Transmission PTO

KEITHS 1950 F68 · #1 (**permalink**) 02-23-2003, 10:50 AM

My 1950 F-68 (Canadian F-3) has a 4 speed spur (non-syncro) transmission with a PTO attachment bolted on the right (passenger) side. Will this PTO bolt onto other trannys for the 239 flathead? I'm looking to switch trannys, but wouldn't mind keeping the PTO!
Thanks.........Keith.

the four speed crashbox trans has strait cut gears. the t-98
[ 4 speed synchro-silent ] has gears cut on a helix. it won't fit unless you can find the correct gear to mesh. tim

Tim; Does the T-98 have a PTO option? Keith.

It has the PTO option. Most PTO's are made, then you pick out what transmission gear adaptor to fit it. Some where on the Dana.com page there is a way to "build" a PTO. I would highly recommend junkyard for it, because PTO's are very expensive.

yes there is a pto for the t-98. i think it is the same unit with a different gear installed tim

How do I recognize a T-98? Are there any external castings or plates or markings to look for?

Have you thought about an electric hoist? On my 51 Mercury M-3 it has a 3 - 4 ton electric hoist. It's just a electric pump on a hydrolic system.

Nathan;
Thanks for the suggestion......but I usually do things the hard way. I'm thinking about a hydraulic pump on the pto, running remotes and a remote hydraulic motor for air compressor, etc. As I say, I usually take the path of most resistance. Keith.

A PTO hydraulic really isn't that bad to put in. Just really expensive. There are also belt driven hydraulic pumps, you can run off the crank. You have to decide what you really want to do, and then figure out flow rates and pressures to get the size pump you want. If you want to run a hydraulic motor, electric is not the way to go because of the continuous running, and amount of fluid you need to pump.

T98 transmission usually have a T98 cast in them somewhere, on the side, and on shift cover.

In the electric system it only runs when you push the button. On my truck they had a button in the cab and on the back for ease of use.

An electric is fine for a dump, or a plow, but he said he wants to run a hydraulic motor to possibly run an air compressor or other devices. A dump runs for 30 seconds, to run an air compressor it would run much longer, and suck your battery dry. You also can't generate anywhere near the PSI/Volume electrically than you can with use a PTO. Electrically you could have a couple horsepower, mechanically you'll almost have the full hundred.

On our 69 F-750 there is an air compresser. It is as good as our old 3/4 horsepower air compresser. It maxes out at 100 psi. Our new 6 hp air compresser totally would waste it. It has more pressure and fills up 3 times as fast. The truck has air brakes so the compressor is ran be a belt. I don't think that think could even fill up one of the tires.

If you took your 6 hp compressor and hooked it up to your truck engine, you think it would work the same? Of course it would, because the truck engine has MORE than 6hp, so it would run the compressor.

The air brake compressor isn't made for filling tires, so it only puts out so much, AND you don't want the thing robbing tons of HP from your engine(sorta like switching on the A/C in car) so they limit the size and output of the compressor. The air brake compressor will fill a tire no sweat, I use it all the time on my semi.

Your home compressor is running on 110AC, a lot more power available than 12DC.

What I'm saying is that if he wants to run big stuff, he's better off with a PTO/Belt driven pump.

Hi guys;
I've been in the woods, away from computers, for the week. Thanks for all the discussion and ideas, while I was gone. Some of the planned uses for the hydraulic pump include running a woodsplitter, and a front mounted V-snow plow; along with the air compressor. I plan to keep the 6 volt electrics (heck, it starts even at below zero temps). Regards. Keith.
