Aircraft tug question??

I know this probably isn't the correct spot to post this question......but I'm looking for any information on a Coleman aircraft tug/industrial tractor. I believe it was built for the air force. Its a model numer A/S 32U-18. any help would be appreciated.
Thanks

If it is the MB4 type I have some manuals and parts books some where. The MB4 has 4 wheel drive and 4 wheel steering and came with at least 4 different engines through the years.

This unit has a v-8. I was told it's a Chrysler 440. That might make it a mid 60s unit. It has a #60,000 Tulsa hyd winch behind the cab. Looks like a factory install. I figure it could push a 12' snow blade at an airport. The price is right!Any info would be appreciated.

My MB4 did not have a winch and none I have looked at had winches. If you had a picture I could tell you if it is a different type. Mine had dome type covers on the front wheel hubs. I agree they would make a neat snowplow.
Greg

Is this the one you are talking about?

Yes, that is the MB4 type.

I haven't aquired this yet. It's got a bit of snow blocking it in and its -29f right now. I'll get some pics up soon. It has 14x20 tires and the wheels look to be standard the standard 10 hole type.

There is one on Craig's List-Boise right now, that appears to be a civi model of the one shown.

I don't think a 440 would fit in one of those without serious modification. The hood looks awfully narrow. I have seen a few of those for sale and all seem to have an inline 6 cyl.

The same one that was on Craig's List-Boise is now on EbayMotors under military vehicles. The description says it has a 6-cylinder.

The MB4 that I used back in the mid-late 80's was a Chevy truck cab and powered with a 6.2L diesel. It had reduction gears at each hub, 4wheel steering and were permanently in 4wd low range. I towed any thing from twin seat trainers to C-130's with the MB4. They had a top speed of maybe 25mph with the frames mounted directly a 3"chunk of rubber on the axels, that was it for suspension. The seat belts were used to keep your head from smacking the top of the cab when you hit a bump.

Here is the machine! Chevy pickup is shown for size reference. Tires are 14:00x 20, winch is a Tulsa #60,000, I've been tol the engine it a 440 Chrysler.

The one I owned had the same cab and general appearance but lighter running gear and no winch. Now I wish I had it back as a snowplow. What I do remember is thinking coleman is out of business but fortunately the tugs are built like a kitcar,a lot of common components. Good luck with it.

Greg

Well, did you get it bought?? It sure looks handy for alot of things! Are you going to use it as a snow plow??

That's definitely a big block Chrysler in there. It could very well be a 440.

I commited to buying it. I hav'nt got it started yet. It will be used as a snow plow at an airport or just push anything thats in my way! It was built it 64 so I think the engine is a 440 industrial.

The 440 didn't exist in 1964 so unless it was replaced, it's probably a 361, 413 or 426. Naturally anything could have been put in there over the years. To ID the engine, look on top of the engine right behind the water pump tot he driver's side. If there is a pad there like in the pic below, it is a tall deck RB series engine (413, 426, 440). Note the location of the last bolt to the driver's side on the valley pan clamp bar in the pic to help locate the pad. If there is no pad in this location it is a low deck B series engine (350,361,383,400) and you can find the ID pad near the distributor. The pad is at an angle behind the distributor, machined at the same angle as the head mounting surface. Either way it is a big block and the CID will be stamped on that pad as in the pic. I wouldn't hold your breath on seeing the "HP" like in the pic as that denoted a High Performance engine, lol.

Thanks for the info. I'll check it out.

This was a tug to pull 737's ect.
low geared. I beleive it goes along pretty good. 35- 45 mph.
it is 7' 6'' wide x 13' 6'' long.
Parts are still available for these because the parts are the same as other vehicles or trucks. They used the axles brakes ect on a lot of different trucks, not just american-colemans.

The powertrain combination is as rugged as they come. The Perkins Turbo Diesel engine ignites right away, it has an even idle, and it delivers serious torque to easily power the truck. The gears engage properly, they shift easily, and they pull impressively. The differentials, with planetary gears, are serious torque monsters! They pull with unquestionable strength!

The body on this truck is also in exceptional condition. The bodylines are straight, the paint is healthy and shiny all around, the windshield has no cracks, chips, or bull’s eyes, and the seats have no tears. Everything is functioning on this truck! The powertrain performs strong, all the lights (markers, signals, headlights, indicators, warning lamps, flood, hazard, beacon, etc.) are fully operational, the brakes are strong, and the 4W steering switches modes easily. All the gauges function, the heater works fine, and the floodlight swivels and illuminates properly.

Noteworthy features on this truck include:
Perkins Turbo Diesel Engine
3 Speed Powershift Transmission
Heated Cab
Tear Free Seats
2 or 4 Wheel Drive Modes
4 Wheel Steering
2 Wheel Steering
Coordinated Steering
Crab Steering
Planetary Gear Differentials
Hydro-Boost Braking System
10-Ply Tires
360° Floodlight
Flashing Beacon
