. Did something similar to yours but i couldn't even get it started. I fixed it by grinding a notch in the shaft like a flat blade screw has. carefully welded a piece of steel in it an it worked

This one did the same thing but I think it has other issues also
