I have a hydra-power press brake model 55-10. Today I tried to bend 8 foot of 3/16 mild steel and it will not even begin to bend. My question is what psi should the pump be putting out? Under load my pressure gage reads 800 p si which seems very low to me. Machine is at least 40 years old and I'm jus t looking for conformation that I need to rebuild the pump. I'm not sure of the maker as I am having a hard time finding it online. Serial number is 6
55047860. Machine works great under less load- posted
