I guess I'd probably start looking at how to flip it's input so I could make it work with the PTO I had.

have fun spooling all that cable.

I have a passenger side PTO coming, winch flips easy, I need to package the shaft from the PTO to the winch around the front output of the transfer case. Sorry if that was confusing?

I was confuzzled.

what about a chain sprocket directly off the PTO shaft so you can move the shaft that runs to the back further towards a frame rail, or up in between them above the case?

Happens!

Not a terrible plan. I'm thinking going over the top will have a lot of problems. Thinking down low will be simplest, but once again needs pretty rugged protection/armor around it.
 
well I was thinking all the way to the inside of the frame rail, then back along it.

I guess the only concern there might be frame flex wasting hard mounted pillow blocks. Some fat rubber mounts and bolt pillow blocks to the frame rail with a shaft running down it? Straight or humped frame?
 
Hydraulic?? Drive a pump off of the PTO and use a hydraulic motor on winch. Obviously the hoses can be run in places that would be much more convienient than a driveshaft.

Why the **** didn't I think of that?

I have a PTO winch sitting around and that's exactly how I am planning to power it. :homer:

For me it's cost, although I found a hydraulic motor in my fathers garage yesterday from a Ramsey winch.

This is a hobby rig that I'm not looking at dropping huge coin on something ill use a handful of times a year

Random P/S pump, lovejoy coupling, scrap metal bracket and a motor you had on the shelf aren't gonna be any more expensive than shafts, bearings and couplings/chain.

The hydraulic solution will probably tolerate sitting a lot better than the mechanical solution will.

Ok so a rough check says the motor I have wants 1600 PSI and 15 GPM, according to the Billavista Hydro steering article "Depending on the exact model of the pump, "P" style saginaw pumps are rated for anything from 2.4 to 3.5 gallons per minute (gpm) flow and 1100-1450 psi pressure."

Tell me how great that random P/S pump is going to run the motor I have :rolleyes:

Bypass the flow control valve and a p-pump makes 15gpm at 3600rpm.
 
From a cost perspective, I would say hoses will be the big ticket items.

I actually have been thinking about hydraulic winches lately myself. I would run a pump setup that could be disengaged when not needed, like from a PTO gearbox or if room allowed, a setup driven right off the front of the engine crankshaft that could be diengaged with a simple dog clutch. Lots of pumps to choose from at surplus center.

PTO isn't going to spin that fast, and if I engine drove the pump I'd need a 12" pulley to spin it that fast. Neat that its possible.

Thoughts on this thing? Would serve multiple purposes on the farm, but I could throw a couple of hoses with quick couplings on the hydro motor I have when I want to use the wrecker
