Disassembly and Reassembly

NOTE: Parts shown for reference only. Valve
plate is sold only as assembled unit.
Repair
NOTE: Valve plates must seal completely or the
compressor will lose capacity.
1. Inspect the cage, ring valve, valve spring, and
retainer for wear or damage.
2. Valve plates may be tested by pouring clean
fluid (Stodard solvent, which must be
nonchlorinated) into the depression of the
valve plate. The solvent should not leak
through. If the valve plate assembly is worn,
damaged or leaks, replace it with a new
assembly. Remove all traces of solvent before
installing the valve plate assembly.
Installation
1. Apply clean refrigerant oil to the new O-rings
and install them in the compressor body above
the cylinder sleeve. See “Figure 20: O-ring
Location” on page 33.
2. Apply clean refrigerant oil to the valve plate
assembly and install the valve plate assembly.
Turn it slightly to prevent binding. See
“Figure 19: Valve Plate Removal or
Installation” on page 33.
3. Install the cylinder heads. See “Installation”
