Hydraulic winching in the fzj-80

[Mudmountain]

Is there anybody out there with experience in the setup of hydraulic winches in the Fzj-80 chassis? I have a '97, which does extensive recovery work, logging and quarrying in remote areas. The electric winches seem to lsck the appropriate stamina for the kind of extended use required on these jobs. As there's no PTO on the 80-series trans or T-case, as far as I know, at least, I'm led to wonder how much modification would be neccesary to run the Mile-Marker winches on a 'cruiser without resorting to GM power steering equipment or other such mods. The stock PS pump puts out the minimum pressure required to run one of these things, and the techs at AGR weren't too confident about rebuilding a Toyota pump and gearbox to handle the increased pressures generated by Mile-Marker's little hydraulic motor.

Hydraulic is definitely better than electric for extensive work such as you do. However, PTO is still better. There are a few options out there to mod 80 transfer cases to accept a PTO.

Not easy or cheap, but it could happen if you really need it to.

To make it easy for yourself and keep the price down, I would recommend a belt driven pump. Like http://www.flowfitonline.com/acatalog/FLOWFIT_MECHANICAL_CLUTCH_AND_PUMP_ASSEMBLIES.html
Small and nice package to a fair price

How is that mounted to the 1HD-T?

Your reasoning is flawed. The MM motor does not create any pressure.

The pressure is provided by the power steering pump and most PS pumps put out pressure in the 1000 - 1,100 PSI range, so all of them will provide the required pressure to run the pump. The problem with using a PS pump is that their volume is relatively low and this limites the speed of the winch to relatively slow speeds. If you get a higher volume pump, you can run at higher speeds, but these require more power to turn so you might need to have two or three belts to do the job in a belt driven pump. A PTO driven hydraulic pump would do the job, but is more expensive than a PTO winch.

same spot as is in the 1FZ-FE but 1HD-T have the vacuum pump in the back where 1FZ-FE have just clean cap ..

One of the Icelanders was running a Runva hydraulic with a reservoir for extra fluid. He seemed to have no issues while winching, but again had increased his fluid volume.

I believe he is powering a separate hydraulic pump attached to his PTO port on his transfer case. His transfer case came with a PTO, being from Iceland, they have access to such things.

sorry, guy I was thinking of was from Norway:

Mudmountain, I'm running a 10,500 lb mile marker hmmv winch on a 60 series using the stock power steering pump. In these applications, the pumps output pressure governs the winches capacity ( pounds pull) and the flow rate governs the speed. And don't forget that power steering pumps are designed to produce a higher pressure at slower speeds, so just set the engine at regular to high idle.
The pump is under rated to the winches maximum rated capacity, so in my case, I get a which that is slightly slower ( but 2 speed so no problems for a quicker rewind) and has an 8000 lb single line pull. And because of this it's running easier and has a better safety factor on all components.
Go ahead and fit it and use it, it's a good rig!
