6.Remove the inner and outer O - ring (A).
When assembling, use a new gasket and O - ring.
Page 627 of 1575
7.Mount the pump in a vise and remove the pulley (A) nut and the spring washer.
8.After removing the snap ring (A) of the shaft with snap ring pliers, remove the dust spacer.
9.Tap the rotor side of the shaft slightly with a plastic hammer (A) to remove the shaft (B).
10. Remove the oil seal from the oil pump body.
When assembling, use a new oil seal.
11. Remove the connector from the oil pump body, and take out the flow control valve (A) and the flow control spring
(B).
Page 628 of 1575
12.Remove the O - ring from the connector.
Do not disassemble the flow control valve.
INSPECTION
1.Check that the flow control valve is not bent.
2. Check the shaft for wear and damage.
3. Check the V belt for wear and deterioration.
4. Check the grooves of the rotor and vanes for stratified abrasion.
5. Check the contact surface of the cam ring and vanes for stratified abrasion.
6. Check vanes for damage.
7. Check that there is no striped wear in the side plate or contacting part between the shaft and the pump cover
surface.
REASSEMBLY
1.Install the flow control spring (B), the flow control valve (A) and the connector into the pump body.
2.Install the oil seal in the pump body by using the special tool (09222- 32100).
Page 630 of 1575
6.Install the oil pump side plate (A).
7.After inserting the lock pin into the groove of the front housing, install the camring (A) attending to the direction.
8.Install the rotor and the vanes.
9.Install the gasket and oil pump cover assembly (A).

INSTRUCTIONS
WHEN HANDLING REFRIGERANT
1. R- 134a liquid refrigerant is highly volatile. A drop on the skin of your hand could result in localized frostbite. When
handling the refrigerant, be sure to wear gloves.
2. It is standard practice to wear goggles or glasses to protect your eyes, and gloves to protect your hands. If the
refrigerant splashes into your eyes, wash them with clean water immediately.
3. The R- 134a container is highly pressurized. Never leave it in a hot place, and check that the storage temperature
is below 52°C (126°F)
4. An electronic leak detector should be used to check the system for refrigerant leakage. Bear in mind that the R-
134a, upon coming into contact with flame, produces phosgene, a highly toxic gas.
5. Use only recommended the lubricant for R- 134a systems. If lubricants other than the recommended one used,
system failure may occur.
6. PAG lubricant absorbs moisture from the atmosphere at a rapid rate, therefore the following precautions must be
observed:
a. When removing refrigerant components from a vehicle, cap immediately the components to prevent from the
entry of moisture.
b. When installing refrigerant components to a vehicle, do not remove the cap until just before connecting the
components.
c. Complete the connection of all refrigerant tubes and hoses without delay to prevent the A/C system from taking
on moisture.
d. Use the recommended lubricant from a sealed container only.
7. If an accidental discharge in the system occurs, ventilate the work area before resuming service.
WHEN REPLACING PARTS ON A/C SYSTEM
1.Never open or loosen a connection before discharging the system.
2. Seal the open fittings of components with a cap or plug immediately to prevent intrusion of moisture or dust.
3. Do not remove the sealing caps from a replacement component until it is ready to be installed.
4. Before connecting an open fitting, always install a new sealing ring. Coat the fitting and seal with refrigerant oil
before making the connection.
WHEN INSTALLING CONNECTING PARTS
FLANGE WITH GUIDE PIN
