I have a PTO driven hydraulic pump that I took off of a 1970s vintage Ford dump truck. The only markings that I can find on it read DCH-22-121. Anyone know the make of the pump, displacement, flow capacity and recommended RPM.

look on e-bay or google your #'s and pto pump, almost all grain trucks and dump trucks used similar pumps with 1or2 built in valves, usually 2 stub drive shafts for r/l rotation, gear type. piston types may be more desirable, more pressure? make great log splitter pumps!

Exactly my idea. Just wanted to know what my rpm should be and how much horsepower to turn it. Was wanting to drive it with a Datsun 4 cylinder diesel.

Yam------Rough rule of thumb was a HP per GPM ...............If I recall . Your Pump wont put your Datsun on it's knees ! Youl'll have the luxury of a throttle to control the lift speed. PTO speed ratio to engine speed might be 1.2 to 1.5 ..

I was thinking of direct drive off the Datsun Diesel but did not want to exceed the rpm rating of the pump. If the PTO to engine speed to engine speed on the original CAT V-8 with Spicer five speed is as low as you state, then I should not have problem s. I can always run the Datsun at lower RPM. If I have trouble, I could keep the Datsun. Transmission to select a lower gear to drive it.
