Air Conditioning a Deuce

[Odyssey M]

D,

I like your gas cap lock idea. I have been looking for a way to lock down my tank.

 

[zout]

Just been watching the great install work.

I am sure you already know but for those viewing and considering an install - be sure to keep your pressure gauges on the system at idle as I would be concerned with air flow as mentioned above and being able to control pressures in the system with no induced air flow across the condensor.

You may wind up installing a thermostatic controlled fan system above the condensor.

just my .02 cents worth to make sure your getting your full money worth of all that hard labor.

Woodsplinter & Zout,

Thanks for the heads up on the air flow. I have already ordered a 24v reversible cooling fan to mount on top of the condenser. I will use the gauges to determine if pushing air down through or pulling it up through would work the best. I will keep you posted. It has been raining most of the week and forecast to do the same this weekend, which has hampered finishing it up.

Air flow either way is fine and acceptable - what the dynamics of the effect are - is that it is to remove the heat from the freon that has grabbed it from the evaporator in the cab and thus return it back into the system minus the heat (thus you see it pouring water out the drain under the evaporator onto the ground.

Whether I stated this correctly it is what needs to happen - its in my head of where high and low pressures are in the system and which are either liquid or vapor as well.

Being where you are it is going to make the system operate correctly with thermostatic controlled fans under your high pressure at the correct pressure to pull the system into lower pressures.

Ever sit next to a semi truck in the summer when his ac is on and has an auto controlled engine fan - either high engine coolant temps kick the fan in or the ac system from the pressure switch's on your drier.

Dave,

Are you cold yet?

Another question. Do you think it is possible to mount all the internal unit, minus controls, in the toolbox under the driver, and duct this a/c in the cab. Just wondering about the size and volume of space available in the toolbox.

Also, can you include a picture of where you located your controls.

 

[DHennon]

I will have to look and see if there is room to install and access the evaporator using the tool box. My concern would be access and sealing the box to prevent dirt and water from getting in. Neat idea if it would work.

I sent you a PM.

 

[zout]

Just so you would not have to fit installing in a tighter space - I would ponder the concept of air sawing the remainder of the front of the tool box off for more room to fit properly and seal and also to run ducting. Then mig weld the plate back on and air sand the weld to conceal what you have done.

But I believe there is enough room there to properly do this and to seal it as mentioned from weather and to duct air into the cab.

If you did not want to do the above - just remove the tool box and do your thing with good measurements.

Those control cables are long and I think you would have plenty of available cable.

Just wondering if anybody has tried one of these types ?

 

[Lonesome715]

Is that an all inclusive unit? That is how I understood it.

 

[3dAngus]

It's all inclusive for the newer MVs in Iraq and Afghanistan.
The older vehicles we usually purchase may need a different and smaller coil, and modification to the compressor bracket..
These kits go right on down to the the tie wraps. Lots of parts.

 

[Lonesome715]

That is what I was thinking of when I saw it. I remember those units bolted tot he tops and back of cabs.

 

[dilligaf13]

That's pretty sharp. Anybody ever use these systems before?

 

[DHennon]

OK, I am back. I have spent the last several weeks recuperating from surgery and am ready to finish up the a/c on the deuce. I did not have to work outside in the heat, humidity, and rain the last several weeks, and I am glad I got all the heavy work done before the surgery.
This past week end I fabricated bracketing for the receiver drier, finished mounting the evaporator, and installed a 24 volt, 16” cooling fan above the condenser. If the 16” fan is not adequate, I will replace it with 2, 12” fans.
Today, I took the Deuce to the local Pirtek hose dealer and fabricated new, longer a/c hoses and installed them on the truck. I needed to have some of the straight ends changed to 90 degree ends, and needed some longer lines to hook up the condenser. It was straight forward work, and I am pleased with the results. It took about 5 hours of think, ponder, measure, cut, fabricate, test fit, adjust, and final assembly. Though it has been both challenging and enjoyable, it seems for every step forward I have taken on this journey, I have to take 2 back, and redesign something.
I will hook up the vacuum pump in the morning and make sure I don’t have any leaks. While the vacuum pump is doing its thing, I will finish wiring up the system, then charge with Freon, and see if I can get cold air!
Next I rebuild the winch……………………..

Great to have you back Dave. Now to see this project done. Good luck with I

Hope to see it at the Ga rally.

I have been reading your thread with great interest because I bought two Air Force G-30 box vans used to transport troops and materiel to the flight line. Both are powered by 6.2l diesels and neither has AC so I must do it all from scratch.

Needless to say, I'm very interested in your information. I have gone on other forums and all I get are smart aleck snarky answers from people who have never turned a wrench. I have turned a lot but never did AC, so I have to learn from someone who knows and will explain things a little, instead of saying " Oh it's easy." So is surgery to a seasoned surgeon, but I wouldn't have anyone else open me up!
Thanks for your willingness to share!!

Once I get some things done, I hope to share too.

 

[Woodsplinter]

Strelnik, send a PM to "welder sam" or check his build threads as he recently put in an a/c system that might work for you. Don't know exactly what you have but maybe an RV style roof mount might work. Just throwing out some ideas- hope that helps!
Please post some pics of your Kubelwagen & staff car- we would love to see them even if their not restored yet!

Nice work Dave. Keep up the good work!

 

[shannondeese]

I just installed the same heater/AC system you have. I was wondering how you came out with the wiring. I am at the wiring point and am stumped. Any help you can give I'd appreciate it.

Zout indicated there was a trick to it. He spenta lot of time working and researching the problems.

At one time he was online and said he had the drawings to do it correctly.

He offered to help anyone if they needed it but not sure if he still has the data or if the offer still stands.

Edit: oops. Didnt see your response where you PMed him Dave. Maybe you have the answer.
