LEGEND FOR FIG. 12
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.
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.
