Engine/Transmission (1994 - 1998) Help...trying to figure out if I can mount a PTO winch to my 5spd??

[Coalsmoke]

I'm trying to figure out if I can mount a used Chelsea PTO winch to my truck. What I know about the winch:

-chelsea pto winch, 8000lb comes with 2 pto units one with forward and reverse

-on the chevy trannys there is a plate held on with 6 bolts, the pto unit bolts in there. one pto unit does whatever your transmission does reverse makes it spin backwards the forward gears make it spin forward. the other one has forward + reverse so you can have 4 forward gears and 4 reverse



I have tried to gcross reference with Chelsea products but I keep going in circles (that company needs some serious help with their lack of aplication guides).



Anyways, my main question is, does anyone know if these gears will be somewhat standardized and possibly mesh up or is it a different set of PTO gears for each different transmission?

It is my understanding that the PTO attachment points on all transmissions are standardized. Of course, I have been wrong before...

PTO units are somewhat standardized but not universal by any means. If the PTO units were on a Chevy NV4500 transmission then I'd say you are in good shape. Sometimes a spacer plate is all that is required to swap from one transmission make or model to another. I'm working on a similar project for my 95 and talked to the folks at Factory Direct PTOs and Hydraulics. They handle Muncie products and were the most helpful of all the people I contacted. I don't know if they can help you with the Chelsea info or not. Their web adddress is: www.ptohydraulics.com.



As a side note, it's my understanding that a PTO mounted on the transmission runs at one speed (changes with engine RPM of course) and in one direction only, i. e. changing gears has no effect on PTO output speed or direction. When mounted on the transfer case, changing gears in the transmission does change PTO output speed and direction. I'm looking at a unit for the transfer case for that reason. Someone please correct me if I'm wrong.

This has mirrored the experience I have had with PTO driven attachments. If you mount them to the transmission and they don't have a reverse mechanism of some sort built into them then they will only turn in one direction. Most of the PTO winches that I have seen have a gear box on them that allows for forward and reverse, since the PTO only turns one direction.

shoot, so since I only have the NP241DLD transfer case I don't think I have that PTO port like the DHD has, only have ports on the transmission, but it won't do me too much good if I can't use my transmission to control the gears if this winch is geared slow as mississippi mud. Of course there is another challenge, getting that shaft from the transmission up to the winch at the front bumper. Actually, the only thing this winch has going for it is the price and the fact that I keep hearing how PTO winches are tough and will go ferever. But all of these install issues might not make it worth its while. Maybe I should just go with a Warn electric.

I too am in the same boat. I have a 20,000 tulsa off a 70's chevy C-70. I want to mount it on my np203 on my 77 pw, but cant get a def answer if all ptos are standard. I have messed with them before, but never one this big. I think they are all pretty much standard, though.

Oh yeah, I had one on a transmission, it wasnt any good. you need to be able to gear it up/down if need be. I am actually going to try to mount mine behind an auto and see what it does. My guess is the auto will smoke eventually, but well see.

You are correct about the transfer case. Only the DHD has PTO capability. I have a Braden MU2A that I am going to put where the spare tire is under the bed. Running the drive shaft to the rear is a lot easier than trying to snake one up to the front. As for the front, I plan to put a hydraulic winch there. A transmission mounted PTO running a hydraulic pump will work great for that. Getting flexible hydraulic lines to the front bumper will be a lot easier than trying to route a PTO drive shaft up through there.

 

[Coalsmoke]

I'm kissing the pto winch goodbye. After close inspection I see that there is no room for the shaft to be run up through the front. I thought for sure it could be snaked in, but no go. Thanks for the help.



PS, the rear looks plenty clear, good luck.

PTO's are frequently not interchangable, some (like the 241DHD t-case and many older transmissions) use straight cut gears and others (the NV4500 and many other transmissions) use helictical cut gears. PTO's also come in different ratios depending on the trans or t-case drive gear size and speed and the desired output RPM, they can be clockwise or counter-clockwise rotation, they can be a right side or a left side mount. Some transmissions will require a completely different type of PTO on the right side than the left side, sometimes straight cut on one side, helictical cut on the other. Since a PTO drives off the counter shaft on the trans and the main shaft on the t-case they end up turning opposite directions and this needs to be addressed when ordering a PTO. something I noticed while inside my t-case, the gear turns the same speed in neutral, high, and low range. Truck outfitters are usually a good source of parts and information on PTO's.

An option might be a hydraulic winch and a PTO driven pump.
