PTO Hydraulic Pump for 78 Series? (1 Viewer)

[SimonInAustralia]

I plan to put a rear winch in my Troopy eventually.

Am considering using a hydraulic winch.

Would prefer a PTO hydraulic pump, rather than tapping into the power steering pump, as I assume that a PTO pump would be more powerful and possibly more reliable.

Any idea what I need to get a PTO hydraulic pump working on a 78 series Troopy?

I came across this on the web, am wondering if 1500 Euro seems like a fair price, and if there are cheaper or other alternatives...

Thanks.

It can be difficult to find a pump that will work int he RPM range you want to use. I chose Prince and ran a driveshaft from the PTO to the pump which I mounted over the rear axle. If I could do it all over I'd go with a large engine mounted pump. It would allow me match wheel speed to winch speed. My hydraulic winch wants 11 GPM at 2500PSI.

Thanks for the advice.

I also eventually wanted to fit an Endless Air (air conditioning pump as an air compressor), and don't think there would be enough room in there for that along with an additional large pump for the winch.

Might have to go with an electric air compressor then.

So there is no way of regulating the pressure when it is a PTO pump, and the pressure is related to pump/transmission speed?

And having the pump run off of the engine would give it a more stable operating speed, compared to using the clutch to try and drive it as well, which would mean varying speed of the PTO pump depending on what the clutch/transmission is doing to try and drive with it, is that correct?

Thanks.

They are more powerful than most electric winch set ups,but you can always go bigger with anything.
The quality electric winchs are fairly reliable at half the price and I bet the total set up weighs less than its hydraulic counterpart.
Good reasons why the PTO is becoming redundant.

If you still want to go that route,Im sure local industry will have something like that.
There is also the electrically driven driven hydraulic pumps used on landcruiser tipper bodies and Hiab type cranes.
This means if you can operate it when the engine is knocked out until the battery dies,of course,you can do this with an electric wich

Dont they have some kind of adjustable flow control valve?

Yes, but space is pretty limited when trying to fit it in behind the rear chassis rail, so a more powerful winch in a smaller package would be useful there.

I thought that a hydraulic winch driven by a PTO hydraulic pump might be more user friendly to the solo wheeler in a recovery situation than a direct mechanical PTO winch.

Still not sold on the idea, just trying to get my head around it all to make the right decision.

Oops,didnt see the "rear winch" bit.
There is also the portable electric winches you can attach to the side or rear,of course they are not as powerful.
The lack of power could be overcome with a 3+2 purchase which would multipy the pulling power by 5x less friction,slow but effective.

Seems like a good idea to install a rear pto winch...


,,,your pto output must have both front and back to the driveshaft winch.

Many PTO have ONLY output in the front for the winch driveshaft winch.


A drawback may be the path of the rear driveshaft, but anything is possible

It isn't too hard to reconfigure a front facing factory PTO to have a rear output. The Thomas one I used to use was very easy.
