Before the flamers flame, I tried the search, came up with nil. Perhaps it's operator error on my part. Appologies to the Discoweb gods for polluting the webspace with a question that has perhaps been asked before.

Any known steering pump upgrades to a D1? I'm interested in a hydraulic winch, which would require higher flow. AGR makes great pumps, but I don't believe that any of them are a direct bolt-on. Any ideas, or links?

I read some threads in a search about folks using the ACE pump on a D2 for the milemarker because it has higher flows. Does anybody know if this pump referenced above can be placed at the ACE site on non-ACE D2's and used for driving the winch? Are there any draw-backs to this?

The post above does not make reference to the ACE pump, only the a ZF high flow steering pump.

Interesting.

I've seen several posts here talking about the possiblity of using an ACE pump to run a hydraulic winch. I've wondered about this too. I've not done it, but here is some of the research I've done:

My 2000 D2 workshop manual details the performance of the ACE pump:
Displacement: 8.5cm^3/rev
Operational pressure: 1958psi, 135 bar

7.0l, 1.8gal /min at 775 rpm
9.25l, 2.4gal /min at 7625 rpm

The Milemarker 9,000lb winches are rated for 3.5 gal/min at 1500psi.

Are there any hydraulic engineers out there? This sounds like it would work to me, as long as you put a relief valve in the circuit to bring the pressure down to 1500psi (which would bring the volume up a bit, yes?).


One of my questions is: Would installing an ACE pump on a non-ACE D2 (which should be easy enough, given the already in-place bracket) cause a significant decrease in milage, given the additional engine load?

IMO, mileage shouldn't drop much since there isn't a real difference in EPA estimates b/t ACE and non-ACE. But, friction is friction and there will be some loss.

wouldn't you want a pressure reducing valve set below 1500psi along with the relief valve?

Its been my experience that the ACE pumps tend to be noisey and failure rate are about average. I would look into converting the whole steering system to hydrolic assist, and then use the steering pump for the winch.

a relief valve will drop both pressure and volume because it sends fluid (volume)back to the resevoir instead of through the working circuit.

You may be able to install a smaller driven motor on the winch to produce higher rpm output with the given volume of pump output.

"You may be able to install a smaller driven motor on the winch to produce higher rpm output with the given volume of pump output."

Thom, you are correct. Keep in mind that the small cc hydraulic motor will also drop the strength of the motor as well. I chose not to get the smaller motor. I'd rather have more pull than speed. I look at it this way, here are the speed options with the MM: really slow or 20% faster than really slow. (This is obviously based on my setup & not some PTO with super high flow pump)
