Three Allen head cap screws hold capacity control valve in place (Fig. 14). Remove screws using a cut-down 3/16-in. Allen wrench, and pull valve from cylinder head.

Remove same number of piston plugs from replacement compressor as number of unloaders supplied with original compressors. Three Allen head cap screws hold piston plug assembly in place. Remove flange cover, gasket, spring and bypass piston plug (Fig. 15). A tapped hole is provided in piston to allow it to be pulled out. Hole has same thread diameter as cap screws removed above.

Cylinder Heads — Disassemble cylinder heads by re- moving cap screws and prying up on side between cylinder head and valve plate to break heads loose from valve plate. Do not strike cylinder heads to break loose.

Check heads for warping, cracks and damage to gasket surfaces. When replacing cylinder head, torque cap screws 30 to 35 lb-ft to prevent high to low side leak in center portion of cylinder head gasket.

Service Replacement Compressors — Replace- ment compressors are not equipped with control valves. One or both side bank cylinder head(s) is plugged with a spring loaded plug piston assembly. Compressor will run fully loaded with piston plug(s) in place.

Transfer original capacity control valve(s) to replacement compressor (ensures proper valves are used with correct set- ting). For sealing purposes, install a plug piston assembly into each cylinder head of original compressor from which a con- trol valve was removed.
