Sullair 185 Model# 185DP0CA keeps shutting down

'Inherited' a Sullair 185 (age unknown)

Starts up great when cold and begins to build pressure up to 120 psi max...

Runs for under 3 minutes and shuts down(restarts immediately though)

No idiot lights etc...

Oil level, fuel etc is good.

Help!

Fixed and running

Turned out to be the oil pressure sending unit! Replaced and works perfect... Thanks to all that helped.

To Doug from s.d. - re shutdown of 185
by: Mark

It shuts down quickly, no slugging.

But it does it much sooner now.

Thought it may have been low on compressor oil and sure enough it was quite low. Threw a gallon in and it was not enough to show on the sight glass.

Going to get more oil and even though it shuts down fast I WILL check the filter!

Fuel filter?

And how does the shutdown occur? Like a turn-off, or a lug-down?

Sullair 185 Bypass or warm up valve problem

by Terry (turboterry)

Sullair 185 1990 model bought used and not running. Builds air pressure as long as you push and hold in the warm up valve (bypass)on the gauge panel but goes down to 50lbs as soon as you release the button. Replaced the regulator with no success. Has air pressure going to warm up valve so I am thinking it may need replacing? I believe it is a 5 port valve. Can't seem to load a picture but I can send one if anyone is interested. Thanks in advance.

Does the engine keep running through all this? If not, what kills it?

If it keeps running, does it speed up and down at all?
