i was originally using 2 single strands of the smaller #40 chain. I didn't realize how impossible it would be to get equal tension on both chains. I was unable to apply proper tension to both chains at the same time. Apparently chains stretch. Without proper tension, one of the chains were always unhappy. I tried driving around on a single 40 chain, but it kept breaking. In one day of R&D i broke the chain 3 times without even abusing the truck.

I finally got tired of monkeying around with something with such a high failure rate and decided to upgrade. The worse part is that it was far cheaper to buy the #60 chain and sprockets than it was all the pieces of the puzzle for two separate #40 chains. Live and learn.

I got the a/c compressor converted to a air compressor last nite. It can be used to keep the cylinders for the rear suspsension up to pressure as well as filling tires and the like. a/c compressors don't last too long in this application, but they will out perform my 7 hp 220 volt compressor in the shop.

What A/C compressor did you use? I use a york V2 from the late 70's chrysler products, I use synthetic oil in the compressor and controll on/off pressures with an adjustable Square D pressure switch from Graingers, a checkvalve after the compressor and a 10# fire extiguisher bottle complete the system, an adjustable regulator allows for the adjustment of ride stiffness and limiting straps to control ride height.

i'm using the stock a/c compressor for the 1990 k2500 HD 4x4. The problem is that there isn't an oil sump inside, i believe that the compressor is supposed to be lubricated with the oil/freon mixture which it no longer has inside. I think i'm gonna try setting up an auto-oiler on the intake to help keep a lkittle oil inside. Destruction of the compressor is inevitable i believe, but i had all of the parts laying around for the conversion.

For a pressure cutoff switch i used one from an old air compressor. I also installed a 150 psi pressure relief valve.

When that compressor finally gives out, i have a used air brake compressor for a big truck. mounting will be easy, but i have to connect an oil line for lubrication, and coolant lines. It's a pretty fancy setup.

Are you sure that there is no sump? check the service manual or a good independant a/c shop, I understand that the lubrication is added thru the charge port into the system, but I was under the impression that the oil found it's way to the compressor sump because it was liquid while the refrigerant is gaseous until it is compressed on its way out of the compressor, sure some oil travels in the refrigerant, but if you can keep oil in the sump the compressor should live a long time. O yeah; make sure to filter the compressor intake, I tapped into the engine aircleaner.

Get the part number off your compressor and use the search function on various 4wd forums like http://www.pirate4x4.com As much as I hate all the cyber wheelers on a lot of those sites, you can often dig up atleast one useful thread. I'm sure someone will have already done the R&D for you. I'm lucky in that Front Range Offroad makes a whole kit to convert the Toyota compressors over including the oiling.

i have the truck in a heated garage, and hopefully will get her painted this week.

HERE ARE THE LATEST PHOTOS





still need to re-attach the truck "bed" as seen in some earlier photos like the one below


i'd like to get her out to the mounds before they close in the next couple weeks. like most projects, she's overbudget and behind schedule

Well...it's official. I couldn't readily identify it as being Chevy based on the trail anymore. Not without stopping and inspecting anyway....and if I ever ran into that on the trail I might just have to harass you until you let me take a peak.

Let me know when you take it to the mounds. I got that Blazer I can bring out there. I cant be too hard on mine though because I'll probably drive it out there and back.... unless I find a trailer to borrow.
