Question about Air Tools & Compressors

1 Answer

I have a very old Westinghouse Air Brake 1BYC, Type Y, maybe model # 209878, air compressor. It is very slow to even pump 80 psi and then the pressure will leak completely to zero. I think wear of the rings and piston may be the cause. Can this compressor be repaired? If so about what would be the cost?

If there is no external leakage, then air is probably slipping back past the valves. If the cylinders and rings are good, a valve change may fix it. There are still aftermarket parts available for these machines. As a rule of thumb, a rebuild with rings, gaskets, valves, and bearings usually runs about $100 per horsepower.

Have a old (1950's guessing) westinghouse air compressor. Pumped it to 150 psi, I shut off, air was coming out of air intake and had pressure in the crank case.


replace the non-return valve in the pipe at the tank connection
air out of intake is poor poppet/read valve seating and pressure in the sump is the tank air leaking back and down past the rings
150 psi is excessive and not good for the compressor so adjust it back to 100 -110 psi

Can I get 80 psi with dials set at 40 psi


this compressor should be able to fill your tires to 80 psi. Look for a pressure switch and adjust it so the motor shuts off at a higher pressure. Do not exceed 100 psi.

My kobalt 80 gallon air compressor won't turn on


BE CAREFUL! Jump the pressure switch and see if it starts. If so, replace the switch. If it doesn't start but hums, cut the power and try to turn the compressor by hand. Free it up if possible. If it does not hum, look for a reset on the motor or a blown fuse or breaker.

Why does the safety valve go off before the pressure switch on a porter cable 80 gal air compressor


The maximum pressure on most small compressors is 10 bar or 1000kpa which is about 145 psi in the old language most safety valves are set to 150 psi. I suggest you get some one to reduce the pressure switch setting. Running a compressor at elevated pressures does not give you any more air. A reasonable pressure for small compressors is 120 psi

Air compressor slow to build pressure, and noisy.


All large air compressors are very noisy.

How long it takes to come up to pressure depends on the size of the compressor piston(s), how fast they are running and the size of the air tank attached to it. (and if the tank or hoses have leaks)
A 20 gallon tank could easily take 10 minutes to get all the way up to 120 psi. 120 is very high, and probably the limit for the compressor. Depending on what you're using it for, try dropping the setting to say 80-90psi.

Air compressor will not restart after it builds pressure and pressure drops to 80 psi


Make sure the power cord is plugged into an adequate extension cord if one must be used. Never less than 12 gauge wire.

The start/run capacitor may need to be replaced.. If there are any ball check type valves, make sure they are not worn or sticking. they would be on the output of the compressor head itself.

T wo suggestions. 1- check the check valve located in top of the receiver tank by letting the unit pump up to 50 psi. shut it off and loosen the copper tube at the HP cylinder. if no air blows out the check valve is good. If it's bad it will blow until it empties the tank. If the check valve is bad replace it. 2- Tighten the drive belt. If neither corrects the problem remove the guard and rotate the pump by hand. If it's hard to rotate you have a pump problem.

I am almost sure what you have is only a single pump and should only rut out 125 psi tops. you should not exceed this with a pump of that type. If it is a 2 stage pump (one large and one small cylinder) they can commonly go to 175 psi. But as always check to see what the maximum pressure your tank was certified and do not ever exceed it.

Howdy, I just acquired an air compressor, ''Westinghouse Air Brake Co., Type Y 3YC, SN 136848. I am wondering about parts motor config, cfm output, psi, etc. It appears to be a 2 stage & I'm thinking...


We have a Westinghouse 3YC air compressor. The safety relief valve in the line between the two compressors started "popping off" recently. The compressor seems to be working fine. Is this a problem only with the relief valve or could there be a symptom of a more serious condition that we should be attending to? The valve is stamped 60 max which I assume is 60 psi. Is this the correct size. The tank pressure is set for125 psi. The tank relief valve is marked 250 max.
