2.4 — <strong>Service</strong> ProceduresThe service section covers replacement of valve platesand gaskets, service to the bearing head assemblycontaining the oil pump, and a clean-up procedure tofollow in case of motor burn out. Most other internalservice requires replacement of the compressor.REMOVE, INSPECT AND REPLACE CYLINDERHEAD AND VALVE PLATE ASSEMBLYTo test for leaking discharge valves or blown cylinderhead or valve plate gaskets:1. Pump compressor down.2. Observe suction and discharge pressure equalization.If valves are leaking or a gasket is blown, thepressure will equalize rapidly.Maximum allowable discharge pressure drop is 3 psiper minute after initial drop of 10 to 15 psi in firsthalf minute.New reed valves may require 24 to 48 hour run-intime to seat completely.A compressor bank (head) with a blown gasket canalso usually be detected by touch since the headtemperature will normally be much hotter than a bankwith good gaskets.3. If there is an indication of loss of capacity, anddischarge valves are functioning properly, removevalve plate assembly and inspect suction valves.NOTE: This test procedure is not applicable tocompressors equipped with pressure actuatedunloader valves due to rapid pressure equalizationrate. Inspect suction and discharge valves by disassemblingvalve plate.32
