Mike, thanks for the reply.

The pto is blocked by the transmission thingy.

About the  chimney mounts, they're hydraulic. Ans will be transformed into log turners on the sawmill. Cylinders will go on the blade. Someway. And i just found some parts from a snowplough, with cylinders which will become stabilisers like on my crane. And the guy has a winch for little dough i think. A pan brand. About 15/20 tons.

I guess id hafta see this gear reduction.  I meant a power takeoff acess cover on  the side of the trans.. Not a pto shaft at the bumper.

Take lots of pics as you go!

Mike, this is pure weirdness.

It's dual transfer case. But not normal way. As in a crawler box. One feeding the other.

Nope. There's belts on the shaft from the gearbox, this shaft goes to the transfer case. The output of this transfer case is linked to the output front shaft of other transfer case. I dont even understand how this can work.  Since there's a differential in the normal transfer case. I think i would have to lock the diff, for the four wheels to work. I'll post photos in a minute.

Backside of the second transfer case, with the pulley cover.



Front, with the pulley visible, and the shaft, which is linked to the front output of the transfer case.

 

Still, that doesn't tell me where to take power for the winch, and hydraulics! I'm onto a lead for the stabilizers apron thingy i want at the back. And for a winch too.

I have taken out and cut the blower's slides.



Big one has a smaller engine (4236 4 banger turbo) than the little brother!  :(



And the big V8, i wish i could stuff this one in the  crane! 15 liters!

Guys, one question for you. It would be complicated for me to fit the hydraulic pump on the end of the crankshaft, without raising the radiator.

Hard also, to use the space for the PTO, the gearbox shaft isn't standard. I have hard time finding parts.

I have studs on the crankshaft pulley. And i have a three groove one that i could fit there. and a matching 2 groove for the pump.

Do you think i could power the winch with two 1/2" belts on the pump?

Thanks.

Max.

Run the machine and see if its an engine speed pto or a ground speed.  Also if it is always live or if it has a neutral, if it reverses etc.  Would be good if you could determine an rpm with an IR tachometer.  Googling for a manual or parts breakdown of the tcase might help.  If theyre defunct you can always try calling whoever bought them out for old literature in archive, ive successfully done so with funk transfer cases.  Takes some time.


What family are the belts, A, B, C etc?  How many gpm do you want, and at what pressure and rpm?

American medium duty plow trucks with automatic trans often use a belt driven pto clutched pump just fine.  Im inclined to say no problem.  It is said that the fixed fan on a dt466 can consume something outrageous, like 60hp, at max rpm.  I dunno.  but its a pair of A belts on mine.

The PTO on the transfer case is on the end of the gearbox shaft.

So gear dependent, with a neutral. Tcase has a neutral too. So i could winch without having the wheels engaged.

But i'm wondering if i don't go shaft there. I have a lathe, a milling machine. and i can tackle the male part for this. And the housing.

And have a little pump for the two or three rams i need.

V belts were A type. No good!

Mike thanks a lot for bearing with me.

What kind of cable speed should i be looking at for the winch?

Any chance of finding a cheap hydraulic power pack? Run the winch with a separate engine/ hydraulic pump/ oil tank mounted on the back.
I imagine if you break a housing/ case on the old transfer unit it might be time consuming to find a replacement.

Glad to help. 

Wallensteins max around 250 fpm on a 540 PTO.  Allied W400 skidder winch does 367 fpm.

Just keep in mind the faster the line speed the more input torque required to pull same log.  High input torque places more load on that rare tcase as riwaka mentioned.

12 gpm out of your A belts at 3000psi using "central hydraulic" pump setup might be the fastest route. 

https://www.surpluscenter.com/Hydraulics/Hydraulic-Pumps/Clutch-Pumps-Hydraulic/1-45-cu-in-Hydraulic-Clutch-Pump-w-Dual-Groove-V-Belt-Pulley-9-1737.axd


American 5ton military trucks had 20k worm gear winches on them with hydraulic or pto power and freespool, usually garwood.  I believe the pumps made 14gpm at 1000rpm or about 25gpm at governed speed. 

  Tulsa and braden are two other common brands and are also typically on knuckle booms and crane/hoist trucks.  Ive always hoped to find a dual drum wrecker winch with the swivel blocks for my skidder project, like how the euro machines are set up.

Thanks a lot guys.

Well, gearbox and tcase are not that rare. Used on lots of army trucks. It's the pto which are rare. Even more the bottom one, than the gearbox top shaft one.

Mike, i don't quite get what the dual winches are for ?

Smidgeo pron!



Pulls like a charm, needs a winch tho. Turns on a dīme, with it's four wheel steer. I need to fix the actuator of the rear locker. Change the fuel and filters. It stinks. An oil change would be good too.

Glad you got her going. 8)
But if someone drags a log like that on a gravel road he should be the one who cuts or saws it.  ;D ;D
Make sure you know how to fall properly when you fall and as to not hurt anyone around you.
Also remember, it's not the fall what hurts, its the sudden stop. !!

Well, anyway, it'll go on my saw. But i might debark and run the pressure washer to it.

No choice, i have no winch nor a  up and down log basket with rollers. Yet!  :( The bridge above this road is about to fail. So i couldn't go with my crane. And i had to drag it on the tiny path in the woods. So, i might as well carry on. This is not my tree. One of a friend. But i dragged the three firewood ones the same.

Mind you the video is crappy.

Also, i have 5 nice saw trees, under the chairlift i work on in the winter. That i'll need to pull before the winter. And if i don't have the winch, it will end up the same as this one.  :( :( :(

And it doesn't appear that i will be able to buy the winch any time soon.

Well, broken the adapter piece of the crane's jib. :(

With this one.
 I'll put pics later. I can't do it from the phone.
