PTO Winch
I have discovered a pto winch setup from a seventies international scout. I was wondering if anyone had put a PTO winch on their dentside. I was also wondering how adaptable they are to different transfercases. I don't know what kind of case Scouts have, but I would assume it wouldn't be a 205. Any pics would help. Thanks.

I thought about doing this.
U have heard the PTO outputs for the 205's are semi hard to find.
Also - would you go with a hydraulic drive or a driveshaft? I think it would be pretty hard to get a straight enough shot to run a driveshaft.
Either way - you can make a PTO winch run off the 205 - you just need the correct output.

Yeah, I've had some thought experiments on this as well.
I thought the PTOs were all the same standard size (based on the number of PTO cover bolts) governed by some industry standard PTO specification?
The only one I've seen is on a 70's F350 tow truck, were the pto was attached to the NP435 trans. The pto unit itself was really small and it had a small driveshaft which turned a hydraulic pump, which powered the winch.
Anyway, I'm just sharing. . .

I am ust finishing up putting a pto winch on my truck (79 F250) . It is a 10K (probably more like 20K) garwood winch off of a military deuce and a half. (M35A2) Anyway I made custom mounts out of 3/8 plate and 6" heavy C-channel to mount the winch behind the cab directly in front of the first bed crossmember. The mount utilized both the sides and tope of the frame. I bought a NP205 PTO unit off of someone in Pirate4x4 forum. I can power in at four differents speeds using the trans, and also power out, plus the winch has a load holding brake up to 10K I believe also. The cable runs out the back of the truck through a custom fairlead mounted under the frame, although I might change this as it hangs kind of low, and My truck is only on 36"s.
Anyway, the truth is that most 6 bolt pto's can be adapted to work with the 205 case with just a gear swap....if you want more info on this just ask. Also, you can get reversable pto units for the transmission if need be also....

What would be the easiest method to installing a pto winch on a NP435/205 setup? What's the difference in installing it on the transmission or on the trans case? Do you have a picture of your setup? Thanks!

I can get some pics but by the time I get home its dark out already (damned daylight savings) but I'll see what I can dig up.
The easiest way would be to find a single gear pto unit to fit on the transfer case. This way utilizes the transmission to control direction of the winch. Basically put the transfer in neutral and pick what gear on the tranny engage the pto and clutch and away the winch goes, either forward or reverse.
In order to place the pto unit on the tranmission and still have power in and out, you would need to get a unit that has a reverse option. These are more expensive and harder to find. Usually pto's mounted on the transmission would power a hydraulic pump, therefore only need to spin in one direction.
To add to this confusion, there are multi-gear units that can increase torque output or speed etc...
I have the simple setup, as do many others and it seems to work fine.

So then the PTO unit only has one control; engaged or disengaged? So you have a driveshaft that goes from the PTO unit to the winch? Which means that your winch has to be near and in-line with the transfer case, to keep the driveshaft straight and simple? And I assume this way would also work on an auto trans?
Yes, please post lots of pics, whenever you can!

Yes, I have a driveshaft from the pto output to the winch input.
Yes, if you run the pto off of the transfer case you can have and auto trans.(some newer autos have pto provisions though)
People have run pto winch with using chain and spockets when being inline is not obtainable.Also, using pillow blocks along with several u-joints, one could vastly change direction of the pto output if you get creative.
Yes, for most pto it is either engaged or disengaged. Unless, you have a reversible unit as stated above, where then you would have f-N-R choices, or possibly two levers with engaged/disengaged, then F/R..depends on setup. Also, there numerous types of engagement methods, levers/cable/air shifters...the list goes on..but it isn't that complicated I promise.
Like I said I will try to get some pics tomorrow.

My 77 F250 has a 12,000lb Ramsey PTO on it. Run by the NP435. 1st gear is loads of torque but way too slow. 2nd gear is usually best.
Gotta be careful when using a PTO winch, they have way more power than an electric winch. You have to watch them all the time. My truck's PO warned me about this... and for a good reason. Look at the top of the fairlead... it was done simply tightening the slack in the cable.

do you have a reversing pto with the np435, or is the winch itself reversing?? I was just wondering what do you do in the event that you need to release slack on the cable while it is still taught?
Oh yeah, if that is a 12K rated winch, then the one I have is grossly underated. The width of the winch alone is about where the framerails are!!!!

So what I am gathering pto winches are not necessarily specific to a particular vehicle, its just finding an output that will mate up with the transmission, and building the driveshafts to reach the gearbox on the winch. Correct? So, buying a winch designed for a scout wouldn't be a bad idea.

you pretty much got it. PTO weinch's can run on anything with a PTO.
Personally I'd look at a hydraulically driven one to avoid the whole driveshaft mess - but then again I went with an electric instead of a PTO driven all together...

You can get a hydraulic winch but still run it off of a pto. Eventually that's probably what I will do for the front of my truck off of the transmission. The difference with the hydraulic is that u need a pump, tank, and lines. I used to have a hydraulic that was run off my steering pump and it pulled strong! Hydraulics are also good because you can remote mount them with quick disconnect fittings on the hoses
