The main tank pressure will only go to 30psi?
by Bill H
My main tank air pressure will only go to 30psi no matter how long the pump runs.
Everything sounds ok and it pumps from 0 to 30 normal enough.
I can't detect where the air is going if not in the tank.
I read Bill's 4 things to check(there are about four things that could be the cause. Bad power supply, intake valves, pressure valves, gasket failure or piston seals.)
The power supply is good, and I pulled the head and piston rings and seals looked good. I am not sure how to check the valves. I thought it might be a pressure regulator. Anyone have help?
Howdy Bill. A pleasure to see that someone actually reads some of my scribblings! :-)
When you say pressure regulator, I take that to mean your compressor pressure switch, as that is what controls the on/off of your compressor based on the tank pressure it sees.
If, at 30 PSI, the pressure switch is not tripping the compressor to off, and the motor is still running, then power is still flowing through the pressure switch, the pressure switch is working. It just isn't seeing the cut out pressure necessary to allow it to trip and turn the compressor off.
That it pumps to 30 PSI before not going any further strongly suggests to me that you have a gasket, likely between the low and high pressure flow paths inside the pump, that lets go at that pressure.
As to the valve plate, the reef valves need to be examined to see if they are in good shape. Another check is the intake port when the compressor is running. Is there good strong suction or is air huffing out of there while the compressor is running?
Will not pump up car and truck tires?
It runs good and builds up pressure to 100 psi but I cannot get the tires to accept the air from the line. I just do not under-stand it.
I hear the frustration in your posting with a fully charged air compressor but no air going into the tire. So sorry you are having the problem, but you are not alone.
There is a clear path for compressed air from the compressor tank to the tire. Each of the components in that compressed air flow path need to be checked to find which it is that is preventing air from getting into your tires.
If you visit the Troubleshooting page, click the link to No Air From Hose for help in diagnosing this problem and suggestions for finding out if it is the regulator, the discharge coupler or just what may be preventing air flow.
And, you need to make sure that your tire chuck works and the valve in the tire works too.
Model # 92504 - size of pulley & shaft?
I have a Model # 92504 central pneumatic air compressor that does not have the large belt wheel (pulley), belt to connect large belt wheel to motor pulley and the bolt to mount the large belt wheel onto the compressor pump shaft. Does anyone know what size of each of these i need and where I can purchase them?
I hope someone can advise, though, if you have not talked to HF, that's the place to start. Central Pneumatic air compressors are their house brand.
model 94724 trips breaker & compressor won't start
(Oceanside, CA, USA)
When the switch is turned on, it pauses a moment, then trips the safety button. The compresson does not start.
Could be a bunch of things, Don.
Please see the page under Troubleshooting about compressors that don't start, do the checks referred to, then comment here with your findings.
