Compressor Oil
1. Remove the drain plug and the oil filler plug, then
drain out the oil.
2. Measure the drained oil with a measuring cylinder.
3. Check the drained oil for any of the following con-
ditions:
a) Whether the opacity of the oil has increased.
b) Whether the oil color has changed to red.
c) Whether foreign matter, such as metal filings,
etc., is present in the oil.
Note:
If the oil drained from the compressor is as
described above, replaced it with new oil.

Installation of Front Cylinder Head
1. Place the cylinder shaft assembly with the front side
upward.
2. Install the front suction valve so that it matches the
spring pin.
Note:
Check that the valve tallies with the valve es-
cape groove of each cylinder.
3. Install the front valve plate on the front suction
valve.
4. Coat the new gasket with clean compressor oil and
install it on the front valve plate.
5. Install the front cylinder head.
In case difficulty is encountered in fitting, install the
cylinder head lightly with a plastic mallet.
Note:
When installing the front cylinder head, be
careful that you do not scratch the seat sur-
face of the seal seat fitted onto the front cyl-
inder head with the lip of the driveshaft.
Mount the new gasket on the through-bolts. Insert six
through-bolts from the front side and tighten them to
20—24 N m (2.0—2.4 m-kg, 14.5—17.3 ft-lb)
Each bolt should be equally tightened more than three
times to ensure the specified torque.
The bolts should be tightened in the order shown in
the figure.
Place felt on the front cylinder head.
Turn the driveshaft 2 or 3 times by hand, and make
sure that it rotates smoothly.

16 CONDENSER
CONDENSER
ON-VEHICLE INSPECTION
1. Check the condenser fins for blockage or damage.
If the fins are clogged, clean them with compressed air.
If the fins are bent, straighten them with a screwdriver or pair of pliers.
2. Check the condenser fittings for leakage.
Repair or replace, if necessary.
REMOVAL OF CONDENSER
1. Discharge the air conditioning system. (Refer to page 16—9.)
2. Remove the front grille and the air seal cover.
3. Disconnect the discharge flexible hose from the condenser inlet fitting.
4. Disconnect the liquid line pipe from the condenser outlet fitting.
Note:
Plug the open fittings immediately to keep moisture out of the system.
6. Remove the condenser.

INSTALLATION OF CONDENSER
1. Install the condenser by using the two bolts and two nuts.
2. Connect the liquid line pipe and the discharge flexible hose to the condenser.
Tightening torque:
Liquid line pipe: 15—25 Nm (1.5—2.5 m-kg, 11—18 ft-lb)
Discharge flexible hose: 15—22 N-m (1.5—2.2 m-kg, 11—16 ft-lb)
3. Install the front grille and the air seal cover.
4. If the condenser is replaced with a new one, supply compressor oil.
Compressor oil: 30 cc (1.83 cu in)
5. Evacuate, charge, and test the air conditioning system.

RECEIVER-DRIER 16
RECEIVER-DRIER
ON-VEHICLE INSPECTION
1. Use a leak detector to check the sight glass, the
fusible plug, and the fittings for leakage.
Repair or replace, if necessary.
2. Check the receiver-drier for clogging.
a) Run the engine at fast idle with the air conditioner
on.
b) Check both inlet and outlet temperatures.
If there is a great difference between the two tem-
peratures, replace the receiver-drier.

REMOVAL OF RECEIVER-DRIER
1. Discharge the air conditioning system.
(Refer to page 16—9)
2. Disconnect the two liquid line pipes from the
receiver-drier.
Note:
Plug the open fittings immediately to keep
moisture out of the system.
3. Remove the receiver-drier from the bracket.
INSTALLATION OF RECEIVER-DRIER
1. Install the receiver-drier onto the bracket.
Note:
Do not remove the blind plugs until ready for
connection.
2. Connect the two liquid line pipes to the
receiver-drier.
Tightening torque:
15—25 N m (1.5—2.5 m-kg, 11—18 ft-lb)
3.
If
the receiver-drier is replaced with a new one, add
compressor oil to the compressor.
Compressor oil: 10 cc (0.61 cu in)
