good to know about the ARB. These winches do look much smaller than the electric ones with same rating.

So, besides the shortening of the hoses, the little adapter kit for Toyotas was fine, and all connectors fitted OK?

well, is the PS pump big enough? :)

The adapter kit worked just fine. I ran the hoses through the crossmember under radiator so you might want to measure those holes and soruce some grommets as I did.

I just haven't had time to do any testing and I'm not sure how to go about it as well. Withg spring comes all the maintenace that I ignored over the winter and I now have 4 vehicles to watch so things have been busy. I'll try and get to it as soon as I can.
 
Very cool-you may have the first Hydraulic winched 80 series in the USA. Your set up looks clean and well done. Nice job, and how about a few more pics of the hose routing and connections. I'm curious exactly how it interfaces with your PS system.

It's plumbed in in line. You remove the highpressure line from the pump to the gearbox and toss it. You then run a high pressure line from the pump to the winch and then a high pressure line from the winch to the gearbox. After the gearbox things remain the same.

I'll get some pics up as soon as possible.
 
can't you pull some rocks or a stump or something? :)
or winch yourself up a dirt hill? :)
 
I took some more pics today to kind of wrap things up to date on the install.

Attached are a pic of how I mounted the instruction plate to the inside of the ARB support. Basically you drill 4 - 1/8" holes and drive in these twist rivets with a hammer.

The other pic is of the control box. I decided to remove one side of the box and then mount the box to the upright by drilling 4 holes and screwing the box to it, basically using the support as one side.

From some recent discussions I'm going to look into expanding the PS reservoir tank, so if anyone has a line on a used one I'd appreciate some help.

Did I miss somehting here or did we not get a review of how it pulled? It was like reading a suspense novel and the last page was missing.
 
Sorry, there was another thread at the time going on the hydraulic winch and I must have posted it there. I yanked my wifes 4Runner several times up a hill in high with no difficulty at all. I had the engine's hand throttle set at 1500 rpms and it pulled the 100ft line in, in 3.5 minutes.

While this is slightly off the mark as far as the specs go it coincides with expected performance from our PS pumps.

Christo has since designed a new bumper which won't except the 12k warn but he feels it's overkill for the 80 and 9k would be suficient. This 12k hydraulic on our PS pump is probably in that range at a great savings in weight.
 
and no adverse effect on PS or fluid seen so far, right?
 
Actually if you bolt it on upside down it will work fine even underwater.

While MOST of the cruisers here dont spend much time upside down (cough christo cough j/k) they dont like to work in that position either esp submerged and inverted.

I have been around helicopters with both hydraulic and electric winches. I bought a hydraulic..

I think in the short term I can get done what I need to with the 9k MM. The line speed is better on the 9k since the motor cu/in is smaller..

I know some guys who specialize in aviation pneudraulics.

Got a feeling we can get a bit more out of the oe pump than it is setup for. I also feel that given its drive system I can also come up with something to make everybody happy with some R&D. A pair of pumps stacked on a single shaft that is driven and mounted just like the stock one.

The second one would be a variable geometry vane pump.

Basically set up to back off pump volume to maintain a set pressure.

I will also figure out the mfg then model and finally get a data sheet for the motor on the winch. Really have a feeling it is good for more than 1500 psi.

While it may seem like a Tim Allen thing to soup up a winch I am not doing it with out some help from hydraulic pros.

I've been looking into this a little as well. The stock vane pump is extremely durable since the vanes wear as needed to give the pump it's long life. However since the sealing action of the vanes utilizes centrifugal force at idle RPMs the pump's ability falls off sharply. For a vane pump to achieve better flow at low RPMs springs are usually added to help the vanes to seal better.

With a donation from another member I have a couple of used stock pumps that I was going to look into modifying and also making an adapter plate to utilize a better gear pump for flow and pressure.

I'd be interested in any help identifying said pump for our application.
 
We would need either a 2nd pump for two systems or plumbing the gearbox with a pressure reducer .

The best solution is two seperate systems. The variable geometry pumps I am thinking of seal just fine at lower RPM. Dirty fluid will kill them so filtration needs to be included just like on my aircraft. Filters on both the feed and return. Even fluid coming from res needs to be filtered. We run 1 micron filters..

Really accurate measurements and illustrations of the pump would help considerably in finding an upgrade.

Oops a buddy just reminded me that he thinks we need a rotory vane pump for the ps system and an Variable Axial Piston Pump for the winch.

Oh and if you put an acummulator in the return side and use it also for extra fluid volume instead of a res it WILL work upside down.

I just bought a tow rig with the MM 12k HYD, very nice setup...smooth two speed operation with the stock Dodge pump. I think it will do great on the tow rig since it's always wheels down...well at least I hope it is.

You would be the best judge of your chauffeuring ability and if you have a pre-disposition for toppling your rides them by all means stick to an electric.
 
Hey Rick, just wanted to get an update about how you are liking your hydro MM set up. I've been reading up a lot and have been getting the parts together to upgrade my p/s reservoir capacity, cooling and filtering. Even though I would love to add another electrical device on my truck, the thought of saving weight, having a simple install with very few components plus being able to operate it under water are enticing reasons to go hydro.
 
it's been working flawlessly. I've set another one up since this thread. The only thing that gave me some trouble was when you switch from high speed to low you need to spool out a little line for the gears to change. If you don't it will stay in high. I've also switched to synthetic line which saved even more weight.
 
Runva 12K hydraulic winch

I also went hydraulic and didn't want to go the 2nd battery route immediately (will do so later for camping and other uses)

I put in Runva 12000 Hydraulic winch two-speed and pretty pleased with it. It did not come with the MM fittings per the Landcruiser so I had to get the hoses etc. made up and had some initial leaking issues (wrong type of 'washer')

May upgrade with a replacement power steering cooler (like https://forum.ih8mud.com/80-series-tech/456458-power-steering-cooler-upgrade.html
) If I find I need to.
 
Alot of talk about winching when upside down... Now I'm yet to roll my truck but why would you winch it around whilst upside down?

Why won't a hydraulic system work upside down (apart from the fact that the engine wont be running)?

wouldn't the precharge in your accumulator be greater than the pressure in your return line, sealing the fluid port?

I like the idea of using an accumulator. Placed just after the pump the flow rate would not be so dependent on the engine rpm
