7–9 T-3637.8.2 Compressor DisassemblyWARNING!Before disassembly of any external compressor component make sure to relieve possibleinternal pressure by loosening the bolts and tapping the component with a soft hammer tobreak the seal.WARNING!Removing the compressor motor press-fit stator in the field is not recommended. The rotorand stator are a matched pair and should not be separated.When disassembling compressor, matchmark parts so they may be replaced in their same relative positions (seeFigure 7.5). Refer to Table 7–4 and Table 7–5 for compressor wear limits and bolt torque values.a. Place the compressor in a position where it will be convenient to drain the oil. Remove the oil fill plug (seeFigure 7.5) to vent the crankcase. Loosen the drain plug in bottom plate and allow the oil to drain out slowly.Remove the plug slowly to relieve any crankcase pressure. Some units have a plug in the bottom center ofthe crankcase, which may be removed for draining the motor end more quickly.Figure 7.6 Exploded View of Valve Plate1. Cylinder Head Gasket2.
