Hey everyone im new here and looking to buy a m1009 cucv in the next few months. I do know a little bit about the m1009 cucv from research but i need more info about it.

What i know about from research
They have 10 bolt solid (dana 44? or 8.8) front and rear, eaton locker in the rear, 3.08 in the rear the front is open. The electrical is a 12/24 volt system, dual batteries running a 24? volt system for the engine and a 12 volt system in the rest of the vehicle. The motor is a 6.2l Diesel, (which ive heard are kinda slow could use a turbo)

I am just mainly going to use it for moderate offroading/ camping/ and very slight daily driving. I plan on putting a lift on it so it can clear 33s

I just really need to know what to look for/ what to know when i go look at the blazer.

Thankxs for the help.

 

I'll be honest, I don't know a whole lot about the military style blazer, but I do know a forum that will answer all your questions.

Check this site out...
Technical Manual for M1009

I copied this information from another forum, but it may help you...

"Parts are very easy to get from ebay, NAPA, and so on. So dont be afraid of the parts issue, i have yet to run into not being able to get a part for my m1009.

Problem areas are rust first off. Wheelwells, rockers, and rear tailgate are some of the worst places. The trucks are originaly 24v, but some people have tried with varying degrees of success to convert to 12v. I would be wary of a conversion, you just dont know what you will get into.

Other areas are IP pump, glow plugs, starter relays, fuel lines, but most are pretty easy fixes. You can download all the PM's and Tech manual over at steel soldiers. There can be some random electrical problems related to bad relays, corroded connections, and so on. But so far I have not had any and the only issue I had was putting a new starter in changing all the fluids, replacing water pump, and replacing a cracked cross over pipe.

I assume it is a blazer m1009? For 3k with rust seems a little high. I paid just over that for a titled one with no rust and was in great shape.

The 6.2 is not a barn burner, but it does get about 18 to 20 mpg so its not all bad."

 

The 6.2 Detroit has a real bad tendency to develop cracks in the heads, and everything on the M1008/M1009 is going to be solid state. The starting system is 24v, so you won't be jump starting it with your daily driver. They have an NP205 transfer case, which is gear driven, but the reduction ratio kinda sucks. They only have heat - no AC, and the miles tend to be low, but idle hours tend to be high, meaning you can expect a lot of carbon at the end of the cylinders and a lot of sludge at the bottom of the crankcase.

 

If the idle hours are high and i expect there to be carbon built up on the cylinders would i just be able to run some seafoam through the crankcase?

 

I don't know how well it would take off the carbon... we always have to scrape it off whenever we do a rebuild in order to get the pistons out of the block. The oil treatment would be good for getting the sludge out of the bottom of the crankcase, and the fuel treatment wouldn't be a bad idea.... the military uses kerosene-based JP8, rather than diesel fuel... if it leaves behind any residue or not, I really don't know.

 

pssshh, I wouldn't have asked questions... I would have just went and bought it lol.

 

at the time they were using these it wasnt jp8 they were probably either using ts1 or jp4 for their planes so thats most likly what they were running in the blazers, ts1 is cheap crappy gas and will turn to water pretty quick jp4 isnt to bad but itll leave behind some residue.
