Expert's Assistant chatimg
Customer: Hi,

I have an older Sullair 160 Rotary Screw with Diesel John Deere 179 cu. in., 3 Cyl that ran great a few years ago. Now, it turns over very slowly but, won't start. It has a new starter and new 870 CCA battery and still won't start.

Due to lack of indoor storage availability, it was stored outside. The first year or so it was covered with tarps but, the tarps weathered away.

I'm retired now and am merely trying to liquidate some of my former business assets to try to supplement my Social Security. Do you have any suggestions on how I can restore this machine, without costing more than it's worth? Thank you very much for your help.

Hi my name is XXXXX XXXXX I may be able to help you out, Can you tell me if the engine is producing smoke while you are cranking it, and do you possibly have a clamp on ammeter that you can measure the cranking amps with? My first thoughts are that water and rust has gotten into the cylinders or into the compressor that is causing excessive drag.




I did not see any smoke coming out of the exhaust stack when cranking the engine.


No, I don't have a clamp-on ammeter and I wouldn't know where to connect it if I did.

A friend of mine told me there could be a possibility of corrosion on the cylinder walls, etc., causing excessive friction on the piston rings. What else do you have? Thanks.



Don, I feel that your friend could be right about corrosion on the cylinder walls causing the drag, but the fact that there is no smoke coming from the exhaust indicates to me that there is no fuel being injected into the cylinders, have you bled the fuel at the fuel injection lines?



No, I haven't.

Ok, then let's bleed the fuel system, use the hand priming pump and open the bleed fitting on the fuel filter and make sure that fuel runs out when you pump it, close the valve and loosen the fuel injection lines at the fuel injectors and crank the engine, fuel should sprut out of each line when the pump delivers fuel to each injector. If you still don't get smoke after bleeding the fuel system, then the rings may be collapsed and not allowing the cylinders to build compression. Try this and let me know what happens and then I can explain how to loosen the pistons if necessary.

This will take me a few days. My Sullair is not here right now but, when I get it back, weather permitting, I'll try doing what you suggested and go from there. Thanks.

Ok, that's fine, I'll be waiting to hear for you. It sounds like you may be on the east coast, good luck to you
