I have replaced the linkage between the crank and the hydraulic pump multiple times. It is operable again, but through my research, I have come up with some questions.

1. Is there a relief valve or check valve on these machines that might be faulty?

2. The linkage from the crank has only about an inch long bite on the spline from the hydraulic pump. Is that enough?

Thanks for the help!! (I wish help with this machine were the only help I need.)
