I'm probably going to pull the trigger on it but it's to far of a ride for my truck at this point and I can't seem to find someone to take the ride with there truck. Frustration is setting in! Oh and I was going to use the new plasma cutter today lol my dumbass it's 220.... So is my compressor and I only have 1 outlet

When do you need both at the same time?

Clutch, I've not worked on an Airman, I did find a maintenance manual online and the air system looks fairly simple and the parts which may cause problems (rubber o-rings in the unloader, regulator) look fairly simple and basic. In the as it says it won't shut down automatic, find out if it's got an ECM or not. The schematic I saw for that era machine showed shutdown relays, so that may be fairly simple but still a barganing point. If you can run it make sure the air comes out dry, any oil out the discharge ports is a sign of a bad separator filter, on our compressors a separator filter can run hundreds of dollars. Also a separator filter usually gets changed every 1000 hrs, so if there's no record of when it was changed use that as barganing. Usually on the discharge tube (from compressor itself to large receiver tank) there will be a 2 wire temperature sender. It should break power to the fuel pump if the compressor gets too hot, if you can find it, with the engine running I would pull 1 wire off and see if the unit dies. If it does, the safety shutdowns are working, If it doesn't, someone bypassed the wiring and it has a heating problem. Also check the radiator and cooler and see if they're packed with crud.

I may need to have one of you guys hit a junkyard for me I can't find a 77-80 parts truck anywhere around here and these parking brake parts are impossible to find.
So in your travels (remember keep it cheap lol) it's supposed to have steel brackets that just hook in the frame and hold the cables up because it takes a cable that loops all the way up and back from the back to the forward cable and 2 rear cables on each side I can buy cables but the brackets and connecting Hardware seem elusive so keep me in mind please. I'd like to get the parking brake parts installed before I fix the exaust and believe me I want to do something about the exaust!

Are these what you are looking for? If I have to cut rivets, that will take some time, but the bent wire piece on the passenger side is yours for the asking. Just need to bend it a little to uncapture it off the bracket, then lick a few stamps.

What he said. I would also look into why the fuel shut off is not working. Is it the selinode or has it been bypassed for some reason? What engine is in it? If it is a Perkins, Duetze, or Cummins awsome. Older John Deere are ok newer one's have issues. I am familiar with the Atlas's.

I need them bolth plugged in to plasma cutter it runs on air and 220 and the compressor is 220

Cool will do I talked to him and he said there's a solenoid that shuts off the fuel when you turn off the key and that's what's bad.

Will do I'll keep you guys both posted when I check it out tomorrow

I can crawl under the K30 tomorrow and see what is there. I think all the cables are in place so you can see how everything routes.
