M602, modified M35

[rdixiemiller]

I bought a manual for an "M602, modified M35". TM9-2320-215-24P. I though it might be a manual for the Norwegian variant, I was wrong.
This manual is dated 1958. It looks like a normal gasser M35. It wasn't until I looked through the manual that I found what the modifications to the standard M35 were.
1) The truck has no air compressor.
2) Vacuum brake booster and wiper motors.
3) Military dash, but the air pressure gauge hole has a round blank-off over it.
4) Civilian turn and stop lights with no black out provisions.
5) Civvy light switch.
6) 12 volt system.
7) Civvy style (non sealed) starter, generator, and regulator.
Civvy fuel pump, mounted on the engine. No in-tank pump.
9) Single 6TN battery, mounted in the military battery box.
10) No flange on the tailpipe for the fording pipe extension.
11) Civvy style wiring connectors everywhere.
12) Civvy ignition, distributor, plug wires, plugs, coil, etc.

It looks like a deuce with all the special (expensive) mil-spec stuff removed. I would almost say it looked like it was designed for the civilian market, but it has a military TM. The brake booster and wiper motors look like the parts that were installed on period civilian vehicles. The pics in the manual look identical to a deuce of the period, the civvy turn signals are the only give away that it was not an M35.
David Doyle? Kenny? Westfolk? Maccus? any of you that have been deucing for years ever see one of these?

Air Farce?

I've not seen the truck but I have the manual.

As I understand it some manufacturer surplus (unshipped to the military) M37's were civilianized and offered to the public. The same could have happened to some M35's as well.

Towerguy1 is right that trucks were sold to civilians, but your 602 was made for export to friendly nations." Project Patriot- Hands Across the Sea." was the slogan this program was used. Other varients of the M44 series truck were supplied also.

I had heard of the Norwegian M602, but it had lockers on all 3 diffs and a ROPS system, and singles. I was not aware that there was a "generic" M602 that was "civilianized". From the looks of it, REO substituted standard civvy vacuum accessories for the military air setup, used the standard 12V civvy starting, charging, lighting and wiring system. Regular pickup style turns and tails were also installed. I would guess they put these parts on as the vehicle was coming down the assembly line, I can't see them having stripped the trucks down and converted them, too much cost. I was surprised to find a US Army tm on them, this one came from a Guard unit in California according to the stamps on the cover.

I think I remember seeing pics of a Deuce that was like that with Civil Defense colors and markings somewhere on the net.

The Norwegian trucks with the lockers weren't M602, they were classified the M621. The locker-equipped truck was powered by a naturally aspirated Multifuel, whereas the M602 was a gasser. Knucklehead has this one pinned precisely.

Best wishes,

OK. I thought the M602 was the Norwegian one. Still an interesting manual for a rare truck. I'm still surprised that there was a US military TM for this vehicle.

Well this is an oldie but in stead of starting a new thread I'll add too this one. The G-835 2 1/2 ton 6X6 trucks seem to have come in all the same typs as the M44's. If they were just for export why is there a US TM for them. And why did we make other stuff to go with these and include them in our TM's????

I was looking thought TM9-2330-267-14 dated June 1971 for the M149 water tank trailer it is also for the M625 water tank trailer the only thing diferent between the two is the lights and brakes. the M625 use 12volt lights and vacum brakes. The M105 trailers also came this way as the M105A2c.

If these were just for export why are the trucks and trailer in the U.S.manuals. It can't be for easy of printing , you would think they would need to be in a diferent langage.

Just one more thing to make you wonder whats what

A little off topic....

I used to have a G-749, GMC hydro....that was the same as an M211. Almost everything was the same. Though it had a fair amount of civi stuff on it that you could tell was there from the factory, and not "added" by someone later on. Plus rather that the everyday 4 digit VIN as all the others I've owned had, it had a crazy combination of numbers and letters more like everyday VINs. If I remember right it was a 1957.

Old thread but wish to add for future searches on the subject: I have a USAF Utica-Bend originally built as a M35, and apparently they made it into their own version of the M602 at some point. The exception on this one is they retained the blackout lighting system, original dash and gauges, and air compressor. The engine is a military version with its mil carb and other mil features, but has civvy 12V starter, gen, distributor. It came that way from the DRMO decades ago.

Good morning everybody.
The topic is very old, but I'm going to participate, even to register for later research.
I have a Reo M602, several came to Brazil in the 60s. It seems to me to be a very basic version of the M35a1, the engine was gasoline and ran on a 12v battery. The mirrors were the same as the Jeep M38 as were the brake lights. They did not have cabin heaters and windshield wipers were vacuum operated. The one I have I bought from the Brazilian army and had already been updated with the engine swapped for a MWM diesel engine. The rest remains the same. I never found the technical manual for the M602 to buy, it seems to me to be rarer than the M602 itself.

Greetings from Brazil.

Welcome to the site, and thanks for sharing your truck's story with us! That's pretty neat that the army did an engine swap.

Did the truck keep the vacuum equipment too? I'm guessing the diesel motor came with a vacuum pump.

Wow. That is a good looking truck!
Welcome to the Outfit!

goodnight

There is nothing left in a vacuum.
An air compressor was installed, the same one that equips the Scania 111. As a result, the windshield wipers were modified, becoming electric. The brakes are now air and liquid, with two master cylinders, one for the rear axles and the other just for the front, which I thought was very good because if one of them fails, there are still brakes to stop. The Brazilian army did a great job repowering the Reos. However, with the renewal of the fleet they went up for auction and I purchased one. There are few people like me here who buy it to keep it restored, most buy it to work on the farm, as it is a truck that can handle a lot of work.

I'm curious about the dual-circuit brake system. For the M35 trucks, a kit was made available to convert trucks from single-circuit to dual-circuit. Other trucks, like some M35A2 trucks built in the late 1980s and the M35A3 built in the 1990s came with dual-circuit brakes from the factory. Does your truck have the M35 air packs (air-hydraulic brake boosters), or a version of the upgrade developed in Brazil?

Good morning

I've seen a case where a reo M35 that had a single braking system ended up failing and the driver found himself in trouble. With this dual system. If one of the cylinders fails, the driver is not completely without brakes.
My Reo doesn't stay with me here in the city because I don't have space for it. In February I will be on vacation and I will go to my parents' house where he is. Once I get there, I'll send you some photos of the engine and brake system for you to see.

This photo was of a friend who was Reo's driver when they were still active in the Brazilian Army. The M602s were towing artillery pieces in the city of Bagé in the south of the country.
