Steering pump powering hyd sys

[MKeeney]

I have a 99 PSD and I'm going to put a hydraulic dump bed on it. I also want to install a large hydraulic winch, (18k). The dump bed from P&J comes with it's own crappy little electric motor driven hyd. pump, but with the load I'll be carrying I would likely burn out that pump pretty quickly. The winch requires a significantly higher GPM rate than the dump bed pump can provide, so I have to run it off the power steering pump. Two different systems now. I spoke with their P&J engineer about using the power steering pump to drive both the bed and the winch. He didn't have a problem with it.

So, my thinking is to bolt a tank on the frame and use it for the hyd fluid reservoir. My concern is, will the distance the fluid has to travel to get to the steering pump screw up the steering performance? I don't think it would, but it's always better to ask. Anyone got any opinions?

I'd question the actual volume the PS pump puts out and how fast the bed would raise and how fast the winch would run. You can buy hydraulic pumps that have a clutch pulley setup like the A/C compressor that you can turn off when not in use. Might be better to go with a setup like that.

I would definatley get a belt driven PTO like a wrecker has. Try to find an old automatic tranny wrecker and it should have one.

Is there enough room in the engine compartment for one of these things? I'd sure like to see what one of those looks like when it's installed.

It's not that much bigger then an ac compressor. If it even is

Sounds like that guy at P&J engineering really wants to sell that dump body. What you need is what is called a "live hydraulics" pump. It will mount in your engine compartment with no problem. Yes you will need to have a hydraulic oil tank (mount to frame rail under dump body), and leave the power steering as is, it shouldn't even be figured in the configuration. You will have to do a little plumbing and wiring. The pump will have a switch in the cab to turn on the pump, as stated above, lke a a/c unit. It is a electric clutch setup just like an a/c unit. That live hydraulic pump will have enough psi and volume to operate both your items with no problem. Don't forget to include a filter for the hydraulic fluid.

Well Holy Moly, there is such an animal.

It's about $1,700, but it would do the trick.

Thank you for suggesting it. I had no idea such a contraption existed.

Here's one from Northern Tool, but you'd have to fabricate the mounts and idler setup: High Pressure Hydraulic Clutch Pump — 2.32Cu In. | Pumps | Northern Tool + Equipment

Also check out "Hydra-bed" and "Bester" Hydraulic Round Bale Feeders besides Deweze... I've used the bale movers more than I'd prefer the other two over the latter.
RPM range is from 700-1700.

Have to run now, but when I get home tonight I'll take pics of a pump installed.
You have a E99 or later model year?
