REFRIGERANT OIL
Page 37 of 1501
Only NEW, moisture-free refrigerant oil should be used in the
air conditioning system. This oil is highly refined and dehydrated so
moisture content is less than 10 parts per million. The oil container
must be tightly closed at all times when not in use, or moisture from
the air will be absorbed into the refrigerant oil.
SERVICING PRECAUTIONS
DISCHARGING SYSTEM
Discharge A/C system, using approved refrigerant
recovery/recycling equipment that meets SAE J2210 requirements. Always
follow recovery/recycling equipment manufacturer's instructions. After
refrigerant recovery process is completed, replace any refrigerant oil
removed with the same amount of NEW refrigerant oil.
DISCONNECTING LINES & FITTINGS
After system is discharged, carefully clean area around all
fittings to be opened. Always use 2 wrenches when tightening or
loosening fittings. Some refrigerant lines are connected with a
coupling. Special tools may be required to disconnect lines. Cap or
plug all openings as soon as lines are removed. DO NOT remove shipping
caps from replacement components until ready to install.
CONNECTING LINES & FITTINGS
NOTE: Ensure all replacement component connections match
connections of system being worked on.
Always use a NEW gasket or "O" ring when connecting lines or
fittings. Coat "O" ring with NEW refrigerant oil and ensure it is not
twisted during installation. Always use two wrenches to prevent damage
to lines and fittings.
PLACING SYSTEM IN OPERATION
After component service or replacement has been completed and
all connections have been made, thoroughly evacuate system with a
vacuum pump. Charge system with proper amount of refrigerant and
perform leak test. See REFRIGERANT OIL & REFRIGERANT SPECIFICATIONS
table for system capacities. Ensure there are no leaks at any fitting
that has been opened. After system has been leak tested, check system
performance.
NIPPONDENSO 10-CYL.

Replacement compressor is shipped with NEW refrigerant oil.
Drain, measure and discard refrigerant oil from old compressor. Drain
NEW refrigerant oil from replacement compressor equal to difference
between amount drained from old compressor and amount shipped in
replacement compressor. If any other components are replaced, add NEW
refrigerant oil as specified. See COMPONENT REFRIGERANT OIL CAPACITIES
(MITSUBISHI - NIPPONDENSO 10-CYL.) table.

Removal
1) Hold clutch plate stationary. Remove clutch plate center
bolt and clutch plate. If clutch plate cannot be removed by hand,
tighten an 8-mm or 10-mm bolt into clutch plate center bolt hole to
remove clutch plate.
2) Remove shim(s) and pulley snap ring from compressor shaft\
.
Tap pulley using a plastic hammer and remove pulley from compressor
shaft. See Fig. 1 or 2. Remove retaining screw for clutch coil lead.
Remove clutch coil snap ring and clutch coil.
Installation
1) To install, reverse removal procedure. Ensure clutch coil
pin is aligned with hole in compressor housing. Ensure clutch coil
lead is positioned properly. Ensure NEW snap rings are installed with
beveled side facing out. Tighten shaft bolt to 10-13 ft. lbs. (14-17
N.m).
2) Check air gap between clutch plate and pulley. Position
dial indicator on clutch plate. Energize clutch coil and zero dial
indicator. De-energize clutch coil and measure air gap (clutch plate
movement). Ensure air gap between clutch plate and pulley is 0.014-0.
026" (0.35-0.65 mm). If air gap is incorrect, add or remove shim(s) \
as
necessary. Ensure pulley rotates freely.
NOTE: On some compressors, it is necessary to use a dial indicator
on clutch plate to check air gap. Energize clutch coil and
zero dial indicator. De-energize clutch coil and measure air
gap. Ensure air gap is as specified.

SHAFT SEAL
CAUTION: Secure rear housing to compressor body using a vise before
removing front housing through-bolts. Compressor rear housing
may separate from compressor body, spilling refrigerant oil.
Removal
1) Remove clutch coil. See CLUTCH COIL. See Fig. 1 or 2.
Position compressor in a vise so compressor rear housing is secured to
compressor body. Remove front housing through-bolts and front housing.
2) Using a flat-blade screwdriver, remove felt retainer and
felt from front housing. Remove shaft seal snap ring. Using a flat-
blade screwdriver, remove shaft seal and "O" ring. See Fig. 1 or 2.
Installation
1) Inspect compressor shaft and front housing bore for damage
and/or excessive wear. Ensure "O" ring and shaft seal seat are clean.
Apply NEW refrigerant oil to compressor side of front housing bore.
Lubricate "O" ring and shaft seal with NEW refrigerant oil. Using a
21-mm socket, install shaft seal with "O" ring side facing away from
compressor. Install shaft seal snap ring. See Fig. 1 or 2.
2) Install felt into felt retainer. Using a 14-mm deep
socket, install felt and felt retainer. Lubricate compressor shaft.
Install front housing using care not damage shaft seal lip. See Fig. 1
or 2.
3) Alternately tighten front housing through-bolts to 19 ft.
lbs. (26 N.m). Install clutch plate center bolt. Using an INCH-lb.
torque wrench, ensure compressor breakaway torque is 43 INCH lbs. (4.9
N.m) or less. To complete installation, reverse removal procedures.
Ensure air gap between clutch plate and pulley is correct. See
CLUTCH COIL .
