Lubricant Adjusting Procedure for Components
Replacement Except Compressor
=NJHA0160S0201After replacing any of the following major components, add the
correct amount of lubricant to the system.

Ð Small leak *2
*1: If compressor is replaced, addition of lubricant is included in the table.
*2: If refrigerant leak is small, no addition of lubricant is needed.
Lubricant Adjustment Procedure for Compressor
Replacement
NJHA0160S02021. Discharge refrigerant into the refrigerant recovery/recycling
equipment. Measure lubricant discharged into the recovery/
recycling equipment.
2. Drain the lubricant from the ªoldº (removed) compressor into a
graduated container and recover the amount of lubricant
drained.
3. Drain the lubricant from the ªnewº compressor into a separate,
clean container.
4. Measure an amount of new lubricant installed equal to amount
drained from ªoldº compressor. Add this lubricant to ªnewº com-
pressor through the suction port opening.
5. Measure an amount of new lubricant equal to the amount
recovered during discharging. Add this lubricant to ªnewº com-
pressor through the suction port opening.
6. If the liquid tank also needs to be replaced, add an additional
5m!(0.2 Imp fl oz) of lubricant at this time.
Do not add this 5 m!(0.2 Imp fl oz) of lubricant if only
replacing the compressor.

REMOVALNJHA0212+When removing center bolt, hold clutch disc with clutch disc
wrench.

+Remove the clutch disc using the clutch disc puller.
Insert the holder's three pins into the holes in the clutch disc.
Rotate the holder clockwise to hook it onto the plate. Then,
tighten the center bolt to remove the clutch disc.
After removing the clutch disc, remove the shims from either
the drive shaft or the clutch disc.
RHA138E
+Remove the snap ring using external snap ring pliers.
RHA139E
+Pulley removal
Position the center pulley puller on the end of the drive shaft,
and remove the pulley assembly using any commercially avail-
able pulley puller.
To prevent the pulley groove from being deformed, the
puller claws should be positioned onto the edge of the
pulley assembly.

INSPECTIONNJHA0213Clutch DiscNJHA0213S01If the contact surface shows signs of damage due to excessive
heat, replace clutch disc and pulley.
PulleyNJHA0213S02Check the appearance of the pulley assembly. If the contact sur-
face of pulley shows signs of excessive grooving, replace clutch
disc and pulley. The contact surfaces of the pulley assembly should
be cleaned with a suitable solvent before reinstallation.
CoilNJHA0213S03Check coil for loose connection or cracked insulation.
RHA142E
INSTALLATIONNJHA0214+Install the field coil.
Be sure to align the coil's pin with the hole in the com-
pressor's front head.
+Install the field coil harness clip using a screwdriver.

+Install the pulley assembly using the installer and a hand
press, and then install the snap ring using snap ring pliers.
RHA127F
+Install the clutch disc on the drive shaft, together with the
original shim(s). Press the clutch disc down by hand.
RHA086E
+Using the holder to prevent clutch disc rotation, tighten the bolt
to 14 N´m (1.4 kg-m, 10 ft-lb) torque.
After tightening the bolt, check that the pulley rotates
smoothly.
RHA087E
+Check clearance around the entire periphery of clutch disc.
Disc-to-pulley clearance:
0.3 - 0.6 mm (0.012 - 0.024 in)
If the specified clearance is not obtained, replace adjusting
spacer and readjust.
Break-in OperationNJHA0214S01When replacing compressor clutch assembly, always carry out the
break-in operation. This is done by engaging and disengaging the
clutch about thirty times. Break-in operation raises the level of
transmitted torque.
