REPLACEMENT
1. DISCHARGE REFRIGERANT FROM
REFRIGERATION SYSTEM
SST 07110-58060 (07117-58080, 07117-58090,
07117-78050, 07117-88060, 07117-88070,
07117-88080)
(a) Turn the A/C switch to ON.
(b) Operating the cooler compressor at the engine rpm
of approx. 1,000 for 5 to 6 minutes, circulate the
refrigerant and collect the compressor oil remaining
in each component into the cooler compressor as
much as possible.
(c) Stop the engine.
(d) Let the refrigerant gas out.

07117-88060, 07117-88070, 07117-88080)
2. CHARGE REFRIGERANT
(a) Using a vacuum pump, perform a vacuum purging.
(b) Charge refrigerant, HFC-134a (R134a).
Standard:
780 +- 30 g (27.5 +- 1.06 oz.)
SST 07110-58060 (07117-58060, 07117-58070,

07117-88060, 07117-88070, 07117-88080)
3. WARM UP ENGINE
4. INSPECT REFRIGERANT LEAK
(a) Using a gas leak detector, check for leakage of the
refrigerant.

2. INSPECT COMPRESSOR OIL
(a) When replacing the compressor and magnetic
clutch with a new one, after gradually removing the
refrigerant gas from the service valve, drain the
following amount of oil from the new compressor
and magnetic clutch before installation.
Standard:
(Oil capacity inside new compressor and
magnetic clutch:
225 + 15 cc (7.6 + 0.5 fl.oz.)) - (Remaining oil
amount in the removed compressor and
magnetic clutch) = (Oil amount to be
removed when replacing)
NOTICE:
• When checking the compressor oil level,
observe the precautions on the cooler
removal / installation.
• Because compressor oil remains in the pipes
of the vehicle, if a new compressor and
magnetic clutch is installed without removing
some oil inside, the oil amount becomes
excessive, preventing heat exchange in the
refrigerant cycle and causing refrigerant
failure.
• If the remaining oil in the removed
compressor and magnetic clutch is too small
in volume, check for oil leakage.
• Be sure to use ND-OIL 8 for compressor oil.
3. INSPECT COMPRESSOR AND MAGNETIC CLUTCH
(a) Disconnect the connector from the compressor and
magnetic clutch.

(d) Using a snap ring expander, install the magnetic
clutch rotor and a new snap ring with the chamfered
side facing up.
NOTICE:
• Do not expand the snap ring by more than
35.5 mm (1.39 in.) when installing it.
• Do not damage the seal cover of the bearing
when installing the snap ring.
(e) Install the magnet clutch washer and the magnet
clutch hub.
NOTICE:
Do not change the combination of the magnetic
clutch washers used before disassembly.
(f) Using vise pliers, hold the magnetic clutch hub and
install the bolt.
Torque: 18 N*m (183 kgf*cm, 13 ft.*lbf)
NOTICE:
Make sure that there is no foreign matter or oil
on the compressor shaft, bolt, and clutch hub.

(b) Apply sufficient compressor oil to a new O-ring and
the fitting surface of the compressor and magnetic
clutch.
Compressor oil:
ND-OIL 8 or equivalent
(c) Install the O-ring onto the suction hose sub-
assembly.
