Isn't it the same system the M35A3 winch uses?
What are you looking to use for a PTO?

Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
Why not use an open center system? It pumps fluid around all the time using little to no hp because it is at little to no pressure, then (when the flow is impeded by turning a valve on), it builds pressure.You don't want your pump running all the time. They don't make a pump with some sort of "relief" that allows the pump to run all the time. To run the pump all the time you'd really need a closed center system (high dollar and overly complicated for what you're doing).
There are a bunch of things to consider when installing hyd on a truck. What all are you planning on running and what are the GPM and PSI requirements?
Do you understand how a open center hyd system works?
A open center system will work fine but I still wouldn't want it running all the time. The reason I said a closed center would work better because no fluid is moving anywhere in a closed center system when not called upon.OK, understood now but what I am wondering is what I lose by having an open system where the fluid not under pressure recircs back to the reservoir when I am simply driving? I know there will be some temp increase in the oil but if the tank is large the heat should dissipate and the HP lost should not be great since the pump isn't pushing 2500psi when the circuit is open. Please explain why an open system is no good for my truck?
I ended up driving my hydraulic pump directly from the transfercase using a pto from an M543 which is fulltime however I also installed an oil cooler in the hydraulic circuit at the return side before the filter and reservoir so I am not getting overheating of the fluid and without a pressure demand on the pump there is not a big draw on engine HP when driving. Will try to get some photos of the install soon.What ever came of this thread? Is there more current ones on this issue?
Does anyone use their truck for a power source for fixed equipment (like a sawmill).
