Anyone run a compressor off the engine?

I have a Holset 8. 5 CFM air cooled air compressor on my Cummins powered Ford. It is direct mount with the power steering pump mounted to the rear of it. It works great.

I had one on my 10t GMC, but it only built 65psi of air (thanks to a misterious leak). Try driving that and stopping with out the parking brakes dragging.
 
Not possible actually!!

Just wonder if anyone has an air compressor driven by the engine? If so how did you set it up?







I think you'll be hard pressed to find anyone running a 2nd gen truck with a compressor directly driven by the engine. Yes, you're absolutely right in thinking that some applications of the Cummins diesel engine do support such a configuration, however, available space in the engine bay in the Dodge RAM configuration is limited and right where you would expect to run a compressor, Dodge have used this precise location to provide a HD rear engine mount instead.



You might want to try searching back in this forum to early 2001, when this was kicked around a lot for the full information. Good luck!!

Kilby enterprises makes a kit for a York air compressor!



Jeff H (thread starter) has a 1995 Cummins/Ram in his signature. I believe the Kilby Enterprises (onboardair.com) Cummins/Ram York compressor kits don't include the twelve valve engines.

The Cummins set up drives off of the same gear that drives your p/s and vacuum pumps. If you have the vacuum brakes on your truck it becomes a real hassle. If you have the Hydra-boost set up it becomes a little easier. You have to remove th p/s and vacuum pumps. Put in the compressor then adapt a different p/s pump to the compressor. The Dodge is too big and hits the motor mount.

I was assembling the parts to do it when I discovered the size problem. I went with the Kilby On-Board Air system. It does everything I want to do. I run my system so that the compressor can come on at any time the engine is running. I have air-ride bags on the rear with auto leveling valves, and my horn is connected to air horns. I also use the air for impact and air grinders at the race track. The system has been able to stay up with me. I do have a 4 gallon air tank and a throttle kicker that when I amworking at at a jobsite will bump the engine to 1500 rpm when the compressor comes on.
 
Years ago, I bought a engine driven compresser for my 92 Dodge. The only unique part was a modified pully that added a "V" belt pully to the front of the fan drive for the York compressor and a idler for belt tension. It works real great, but the York takes up a lot of space. Would rather have a Sandon.

Jeff,

I called Onboard air a couple of years ago about the second gen trucks from 94 to 98. 5 and the only reason he said that he didn't make them is because he hadn't had that model in his shop long enough to fabricate the mounts for the compressor. He needed one for about 3 or 4 days to do so. So there we are.

I believe last year there was talk that he was gonna start fab. on the 12V brackets.
 
So basically for a 12 Valve, an Electric Air Compressor is the most reasonable way to go? I want to get one myself to run some locomotive horns, but cannot find one for the motor also. . Anyone know of a good source for 12 volt air compressors (High Vol)?

Chris, your right about the electric (115v) compressor is the easiest and cheapest way to go. My system has a 115v Senco compressor installed in my in bed tool box. Cost $99. 1500 watt inverter under drivers seat from Cosco for $84. 5gal tank, $20. Misc wiring and air hose and fittings and you have a 125psi working system for about $225. There are cheaper 115v compressors out there also. I seen one at Lowes for $69 the other day.

I use mine mostly for the exhaust brake and the air horns, but I also carry a 50ft hose in case I want to air up my trailer tires, or just blow a little dirt off of something.
