i did some searching and read alot of references to winches and whatnot, but still don't really understand what it is. What does the acronym mean? is it a winch which runs off of your tranny or t-case? if so, how do you run the cable out from under the truck without hurting anything? school me.
 
power take off, it is a box that mounts to your t-case or tranny that has a gear drive in it that can drive a small d-shaft or hydro pump. most popular manufact. are chelsea & muncie.(that i work on anyhow).

can be used to drive a "pto" winch or a hydraulic pump for a dump bed, etc.

usually has a cable mounted or air mounted control to engage it. then the device it drives will have a control also.


there are 2 mounting patterns for them, our t-cases & tranny's use the small pattern ones. eaton big truck trannies use the larger pattern usually.
 
IIRC its power take off, which means it uses a t case to work.
 
SM 465 and NV4500 also have PTO ports on both sides of the tranny's. It's not just a t-case thing.

Nothing really. Unless you find one of those HUGE PTO operated Garwood winches in the larger 2.5 and 5 ton military trucks. :eek1:
 
ok, well i'm going to take it upon myself to find a d@mn good use for one and then sell it to all of you. ;) we'll see what i can come up with!

Yeah, your just getting creative on coming up with bucks for your new transmission. :D
 
nah, the money side of things is not the concern for this swap - i'm getting an unbelievable deal, it amazes me how good this deal is. but i have a hard time with the concept of leaving well enough alone. :) if it's got the possibility of some constructive use, then it's going to be put to some constructive use. :D
 
well, i'll send you a free one just b/c you went to the same school as my wife, only in a previous millenia. :wink1: so don't be too upset. :D
 
A good use for a PTO is to run a hydraulic winch. A Chelsea PTO hooked to a small gear driven hydraulic pump. Most parts you could scavenge off of an old tow truck...

lots of trannies have PTO opening

including the 420, 435, 465,
and transfer cases and other stuff

use them to operate dump beds, roll backs, plows, etc

they most comonly drive a pump which is used to move cylinders in the above and other applications

on a k5 i dont knwo what you could do with one other than a plow

thats about it really



good luck
 
u could build a hydro margarita blender big enough to supply everyone in camp, in fact u build it, buy the liquor & i will meet up w/ u to drink.
 
well, i'm not much of a drinker, but if that's what the market demands . . .


rene - how would you keep the cables out of your running gear/engine/body/etc?
 
so i've been considering the aforementioned invention quite a bit recently, and realized that i don't have a d@mn clue what i'm working with. :D it would seem to me that such a contraption could only be run off of a truck in motion (or at least with wheel spin), as this is the only time the gears in a manual tranny or t-case are moving. is this correct?

that might limit my imagination. :( but its ok - i'll still invent something super kick @ss, so don't fret, be assured, the gears in my head are spinning. i will have something which will make you want to give me money (as i know you are all so eager to do). :haha:

for the transfer case ptos that is corect but one off the transmision will spins unless the cluch is engaged

so you could potentially run it in neutral or when the vehicle is moving, correct?

Yeah so on a tranny, where is the pto or gear located? If your saying the clutch has to be engaged, would the pto spin fast if you were in a higher gear? Like put the t case in netural and then put the tranny in 4th. Does anyone get what Im saying? It probably doesnt even matter how fast in spins.
 
i dont think it maters what gear it is in because the transmission can be out of gear and the pto still spins when you let off the cluch at least thats how it works on my grandfathers bucket truck
