So I have been looking for a decent square body for some time now. Didn't really have my eyes on anything in particular, but the frame and body needed to be in as good of shape as I could find.
Last week I came across this beast on marketplace up in Massachusetts. It's a 1986 Chevy M1031. Which is the military CUCV service truck.
It is I'm great shape. Frame is rock solid, and the cab has very, very little rust. It is also mechanically sound. A couple little leaks, but that's to be expected.
It has the 6.2 diesel, th400 trans, np205 t case, king pin Dana 60 front axle with a limited slip, 14 BFF rear with locker, and 4.56 gears. The service body is all aluminum. It used to have a PTO driven generator and air compressor, but those have since been removed. The PTO is still on the t case though.
My plans are to keep it fairly original, but add a few creature comforts to suit me better.
Welp, one PA winter is already taking its toll. The little spot of rust that was on the front fender got bigger and the bottom lip of the rockers has some starting.
The fender I knew needed to be fixed anyway, so I'm not worried about that. The rockers looks like just surface rust due to some paint that chipped off. It doesn't appear to be deeper than that since a little scuff with Scotch Brite and it was to clean metal.
Haven't driven the truck in a little while. Fired right up tonight. Putting it to work tomorrow towing my trailer through some potentially muddy terrain.
Not much weight, but I figure this truck is the best of the 3 to take for potential mud. It's the lightest and has the locker in the rear and posi up front, plus the tires obviously lol.
Just need to help my father get some lacrosse nets delivered from the township building to the fields for the teams he's coaching starting soon. The one field they are working on, which is where the mud may come into play. I'm going early in the morning to try and catch it while the ground is still frozen.
I've been itching to start working on this truck again. But the weather hasn't cooperated whenever I find time to work on it.
Well I thought I was done with the plow for the year. But mother nature had other plans. Got a quick storm today. Was 70⁰ last weekend and now this lol. Hopefully this'll be the last storm of the season. I'm ready to start working on the trucks again.
Well batteries didn't happen over the weekend. Weather went to shit.
But I was able to get the batteries swapped over tonight. Still need to clean up the cables and wiring, but the new batteries are in. Can tell a difference in cranking speed. The old ones weren't bad by any means. But when I got 2 brand new Deka 1000cca batteries, I figured I'd put them in and throw the old 2 on a tender.
Also sort of got my radio working. It's really just a temporary rig job for now until I can get time to wire it in properly and mount the speakers the right way. But at least I got tunes now and don't need to keep using my Bluetooth speaker lol.
I obtained a 55 gallon drum of diesel with some gas mixed in. Had a driver top off their tank with gas, so it needed to be drained. We need to pay to dispose of it, so I let it settle and then sucked the top 50 gallons out of the drum and pumped into a fresh drum then topped the rest off with diesel.
My plan is to mix that with filtered used engine oil. My initial plan is to try a 70/30 mix fuel and oil. May increase the oil mix if it works good. I have about 30 gallons of waste oil at home and a virtually unlimited supply at work.
I need to setup a filter system for the oil. My initial thought was doing small batches and then mixing it thoroughly before dumping it in the tank, then filtering it one last time before it goes in the tank.
I will be tracking fuel milage and fuel filter life, as well as how the engine runs and the power output.
My tank is full at the moment so it'll take a little bit before I get to test it.
Had a little free time tonight before dark and was able to get my front dash speakers mounted and I swapped my cluster lights to leds.
Was able to get the dash pad installed but need to get a few new screws. Since the dash pad was off for the last couple months I have misplaced a couple of the screws. I know I was missing a couple to start with, but I lost some more for sure lol.
So now I need to run my wire for the rear speakers, make mounts for the rear speakers, and then clean up wiring. Hopefully this weekend I'll be able to get it done.
I also found why my 4wd light doesn't work. The wiring from the switch on the transfer case rubbed on the frame and corroded the one wire. So I'll fix that wire and secure it better and that should fix my 4wd light.
I also plan to mix my first batch of fuel this weekend.
Got my rear speakers mounted in the rear corners. I thought I had some stainless sheet metal at home but I guess not. So I'll need to make actual mounts for them. I also got my sub installed behind the seat.
Everything sounds really good. Still need to clean up the wiring once I finalize the position of everything.
I'll also be mixing my fuel today. Starting off with 5 gallons at a 70/30 mix of fuel to oil. I'll see how it likes it so in case it doesn't, it's only 5 gallons I need to drain out of the tank lol.
So the truck is officially running on used oil and the fuel mix.
I only mixed up around 4 gallons for now. My tank was basically on E, so it's mostly the new fuel in there.
I did change my mixture though. I went mostly used oil and then only used the fuel mix to dilute the oil so it was a little thinner.
Truck seems to run about the same as before, if not a touch smoother actually. I do have a very slight blue smoke from the exhaust. I only noticed it because I looked under the truck to grab a funnel I dropped and I saw the little bit of haze.
I will run this batch for a day or so to see how it does, and if everything is still good, I'll do half a tank of it
Scored a set of mirrors off a guy I work with. They need to be cleaned up and painted, but I was going to paint them either way.
I'm hoping to get them sanded down and primed tonight. I need to get some more of the black paint that was used for the wheels and bumpers. Hopefully I can match it decently enough. I have the old can of what the guy used, so I should be able to get the same color.
I'll post some pics before and after I get them cleaned up.
Well my plans changed last night unexpectedly so I didn't get to work on the mirrors like I wanted.
But I also have a line on some turbos, intakes and exhaust manifolds off a 6.5 motor that my buddy in Ohio has. I'm buying those off him and will rebuild the two turbos, keep the better one, and then sell the rest to likely pay for the whole setup and then some.
Not sure when I'll attempt the install, but I'm going to start soaking the manifold bolts now and spray them a few times a week so hopefully the bolts will come out.
Mirrors are being media blasted today, so I should be good to get them primed tonight. I was going to just sand them down, but the media blasting is much easier and will remove any traces of rust and surface impurities.
My main hope is that the media isn't too aggressive and puts pits in the metal. Not a huge deal if it does, but it would add some extra steps.
Mirrors are all painted and installed. I wanted to match the paint that is on the bumpers and wheels, but couldn't find any locally. I need to pull the mirrors off again anyway so I just gave them a coat of satin black for now.
They look much better on there. Visibility is obviously reduced from the other mirrors, but that was expected haha.
