Replacing the M880/M890 series, the CUCV represented General Motors' first major light-truck military vehicle production since World War II.[11] GM CUCVs were assembled mostly from existing heavy duty light commercial truck parts. The CUCVs came in four basic body styles: pickup, utility, ambulance body and chassis cab.[11][12] The M1008 was the basic cargo truck, the M1010 was the ambulance, and the M1009 was a Chevrolet K5 Blazer uprated to 3⁄4-ton capacity.[11][12] With the exception of the M1009, the trucks were all rated as 11⁄4 ton (commonly called a "five-quarter"), even though some of them had payloads in excess of that. There were heavier-duty variants, including the M1028, M1028A1, M1028A2 and M1028A3 shelter carriers (the shelter being a mobile command, communications or intelligence operations enclosure).[11][12] The M1031 was the chassis cab. These latter trucks were all rated for heavier 3,600 lb (1,600 kg) or 3,900 lb (1,800 kg) loads, compared to the M1008s 2,900 lb (1,300 kg) load capacity. The M1028A2 (converted M1031 or m1028a1) and m1028A3 (converted M1028) models had dual rear wheels.[12] Many M1028s were upgraded at the company level to M1028A2 and A3 specs-the dual wheel rear end arrangement was a result of the M1028 flipping on its side because of the high center of gravity when carrying equipment shelters.[13]
GM produced some 70,000 CUCVs from 1983 to 1986 (model years were 1984-1987), though most were model year 1984.[11] Chevrolet continued to build CUCVs in low numbers from 1986 to 1996, mainly to accommodate military markets that needed replacements for existing CUCVs.
Powertrain
Edit
All CUCV Is were powered by GM's 6.2L J-series Detroit Diesel V8 engine non-emissions diesel.[11] These were rated at 155 hp (116 kW) and 240 lb⋅ft (325 N⋅m), which was 5 hp (3.7 kW) more than the emissions diesel engine of the time. They were all equipped with the TH-400 automatic. All but the M1028A1 and M1031 used the NP-208 chain drive transfer case. The M1028A1 and M1031 units had a slip-yoke rear output version of the NP-205, which was specified mainly for its PTO capacity. The CUCV series had a governed top speed of 55 mph (89 km/h).[14]
Axles
Edit
The M1009 Blazer used 10-bolt axles (front and rear) featuring 3.08:1 gears. The rear axle was equipped with an Eaton Automatic Differential Lock (ADL) while the front was a standard open differential. The M1008 trucks used open Dana 60 front axles, with the M1028 and M1031 variations often having a Trac-Lok limited slip. In the rear, the M1008s used the GM 10.5-inch (270 mm) 10.5" Corporate 14 Bolt Differential with No-Spin lockers (the commercial trade name for the Detroit Locker). Rear axles on M1028A2 and A3 duallies are Dana 70 HD. The axle gear ratios were 4.56:1.[15]
Electrical
As with other military vehicles, the CUCVs used a 24-volt electrical system.
It was actually a hybrid 12/24-volt system that used 24-volts under the hood for the starter, volt meter, diesel engine glow plug circuit along with the mandatory NATO slave receptacle for jump starting any 24 volt NATO vehicle, and hookups for military radios. The rest of the truck was 12-volt.
It was equipped with two 12 volt batteries and two 12 volt 100 amp alternators. One alternator is isolated from ground and connected in series with the other. These produce 24 volts with a 12 volt center tap much like the 240/120 volt domestic house distribution system. The 12 volts to ground were derived from the center tap.[16][17]

I was on the Material Fielding Team for the Army's CUCV in 1984-1986. I still have all the Chevrolet TDP's as well as the Manuals for the "D" Trucks. It tickles me that all the people on KZbin profess to be CUCV experts and were not even born when the vehicle came about..

[@johnrobinson7021]

people younger than you can be smart as well.

I'm installing the Dog Head Starter Relay on my Truck now. I've an '86 M1009 I purchased 10 years ago, its been sitting in my garage since 2013 when the original starter relay stuck, it melted my starter! Count me as a new subscriber.

[@spenceradamsjr]

Thanks for the vid. I agree; Keeping the electrical system original is best. My M1010 that I am working on right now was butchered when I got it. I have spent a lot of time repairing electrical issues and plan to reharness the whole vehicle soon. Also working on the fueling system. Mine is getting air in the return line. Chasing that now.

[@EmilioTorres-z3c]

Thank you for your honesty. Keep up the good work brother

[@wild1athletics]

love my k2500 6.5td with the 14 bolt rear end. Would love one of these as a project some day

[@cucvvermont6477]

You already have a nice truck! But grab a CUCV sooner rather than later, the value is only gonna go up. I insure my CUCVs with Hagerty and they are acknowledging the increase in value like never before.

[@marvz71]

The only circuits that are 24V are the starter and that useless NATO plug. A 12V conversion is the most common sense thing to do right out of the box for its compatibility with the standard models of these trucks.

Most people that don’t like Detroits don’t know them.

