Thread: Hydraulics and the Isuzu

Mal Storey/Maxi Drive used to make and install pump kits for hydra winch use.

One day I'll scan all the info I have (ex-Maxi Drive) into the docs section here.

I have been toying with the idea of a PTO driven hydo set up to operate a lifting jib on the back of the county and maby a winch as well

Hi all

If PTO's for the rear of the transfer box were easily obtained, the torque available to drive a large pump would be ample, but finding a suitable PTO is difficult as they are not a common item, I am not sure if the Maxidrive arrangement is still available.

So I am currently investigating running a hydraulic pump on the front of my Def 300TDi engine using the electric clutch from a air conditioner compressor for disengaging the drive.

A power steering pump from a large truck should give the oil flow required, but it still needs to be able to maintain a suitable working pressure and have the ability to attach a larger oil supply as most power steering pumps only have a small reservoir.

The other two issues I have at the moment;
Is there enough room to mount this type of pump?
And is the strength of the multi vee aircon belt enough to transmit required torque to a pump, although this may be overcome by a reduction in the speed (rpm) after the electric clutch?

the uses I have in mind for the oil supply are;
a tipping tray,
replace the electric motor on my warn winch, ( I believe that there are kits already available for this purpose. ),
jacks for leveling a camper,
remotes for running a log splitter etc.

Has anyone already done this work?

Cheers Arthur

You'd have to ring MR Automotive to see if they are making the adapters.

Maxi Drive used either one of six Cross pumps or a variable displacement Volvo pump and made the adapter to fit the PTO takeoff of the LT230, usually direct coupled off the back, but could use a chain drive that Mal used on the forward PTO arrangement to then drive whatever.

Ooh, that was a nasty sentence

Oh, and the Volvo pump and motor were made to drive a high mount Warn winch, supposedly capable of 17HP (the photos on the sheet I have look like it's on someone's winch challenge vehicle)

mile marker do hydraulic winches, been in uk for a few years and even longer in usa.
they give some good points about using hydraulic winches, but its a bit like the v8 petrol v's diesel arguments they all ahve good points good/bad experinaces

The Isuzu MSA gearboxes have a pto port cast into the casing. This is where light tip trucks often get their hydraulic power from. But I've no idea how expensive a bolt on PTO pump will be.

It doesn't have to be PTO driven does it? I assume you could just run a clutch pump off the engine provided you don't have aircon you could just put it in the same spot.

Winch $850, Clutch Pump $500, Other stuff $300. Seems the cost isn't too bad and you'd have hydraulics in your truck so you could then get one of these!
