the hole for the oil inlet tube in the cylinder assembly
is aligned with the reservoir hole in the shell, and
reassemble the oil inlet tube and
“0” ring.
2. Assemble suction reed valve disc to rear of cylin-
der assembly and align with dowel pins, suction port,
and discharge port of cylinder assembly.
3. Assemble rear discharge valve plate to rear of
cylinder assembly and align with dowel pins.
4. Reassemble inner and outer oil pump rotors so
that the sides previously identified are in their origi-
nal location, and then position oil pump outer rotor
as shown in Figure
9B-157.5. Generously coat with No. 525 viscosity oil new
“0” ring and install in shell (see Figure shell to head
9B-157).6. Coat Teflon sealing surface of rear head with No.
525 viscosity oil, mark with pencil on side of rear
head the lpcation of the dowel pin holes and reassem-
ble onto compressor.Figure
98.157 Positioning Oil Pump Outer Rotor
It may be necessary to repositipn oil pump outer
rotor slightly in order to install rear head. In addi-
tion, if dowel pins do not engage’ holes in rear head,
grasp front head and rotate cylinder assembly
slightly (see Figure
9B-158).7. Assemble new nuts to threaded shell studs and
torque to 10 lb. ft. If pressure relief valve has been
removed, reassemble using a
riew pressure relief
valve gasket.
8. Reassemble new lubricated suction and discharge

“0” rings into suction and discharge ports of rear
head.9. Reassemble shaft seal onto front of shaft andwash plate assembly. Do not reassemble clutch
drive plate at this time.
Leak ‘Testing Compressor1. After the shaft seal pressure test has been per-
formed, change the test circuit to the configuration
shown in Figure 9B-160.
2. With hose attached only to high pressure side of
Leak Test Fixture J-9625, open high pressure valve
to charge high pressure side of compressor. As soon
as high pressure gage stabilizes reading, close valve.
If high pressure gage drops back immedaitely when
valve is closed, an internal leak is indicated. Correct
leak as necessary.
If an internal leak is indicated, the leak may exist
about the head sealing surface or Teflon seal,
dis-
charg,e tube, shell to head “0” rings, or suction valve
reed discs.
3. Remove drain screw from shell and add No. 525
viscosity oil as specified.
4.
R~eassemble pulley assembly, and coil and hous-
ing assembly onto hub of front head.
5. Complete reassembly by installing clutch drive
plate onto hub of front head. See Figure 9B-164
disassembled view of compressor.

Functional Test Procedures1. Place transmission in park for automatics and in
neutral for manuals. Apply hand brake.
2. Turn blower switch to HI position,
3. Turn temperature switch to MAX position-.
4. Run engine at 2000 RPM for ten (10) minutes with
car doors and windows closed and the hood up. Place
a commercial high volumn fan in front of condenser
if head pressure should exceed 250 psig.A commercial high volumn fan should be placed in
front of the condenser at high ambients to bring the
pressures to within the limits specified in the Func-
tional Charts. When testing the Opel 1900 and
Man& a thermometer should be placed in a position
to read the temperature of the air discharging from
the right-hand A/C outlet. When testing the GT, a
thermometer should be placed in a position to read
the temperature of the air discharging, from the left-
rear
,A /c outlet.