Recently bought an M1009 and saw your video. Great information and glad I came across your video before daily driving it. I went ahead and picked up some glow plugs from Kennedy Diesel and when I received them they have Wellman engrave on them. I went ahead and took another view at your video to make sure I hadn’t misheard something. I’m not sure if I ordered them from the wrong Kennedy or what happened but thought I’d pass on the information.

[@cherokeeronnie]

Did you get the quick heat??? Mine don’t say well man

[@kriztofer9968]

I did and I even called him and he was a bit annoyed at the fact that I questioned the brand/ product that was sent to me.

Nato 24V system will NOT charge battery if a Gen 1 or Gen 2 bulb in the dash burns out bc whole system including bulbs is wired in series!. Swap the bulbs in the dash when you get one or at least be aware why your battery isnt staying charged bc your alternators WILL NOT charge if one of the 2 bulbs are burnt! Steel Soldiers is your freind. Money is your freind aloong w patience. Be prepared to get $uper $pendy. These things are 40 years old. Have a network of people or mechanic(s) that arent scared of the crust and 6.2 IDI world. Got my zero rust CA Desert based 29 palms Marine 1008 5 years ago - she was wasting away (high altitude no humidity) on a sheep farm in NM. Got it back to Socal where it is smog exempt. Motor is a reman unknown hours but is almost leak free. The rancher dude who owned it did 12V conversion w civi cluster, manual glows already all lined out. I swapped to AGM Optima battery, spin on filter, '92+ Inline lift pump in frame and now starting is NOT a problem. Shes got a Banks Sidewinder from a donor truck I yanked out as of last month, Inj Pump is timed to proper advance now and is waaaay smoother and quieter at Idle. I just Resealed the front end of motor w Fresh Harmonic, seals, PS belt, New hydroboost lines(old ones leaking at 40 years) last year I did 700R4 w custom higher stall, advance adapters to the 208 TC and my trans shop (Art Carr down the street) did a CUSTOM kickdown bracket kit from Lokar instead of using the very hard to find factory brackets. its on ORD 4" lift w 1.5" forward 1" lift spring shims(~5" lift). PSC 2wd Box BRacked frame welded in, X-over steer, No sway bars on 38" Patagonias. She rolls down freeway 70-75 all day now. Hillbilly Wizard had some extra gun rack locks I put in that the last owner removed. These things are rewarding if you got the time/space/money/resources. Restored gauge cluster w $50 clear cover, $20 LED bulbs, Nice steering wheel $180, $70 Carrhart dash cover over the cracked pad, looks really decent inside. Its now a daily for my son in H.S. now. Its got onboard air w Vair/ARB parts for barge horns and tire inflation. LMC has taiwan vent windows $180 each easy to swap compared to trying to rebuild crusty o.g.'s. Im 5 years in - next up is seat/visors from USA1 and next year shes gettin ADS Coil over setup and CARC Respray/straightening. Save em!

[@wes11bravo]

Hey brother - I plan on getting one someday and was wondering if you had any knowledge of putting AC in one. Either all civvy GM or Vintage Air - any recommendations?

[@fmagalhaes1521]

@CherokeeRonnie. Are the injector pumps on the M1008 and M1009 mechanical or electronic? Please let me know. Many thanks!!! :):)

[@jayarmstrong3848]

Put a 1 wire single alternator in it, wire batteries in 6:13 parallel, put a 12 volt starter in it. F that 24 volt

[@doughboy1966]

Would love to own one but the luxury of AC is very expensive. I wonder if anyone has retrofitted another AC/Heater out of like an import car because of the small footprint of them.

[@cherokeeronnie]

Guy on KZbin put ac on it slams kept both alternators to

[@mandovapehater6988]

I recommend get ready to run to napa for a basic fuel filter assembly. The original is hard to find parts for if not impossible. I replaced mine with napa stuff when the bleed screw wouldn't stop leaking and no problems. At least not yet. Removed the original and bolted the new back in its place. Also, how do you tell about the harmonic balancer being good or bad?

[@adventurehawksancientharmony]

I restored a M1008. Money pit

[@ronbonick4265]

great info Subscribed

[@BPzeropoint]

what would be your advised top speed to if going 2000 miles on the interstate? and what would be the Tell Tale Sign of a bad harmonic balancer and or cracked crankshaft? I thought the cranks were forged steel?

[@user-jv5bl9sl3b]

I have 3 of these trucks on my property. Just got the key for them and am going to start them for the first time in 10 + years. Any advice?

[@RyanSteele92]

Sale me one

[@coreygood86]

Make sure your batteries are in top condition and good glow plugs.

[@mandovapehater6988]

One key should start all of them I believe. Unless someone changed them out like I did.

[@kriztofer9968]

Do you have the part number for this solenoid to make the mod for the starter? TIA!

[@RDCM1008]

link for alternators?

[@cbcinfla]

y'all know you're making a video, right? You know, where you show the truck and the parts you're talking about? See, just staring at your beard for 6 minutes ain't exactly interesting.

[@scumdog88]

Put a Sbc in my when I got it. Those 6.2 suck and so does the wiring.
