Kevin, Ed,
Almost all truck type trannys have PTO capabilities. The drive unit
attaches where the sheet metal cover with 6 bolts in it is. The output
shaft from the PTO unit points to the front, or rear of the vehicle. It is
engaged by pusing in the clutch, and pulling a knob/cable arangment or a
lever to engage a gear of the PTO with a gear in the transmission. You can
leave the trans in neutral, or run the PTO while driving. The PTO is
driven off of the countershaft, so it dosn't matter what gear the trans is
in. Fitting this PTO unit to the trans should be a gasket and bolt on
affair. (very simple). If you are running a tansfer case on a 4x4 you may
be able to attach the PTO unit to the transfercase, leaving the Tcase in
neutral, and then selecting a gear in the tranny, to control PTO speed. If
you need the PTO unit that attaches to the trans, contact a local truck
parts supplier, many farm trucks use them for hydraulic lifts, other trucks
use them for pumps and such, I know a farmer that may have a few of them on
the shelf....When I worked there they had about 10 or 12 trucks with PTO's
(and some with 2) mostly 2 Ton thru Semi's. Within the next 2 or 3 weeks
I'll try to get some pics of the PTO's and how they mount...

Hi all.
A forward. Maybe someone can provide Ed with additional input. Ed's
truck is a 2 wheel drive with a PTO take-off out the side of the tranny.

Subject: pto winch
>Hi All,
I met a guy who has a PTO winch for sale for $50 (saw it at a garagesale);
it looks really strong and has lots of cable. He ran it off of a Willis
(dunno how to spell that) 4-WD and a shaft came straight off the
transfer case to the front bumper. Would this thing work on my truck,
using
the tranny's pto off the side,
assuming I someday find a pto output shaft and some 90 degree converter?
I've never seen one of these installed, so I have a poor image of how
things
go together under the truck. But I want to use my
pto -- not sure why -- and definitely want a winch because mine is a work
truck and I use it for firewood.
>Thanks,

Hi Ed.
Responding to both your E's. Though I've never seen or heard of a PTO
running off a transmission and not a transfer case, I'd think that a 90
degree bend in the power transfer is possible. How could it work? Let me
think out loud here:
The technical part would be engaging the PTO and disengaging the
driveline of the truck. You'd have to have a separate shift lever on the
tranny to do that, I'd think, or you couldn't power up the PTO without also
turning your drive wheels. You could then use your stock gearbox and RPM's
to determine the running speed of the winch, with an available reverse.
You could then have some kind of heavy duty gearbox made to handle the
torque transfer out to the winch. That could be a relatively simple
arrangement, with a general principle similar to a ring and pinion set up.
In-line: Input yoke, bearing-gear-bearing... 90 degree turn with
bearing-gear-bearing, then output yoke. I'll run it by a few friends who
are machinists and see what they think. Or maybe something like that
exists. It might take a few days to get you an answer, but I will get back
to you. Sounds interesting, at the least!
You're on the money with the 38 series. My 59' is a 1-Ton pickup.
Single wheels, full floating axles, 8 lugs and 4 Wheel Drive. She is one
stout old relic sporting the original 235, 4-Speed and 5.14 gears. I may
be
wrong, but I think that Apache was the designation for all the trucks,
including the LCF and school bus models. The series numbers run from the
3's to 10,000's, according to my manuals. In 58 Chevy dropped the 100's
numbers from the emblems, but the manuals still refer to them as 3100,
3800,
etc. The emblems are 31, 36, 38, etc. Well, I've got to run, but I'll get
back to you. V-e-r-y interesting... (I'll probably dream about how to do
this Smile!!!)
I've also forwarded your question out to the NAPCO Owners Group. Maybe
one of our members will have some good insight for you.
Yours, Kevin
