ingersoll rand 185 cfm shuts off when cold using jackhammer

by Dennis
(phila pa)

When I start my air compressor it runs fine cold it shuts off when I use the jackhammer if I dont let the compressor warm up. Its a diesel.If I try to restart it it clicks. Then I have to unhook the battery or let it sit before it starts again.

Dennis, when you start using your jackhammer, it uses a lot of air. The drop in pressure from the compressor should toggle the throttle up to build more air flow. It sounds like the diesel engine itself is reacting to the demand for acceleration by stalling out.

The last time I heard a clicking noise when I tried to start a motor, the battery was dead.

I am open to suggestions from other readers on this one. I'm stumped.

trying to find a part for IR compressor
by: carl

Air compressor leaks oil from the air end that is bolted to the engine.

air end was removed and we found a damaged seal there. There is no part # on the seal so i cannot order this seal.

Does anyone have a schematic of this area or a part #

I/R P185 tow behind won't restart

by ron
(brookpark oh.)

We have several p185wjd I/R mobile air compressors.

the one in question starts and runs fine but wont restart unless the air pressure is drained off.

the engine cant turn over while the screw is trying to build air.

bleed the air off and it starts fine.

could the unloader valve be stuck? other than that it builds air and cycles fine.

Joy compressor problems
by: Vic

I have a Joy tow-behind compressor. When I first start it it needs choke for a while, then I can close the choke. When I turn the valve from start to run it immediately kills the engine, even when it is fully warmed-up. It will however run when I choke it, but not very well. Any thoughts will be appreciated!!!

2011 p185 tow behind

by Anthony
(jacksonville N.C.)

I have recently purchased a ING Rang p185 runs great produces air when you push the warm up button on control panel the problem is once you have opened the valve to produce the air then shut the valve off and turn it back on it won't build pressure!

after I hit the warm up button again it builds pressure I open valve air flows I close valve and open it again and it stops, the warm up button on control panel has been replaced but i'm assuming it is another actuator of some sorts

plz help I have no pics at this time.

ingersol rand 185 diesel road compressor

by arthur campbell;
(northern irelanduk)

hi there,this is about my faithfull ingersol rand 185cfm diesel road compressor,

i have not used this 1990 road comp for about 3 years although i did start it up every so often just for mechanical reasons,now after 3years i need to use it again,

i started it up easy,first time starter with plenty of pressure but there is oil in the outlet which was not there before i stopped using it,also the air seems to be slightly warmer,i would be delighted if you could help me with some advice on what might be the problem,thank you so much in antisapationarthur

Arthur, if you are seeing a greater incidence of oil in the compressed air discharge to the line to the air tools, and then, at the tools themselves, then I would look to the piston seals allowing oil blowby into the air which is being pumped into the lines.

You may need a motor mechanic to address this issue.

Cheers,

Bill

Oil in discharge
by: Ron Belt

Hi, Ron with Air Compressor Service.

All rotary screw air compressors have a special filter in the oil sump. Air/ Oil Separator. This filter removes the oil from the air when it leaves the screw and is located inside the oil tank sump.

Additionally, there is a 3/8" steel suction line that feeds through the top lid clear down to the bottom of the filter to suck any oil that gets through the filter back to the screw. The suction scavenge line many times has an inline check valve right where it comes out of the lid. So, either the filter is bad or the check valve is stuck.

Start with the check valve. Flow is away from the oil tank and checked so oil can't come back into the filter. There is an arrow on it so make sure it is pointed away from the oil sump.

Separator filters run $160 to $250.
