It would be possible but it is also possible that the power steering pump wouldn't have the capacity to run it.
Our previous 4wd was an ex USAF ex Desert Storm Humvee which I converted to RHD, fitted out with all the necessary equipment and we travelled extensively for over ten years in it.
The Humvee and H1 had the same braking sytem with a hydroboost, the only difference was it had a Saginaw pump which had a higher flow than the one in an Oka.
One of the other Aussie owners tried a hydraulic winch tapped into the power steering system and it resulted in no brake or steering assistance when the winch was operating as the pump couldn't supply enough so I suspect that the same would occur on an Oka. Fitting a higher capacity pump took a bit of doing and depending on how much winching etc you may possibly need a cooler in the system as well.

The pump for the HYD winch bolts to G/box or T/C

20 000lb stronger than electric but heavy
mechanical drive winch is another option, 25 000lb

Looked into it. They're incredible! I bought the tranny pto and pump second hand (in storage now) but when i realised i needed a roughly 75 litre hydraulic tank or a smaller one with cooler and lines running everywhere (remember control valve levers etc) and then saw an M15000 Warn winch on ebay for $700 instead i thought why bother... Packaging is easier and overall much lighter! You definitely need to run a separate hyd pump, the flow rate of the steering pump isn't adequate. Also, remember airlines/cable to pto. The whole thing ends up quite complex which is something i wanted to avoid with my build, maybe for a commercial application but i decided against it for the few times i needed it.

Cheers, alister

374 apparently had a hydraulically driven generator mounted beside the transmission with the hydraulic pump driven off the front of the crankshaft when in service with the RAAF.

Ruedi & Susi have removed the PTO driven hydraulic winch from NT001 to reduce weight.
It is a complete package (including 40 litres of hydraulic oil).
It is possible that they may fit it to their other truck, but last I heard it was available at a very competitive price.
.....but it is in Germany......

Cheers, Peter.

Hey, thanks for the thought, but it is sounding like the 12 volt option is far better course to take?

average OKA 6ton
trailer 2ton
suction / drag +3ton

15 000 lb winch = 5.8ton

good to pull Jeeps out of the shit!!!

? what are you going to winch from.

Brett you would know better, but if you use pulleys etc, does this not double the capacity it can do??

I get that you may need to find a fairly hefty tree etc.

Brett, ummm 15000lb = 6.8T ;)

Of coarse, suit the winch to your application but yes OBJ a snatch block doubles this to 13.2T (i carry a snatch block but haven't needed it yet) but of coarse a tree would need to be the same size whether you had a hydraulic or 12V winch. Snatch blocks also obviously halve the line distance. In Vic we have trees to winch from, that's obviously not the case in some places. 12V have their limitations but for most (all those not towing a 2T trailer while traveling/4wding) i believed a M15000 Warn winch to be adequate (especially when you can pick one up for not much! ;) ).

Cheers, alister

I reckon I have put this up before.....

Warn 16.5Ti with an "extension cord".
Can be attached to pull from anywhere on the vehicle.
Has a mounting frame attached that allows it to travel up front in a Hayman Reece style hitch.
Works well because the winch always 'points' in the direction of the pull.

I also carry a 50m extension and 2 snatch blocks.



When there are no trees, digging a hole for a spare is an option (if the tide is not coming in...).



I did not actually get to use this one because a big tractor showed up first. :)

OK Peter, I'll bite. How do you get the 85kg wheel out of the hole when you've finished?

If you pull it from the opposite direction, the rope going over the lip if the hole will lift it out. That is why the "T" is required on the other side.
Alternatively, I have a spare wheel winch if I can back up to it..... :)

ps...only 80kg......

More digging. :(

I drove 3 star pickets to ground level to get a 'cruiser out of a bog in a paddock 25yrs ago. They are still there and are now a tyre staking hazard

I have a rough idea where there is a Toyota split rim and tyre along with a wheel brace and a 4m steel cable buried to this day in a trench just like the one in Peter's picture, as the tide was coming in rapidly and it appeared to have headed for the centre of the earth in the blue grey mud underneath the thin crust on the tidal flats south of Cape Leveque it was left there. There was only the eye on the end of the cable visible so it was a long way down!! We couldn't locate anything solid with a 6ft tent pole!
