Finally pulled her out of the weeds

Good Morning and Happy Thanksgiving to everyone!

I posted pictures of this truck with questions over a year ago, if any of you remember. But, I have a little more knowledge about her now.

She used to be a water truck to deliver water to the firetrucks on our local mountain range. She has less than 11,000 miles on her originally so Other than changing fluids and getting rid of old gas, in theory, she should start up, run and drive. I have put a battery to her and poured a little gas down the carb and she did pop off for a few seconds. So, a worthy project to get running I think.

She has the 392 V-8 with a Holley governed carb. I contacted Holley directly and they were absolutely no help for a rebuild kit for the carb BUT they did give me a number to call and even told me this company has more older Holley carb info & parts than Holley does. If anyone needs parts for these older Holleys, the place is "The Carburetor Doctor" out of Lake Jackson, Texas. They had the kit and I now have it here on my shelf. They were awesome to work with.

The transmission is the Allison MT40, 6 speed automatic transmission. So, in the cab, there are 3 pedals in front of the drivers seat. The gas, the brake and a long skinny one where a clutch pedal would normally be. Crawled underneath and the pedal goes to a linkage which crosses under the transmission and is tied into a valve body on the side of the transmission with 2 hydraulic lines coming out of it. Haven't traced the lines yet but does anyone have any guesses? I do know these transmissions have 2 places where PTO's can be utilized but would this be a hydraulic PTO from the transmission? I haven't found it in the service manuals yet or any info what it would do.

3 levers on the floor. 2 of them go to the transfer case. My guess is high/low, Parking brake (this is a for sure) and a PTO out of the TC. But I haven't paid much attention to the transfer case yet. My guess is they had a PTO for the water pump and has been removed for a while now.

And yes, the truck is a Coleman axle truck! The front axle is wider than the rear for better off road capability and there is a warning on the dash that says max speed is 40 mph. lol

The tires are shot and this will be the biggest expense of them all! They are 15 x 22.5 tires & rims. Yup, heavy equipment tires. Cheapest I'v found is $1000 per tire plus shipping. The ones I am eye-balling are $1650 a tire but 20% off if I buy all 4 at once. Huge discount but still hurt the pocketbook.

Decided to see what this little video would do on Tictok. haha

Looking thru the Allison service manual and I found my answer on the 3rd pedal on the floor!

Here is what the book says:

"The hydraulic retarder is operated by depressing a foot treadle. The speed of the vehicle can be effectively reduced on straight road, curves and downgrades without the use of the service brakes."

It's a hydraulic transmission brake.

Certainly was set up for heavy loads on grades 

Did get anything on the Tick Tok link got any photos?

We loved photos 

I have a 1750 4x4 with DT466 and a six speed

Heavy loads.... You are correct! The tank in the bed is probably 1000 - 1500 gallons made to haul water up and down the mountain for wildfire firetrucks. Between the super low gearing of 1-2 gears and the low range in the transfer case, and the hydraulic retarder on the transmission, heavy loads should be no problem for this thing. lol

I will take some current photos tomorrow and get them posted. 

I will be sharing the progress regarding resurrecting this old girl. I'm stoked! Love these old trucks!

I have BIG plans for her and if all goes well, she will be back in commercial use by spring, even if new paint isn't on yet

No chase vehicle. I'm not going to use the original tank either though. 
Another thing I do is salvage old houseboats and this old girl will be fitted with a 50 gallon tank from a houseboat, located in the bed that will be accessed the drivers side bed door.

I figure 50 gallons should get me about 50 miles or so in this old girl. lol

If needed, I can add a second 50 gallon tank and have it as a transfer for both this truck and to fuel customers vehicles if needed.
