and moisture to a minimum.
CONNECTING LINES AND FITTINGS
A new gasket or "O" ring should be used in all instances when
connecting lines or fittings. Dip "O" ring in new refrigerant oil and
ensure it is not twisted during installation. Always use 2 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, evacuate system thoroughly with a
vacuum pump. Charge system with proper amount of refrigerant and
perform a leak test. See REFRIGERANT OIL & R-12 SPECIFICATIONS chart
in this section for system capacities. Be sure to check all fittings
that have been opened. After system has been leak tested, make a
system performance check.
NOTE: Air conditioning systems will not normally need addition of
refrigerant oil unless definite oil loss has occurred due to
ruptured lines, leaking compressor seals, compressor
overhaul or component replacement.
ATSUGI ROTARY VANE DRAIN & REFILL
1) Before checking and adjusting oil level, operate
compressor at engine idling speed, with controls set for maximum
cooling and high blower speed, for 20 to 30 minutes to return oil to
compressor.
2) Stop engine, discharge refrigerant and remove compressor
from vehicle. See SERVICING PRECAUTIONS at beginning of article. Drain
compressor oil from compressor discharge port and measure the amount.
Oil is sometimes hard to drain when compressor is cool. Remove oil
while compressor is warm.
3) If the amount drained is less than 3 ounces, conduct leak
tests at system connections, and if necessary, repair or replace
faulty parts. Check purity of oil and adjust oil level as follows.
4) If amount drained was above 3 ounces, oil level is right.
Pour in same amount as was drained. If amount drained was below 3
ounces, pour in 3 ounces of new refrigerant oil.
BOSCH 6-CYL DRAIN & REFILL
1) Before checking and adjusting oil level, operate
compressor at engine idling speed, with controls set for maximum
cooling and high blower speed, for 20 to 30 minutes to return oil to
compressor.
2) Stop engine and discharge refrigerant. Remove refrigerant
oil level inspection plug on side of compressor. Oil should be at
lower lip of threaded hole. Add necessary new refrigerant oil (if
low). Replace inspection plug and tighten to 10-12 ft. lbs. (14-16 N.
m).
CALSONIC V5 5-CYLINDER
1) Before checking and adjusting oil level, operate
compressor at 1000-1500 engine RPM, and set controls at maximum
cooling and blowing speed for 20-30 minutes to return oil to
immediately before connections are made. This will keep entry of air
and moisture to a minimum.

ATSUGI ROTARY VANE CLUTCH R & I
Removal
When replacing compressor clutch, be careful not to scratch
shaft or bend pulley. When removing center bolt, hold clutch disc with
Clutch Holder (KV99231010). Using Hub Puller (KV998VR001 &
KV99231010), remove clutch disc. When removing pulley, remove lock nut
with Hub Socket (KV99235160).
Installation
Wipe oil off clutch surface. Adjust disc pulley clearance to
.012-.024" (.3-.6 mm). Tighten center bolt to 80-104 INCH lbs. (9.1-
11.8 N.m). Tighten clutch lock nut to 22-29 ft. lbs. (29-39 N.m). See\

ring and carbon seal contact surface of shaft seal seat for damage.
Make sure that "O" ring contact surface on front cover is not damaged.
Make sure refrigerant oil is applied to oil seal in shaft seal seat.
Installation
1) To install, reverse removal procedure. Ensure shaft seal
contact surface is free of dirt. Lubricate with refrigerant oil. Cap
end of compressor shaft.
2) Using Guard (KV994C1143), insert shaft seal. Be sure shaf\
t
seal case is aligned with shaft. Apply force to turn seal to left and
right. Ensure shaft seal seats properly in shaft cut-out.
3) Fit "O" ring to outside groove of shaft seal seat. Ensure
"O" ring seats properly. Apply refrigerant oil on contact surfaces and
around shaft seal seat. Lightly coat surface of shaft with refrigerant
oil.
4) Install key on compressor shaft. Using snap ring pliers,
compress retainer ring and fit retainer ring into front cover. Seat
retainer ring firmly in groove. Thoroughly wipe grease or oil from
shaft surface.
5) Connect Installer (KV99412329) to shaft of compressor, an\
d
turn shaft 5 or 6 times in a clockwise direction to seat seal. See
REFRIGERANT OIL & R-12 SPECIFICATIONS chart in this section for system
capacities.
MATSUSHITA ROTARY VANE CLUTCH R & I
Removal & Installation
1) Insert two 5 mm bolts into threaded holes in armature.
Using a screwdriver as lever in between bolts, remove center bolt.
remove armature and shim from shaft.
2) Remove snap ring. Using a puller, remove pulley.
Disconnect electrical leads from field coil. Remove 3 field coil
mounting bolts. Remove field coil. See Fig. 12. To install, reverse
removal procedure.
