Usually harder to remove from engine than to rebuild,Id clean the 3 set screw holes and start soaking with PB blaster even if your sending tractor and all to shop it will help them out but I would think your looking at several $$$. If your unsure of doing it yourself you also might end up spending $$$ and be in the same situation ! Might be some members here that would rebuild it for you at a nominal fee and shipping if you get if off tractor or a member in your area not to far away ? doesn't hurt to ask ! good luck !
