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.

1) Install pinion bearing races in carrier. For front race
use Handle (MB990938-01) and Race Installer (MB990934-01) for 2.4L a\
nd
2.6L models and Race Installer (MB990935-01) for 3.0L models. For rear\
race, use Handle and Race Installer (MB990936-01). Ensure races are
fully seated.
2) Install Pinion Height Gauge (MB990901-01) and pinion
bearings. See Fig. 4. DO NOT install oil seal. Using INCH lb. torque
wrench, measure pinion rotating torque. Gradually tighten pinion
height gauge to increase rotating torque to proper specification. See
PINION ROTATING TORQUE SPECIFICATIONS table.
3) Install Cylinder Gauge (MB990903-01) in side bearing
seats. Ensure flat areas are aligned and gauge contacts side bearing
seat firmly. See Fig. 4.
4) Select adjusting shim with same thickness as gap between
cylinder gauge and pinion height gauge. Use minimum amount of
adjusting shims. Install selected adjusting shims between drive pinion
gear and rear pinion bearing. Using Bearing Installer (MB990802-01),
install rear pinion bearing.

DRIVE PINION HEIGHT
1) Install pinion bearing races in carrier. Ensure races are
fully seated. Install pinion height gauge and pinion bearings. Use
Pinion Height Gauge (MB990901) for all others. See Fig. 10. DO NOT
install oil seal.
2) Using torque wrench, measure pinion rotating torque.
Gradually tighten pinion height gauge to increase rotating torque to
3.5-4.3 INCH lbs. (.40-.48 N.m).
3) Install cylinder gauge in side bearing seats. Ensure flat
areas are aligned and gauge contacts side bearing seat firmly. See
Fig. 11 . Select adjusting shim with same thickness as gap between

SIRENS

cylinder head design and type of metal used.
Remove valve guide from cylinder head by pressing or tapping
on a stepped drift. See Fig. 8. Once valve guide is installed,
distance from cylinder head to top of valve guide must be checked.
This distance must be within specification.
Aluminum heads are often heated before installing valve
guide. Guide is sometimes chilled in dry ice before installation.
Combination of a heated head and chilled guide insures a tight guide
fit upon assembly. The new guide must be reamed to specification.

VALVES & VALVE SEATS
Valve Grinding
Valve stem O.D. should be measured in several areas to
indicate amount of wear. Replace valve if not within specification.
Valve margin area should be measured to ensure that valve can be
grounded. See Fig. 9.
Fig. 9: Measuring Valve Head Margin - Typical
This Graphic For General Information Only
If valve margin is less than specification, this will burn
the valves. Valve must be replaced. Due to minimum margin dimensions
