Hi someone can help me I have I rockford 6 gallon air compressor

The regulator isn't working.

NO. It goes in the crank case of the compressor. There is a plug that takes a wrench to remove to put the oil in.

nothing
it is the regulator that is faulty

A blocked air filter will have this effect. Remove the air filter and try again If the compressor starts pumping air you have found your problem. If not the valves could be stuck open, shut or broken If there is oil or a lot of air being blown back out the oil filler hole the rings have worn or have been damaged. Either way if taking the filter off doesn't work someone has to pull the pump down and see the problem. I would check Bostichs site to see if there are parts available but if you have a tradesman you can trust get them to quote to fix.

The best way to determine how the compressor is doing is with a pump up test. Time how long it takes the compressor to pump up from one pressure to another. If you know the tank size, you can then compute the air delivery of the compressor:
CFM=(Pressure Change / 14.5) x (tank size in gallons / 7.48) x (60 / time in seconds)
I'd recommend start timing about 40 or 50 PSI and pump up to shutoff.
If your compressor has no aftercooler (it probably doesn't) this should read a bit higher than your 7.8 CFM FAD because the air will be hot, but it will get you in the ballpark.
If compressor seems OK, tool could be worn or fed too high a pressure (if you put 120 PSI to a tool, it will use quite a bit more air than it is rated for - they are usually rated for about 90). If your compressor maintains pressure at 95 or 100, but doesn't gain ground, everything is probably OK. I'd just add a pressure regulator to maintain 85 or 90 to the tool in that case.

Compressor oil is less demanding then cars, but car oil works fine. Normal 1W-40 would probably work the best.
You would hardly ever have to change it either, because there is no water, soot, or acids produced in a compressor, as there are with a car.

PRESSURE REDUCER valve

your motor start capacitor is bad, look for it on side of motor and for signs of bulging,leaking heat stress condition

I have a Kobalt 60 Gal 3.7 hp air compressor. Send me your email address and I'll make sure you get your schematic. Hope this helps! [email protected]

Try DW40, Q20 or another penatration flued. It might be that the aluminium oxidized over time and made the surfaces powdery. If there is a rubber seal inside it would be brittle and not doing it's job any more.
