Ive got a grader with no engine, and the center section of the pump is busted. Found a 262 gas to put in, I want to know if parts are availabe for the pump. Its a hydreco 078178. What would be more helpful is the specs of the pump. I see surpluscenter has a couple hydrecos

those pumps are only 12-1500 psi. acccording to the book. not a lot a pressure back then. no specs given on gpm but 10-15 should suffice

The pump used on the D is avaialble from Hydreco. I purchased a new one 3 yers ago, about $650.00 complete. I can look at it and provide a part number.

Hydreco is still in business. Part number does not look right. It looks more like a spec no.
