DISASSEMBLY OF TRANSFER RIGHT CASE
1. INSPECT OIL PUMP OPERATION
Check that the oil pump turns smoothly with oil pump
driven gear.
2. REMOVE OIL PUMP DRIVEN GEAR STOPPER, OIL
PUMP COVER, DRIVE ROTOR AND DRIVEN ROTOR
(a) Remove the three bolts and oil pump driven gear
stopper.
(b) Pull out the oil pump cover, drive rotor and driven
rotor.

Checking of Refrigeration System with Manifold Gauge
This is a method in which the trouble is located by using a manifold gauge. Read the manifold gauge
pressure when the following conditions are established:
(a) Temperature at the air inlet is 30 ± 35
°C (86 ± 95°F)
(b) Engine running at 1,500 rpm
(e) Blower fan speed switch set at high speed
(d) Temperature control lever set at cool side
HINT: It should be noted that the gauge indications may vary slightly due to ambient temperature condi±
tions.

Allow to stand for some time
and then restart operation to
determine if trouble is
caused by moisture or dirt.
If caused by moisture refer to
procedures¿Step 2 on
,page AC±19.
If caused by dirt, remove
expansion valve and clean off
dirt by blowing with air. If
unable to remove dirt, replace
valve.
Vacuum purge and charge
new refrigerant to proper
amount.
For gas leakage from heat
sensing tube, replace
expansion valve. Refrigerant flow obstructed by
moisture or dirt in refrigerant
freezing or adhering to
expansion valve orifice
