(1)
Verify suspected damage to reed valves.
(a)
Disconnect the intake flex hose from between the cylinders.
(b) Remove the intake silencer from the top cylinder.
(c) With the compressor running, check one cylinder at a time by
placing your thumb across the open end of each cylinder elbow or tee.
(d) For the top cylinder, use three fingers to block all parts of the tee.
(e) Verify there is a strong suction at each cylinder. If you feel little or
no suction, either the inlet or outlet reed valve is defective in that cylinder.
CAUTION:
If any reed valves are broken, you must locate all pieces of the reeds
and remove them from the compressor. These pieces may be anywhere
within the tubing and the connecting system.
(2) Remove the motor and compressor assembly. In order to reach the
reed valves, you must remove and disassemble a portion of the motor and compressor
assembly.
(a) Remove the motor and compressor assembly from the transit case.
Refer to paragraph 4-2a(1)--(3).
(b) Remove the intake flex hoses from cylinder to cylinder (hose
clamps secure flex hoses at each end).
(c) Disconnect the cable from the motor box to the capacitor at the
connector on the capacitor.
(d) Disconnect the cable from the circuit breaker to the fan at the
connector.
(e) Remove the four nuts, lock washer, and washers from the bolts that
secure the motor and compressor assembly to the base plate.
(f) Lift the motor and compressor assembly from the base plate. (Note
four spacers under motor and compressor assembly.)
(g) Remove cylinder assemblies by removing four bolts and lock
washers from each cylinder head.
