Well . . . If it comes to that . . . I got a few in stock . . . but you can probably just get a motor for cheap. Problems like the one you having now is why I love the old school huge single ram setups with the external pumps. K.I.S.S. baby.

Here's a two wire setup that I have up for sale now.
I have another that was brand new in 2003. I even have the receipt from the previous owner who paid $2038.88 (parts and labor) to have the entire unit replaced.
