Compressor Leak Test
- Remove compressor. Connect Adapter Hose (J-22124-91
) to air drier fitting. Connect Pressure Gauge (J-22124-A
) to adapter hose. Apply shop air pressure through service valve on pressure gauge until pressure is 100 psi (7.0 kg/cm2
).
- Using soapy water solution, check for leaks around air drier cover, air drier "O" ring casting bore, edge of cover gasket, edge of solenoid valve housing and air intake and exhaust opening in head casting. See Fig 1
.
- If leak exists at compressor head bolts, tighten bolts to specification, and recheck for leaks. See TORQUE SPECIFICATIONS
table. Remove pressure gauge.
