Fig. 24
1. Apply a thin film of clean
refrigeration oil to each side of the
valve plate gasket (Fig. 24).
2. Place
the new valve plate
gasket in position on the crankcase so
that the crankcase dowel pins go
through the dowel pin holes in the
gasket (Fig. 24).
3. Place the valve plate in position
on the cylinder so that the dowel
pins go through the dowel pin holes
(Fig. 24).
4. Apply a light film of clean re-
frigeration oil on each side of the
cylinder head gasket. Then, place the
gasket and cylinder head on the
cylinder with the dowel pins inserted
into the dowel pin holes in the
gasket and
head.
5. Insert the two longer cap screws
in the two center holes of the cylinder
head. Then, insert the remaining cap
screws in the holes around the edge
of the cylinder head. The four 12
point head screws should be inserted
into the four holes closest to the
service ports.
6. Tighten all head cap screws
until they contact the head. Then
torque the two center screws to 15-23
ft-lb
.
7. Tighten
the
remaining cap
screws in a pattern so that the cap
screws diagonally opposite each other
are evenly tightened to 15-23 ft-lbs.
After the cylinder head has been
installed 1 /2 hour, retorque the head
bolts to 15-23 ft-lbs.
8. Inspect hose connections and
Schrader valves
for
damage. Replace
if necessary.
9. Check compressor oil level.
Add or remove oil as
required.
10. Evacuate
and
recharge
the
system.
