Re: 1987 332 hyrdaulic pressure
Tracs, looking at the schematics for a 332, I can't see any actual "test port" so your procedure is correct, BUT!
Pressure from the charge pump flows to the steering valve, through the hyd control valve, and then to front ports (when lever is pulled.) You've rebuilt the control valve, so I'd say leakage/bypass in steering valve, weak implement relief valve, or worn charge pump. Also, was 725psi at WOT?
Hitch drifting is worn lift cylinder. When tested, was it pressurized from one side of cylinder and then leak down check, and then from the other side and leak down checked? Drift from lift cylinder can ONLY be 2 things: by passing in cylinder or by passing in control valve. Bob
