I'm scratching my head trying to think of a transfer case with a PTO output that is driver's side front output and centered rear output.
Any such thing?

I'm thinking that a 203 or a 205 would be too big for a YJ. Anyone know better?
I know that Dana 18s had PTOs... Did Dana 20s? Maybe the early Bronco version - which would be driver side...
Did Toyota ever have PTOs?

I was thinking about powering a gen pack or other winching duties around the property versus wheeling typing winching. For use as a workhorse a capstan winch might be more practical.
I dunno, I'm still just thinking.

I have several classic Bronco Dana 20s and none had pto's not do I see how one could be attached.
AndClassic Broncos only came with 3 speed standards (on the tree) or a C4, neither of which are capable of running a pto.
Ony way i can see is with a T18 or 19 or a 203/205.
What tranny are you planning to use? If auto you need pto capability on the T-case. If standard, ZF have pto covers on both sides. Not sure about NVs but they must as they came in 1 ton dump trucks and such.
Also the T-case (Dana 18?)in Willys trucks/wagons have pto. I may even be able to get you one. But I am uncertain of their boltpattern on the tranny end.

Thanks Dirk.
I'm planning on using a 700R4 so the t-case would have to provide the PTO port.
From what i've been reading the EB Dana 20 and Jeep Dana 18 share the same bolt pattern.
Supposedly the EBs were capable of PTO out on the t-case. The PTO in the link above is intended for an EB Dana 20. There were two different very minor variants of the Dana 20 in the EB. One was 2.46:1 ratio and the other was 2.3x:1. Whether this ratio change marks the difference in a housing and the availability of a PTO port I don't know. I've never seen a EB Dana 20 in the flesh and up close but I know the Dana 20 under the CJ7 behind the barn definitely does not have a PTO port. I'm just starting to dig into it. Sometimes researching this truck stuff borders on archaeology. "4x4 Archaeology" LOL
I'm trying to avoid a Dana 18. For my intended usage I don't want to have the extra gears running and consuming fuel when in two wheel high range. That's why I'm chasing "SWB Jeep scale" centered rear output transfer cases.

Btw, if my memory is correct, NV4500 has the PTO output on the passenger side. Ahh, crap, memory is getting muddled. At any rate - it definitely has a cover plate on the side for PTO.

I'll try to snap some pics of dana 20.
My NV4500 has panels on both sides and the only use I can think of is PTO.

Dana 20 pto adaptor (Jeep)
http://jeep.off-road.com/jeep/article/articleDetail.jsp?id=260338
apearantly Ramsey madea a pto for the 20 and Koenig made one for the 18.
The "problem " with the Dana 18 is that the front and rear output shafts are inline with each other, ie. both are down low which makes the rear shaft offset from the rear diff. I believe this is why the Willys and Jeep had the diff offset on the rear axle. Using this T-case on an axle with a centered diff may cause excessive vibration at higher speeds.
The PTO on this case is found at the rear inline with the input. this is similar to Range rover or land rover PTOs. In the same place modern t-cases have the rear drveshaft connect.
Other Dana 20 PTOs I have seen while searching replace the access cover (large flat plate, bottom of T-case) with a cast iron unit that a "regular" pto (Chelsea type) bolts to.
Since you are running an auto, the 18 may be a good option for you. they are small but quite strong and you can get low range gears for them.

Would a hydraulic set-up be another option ?
My Dodge Service truck out west had a hydraulic pump added to the acc. drives
(running off the serpentine belt.) - It ran a hydraulic motor for my air compressor.
It used the same style of electric clutch as an AC comp.
So you have minimal drag on the engine when it's not running.
You could have some quick couplers on it,
and run other hydraulic tools - log splitter, snowblower, pumps, winches...
You get the idea...
I had originally thought that a pto running off the tranny would have been a better set up,
it certainly is more common for tow trucks and the like.
But, it did keep the underside of the truck a lot cleaner.
And that was a good thing when doing service calls on logging roads
my 2 cents anyway...

Thanks for the link Dirk. Not sure why I didn't find that one. Now I'm half tempted to go out with the shovel and start digging under the CJ to have a look. Err, maybe not tonight.
Gerry, interesting idea about the hydraulic setup. I'd definitely have lots of room in the engine bay for something like that. I'll have to do some research of that. Just thinking out loud, maybe I'd be better served by just running a gen pack off the accessory drive. Might be an expensive fix if I get the Jeep swamped in a mud hole though. Makes a case for hydraulic.

This one bolts to the bottom of a dana 20 and replaces the access plate.
