Question about Air Tools & Compressors
I have a 60 gal craftsman air compressor that will only build 92 psi. Just runs and runs, never buillding enough pressure to trigger switch. Pulled apart pump, everything looked good. Rings and cylinder walls were perfect, so i replaced gaskets and reasembled. No leaks anywere else, not sure where to go next. Very little use and only 3 years old. Help?
Most compressors with the problem that you are having suffer from leaking valves. As in a gasoline engine, leaking valves will lower efficiency. Valves in a compressor are in the form of reeds that seal against valve plate. Leaking reed valves or gaskets will increase the discharge air temperture. Inspect these parts with a magnifying lense. Look for evidense of wear or leaks. Also look for signs of air leaking from one cylinder to the other thru gaskets. Replace valve plate as necessary. Simple test, as your compressor is filling, check the intake for strong suction; as it neers the 92 psi mark suction will probably deminish if you have leaking valves. If suction remains strong at 92psi then you have a leak at the discharge side. Check with soapy water on all parts. Good luck
