- Install the compressor into the J 34992
.
- Install the shaft key (4) into the key groove of the clutch plate and
hub (1).
| • | Allow the key to project 3.2 mm (0.126 in) out of
the key groove. |
| • | The shaft key is curved slightly in order to provide an interference
fit in the key groove of the hub. |
- Clean the frictional surfaces of the clutch plate and hub and
the clutch pulley rotor (2).
- Align the shaft key with the shaft keyway (3).
Notice: Do not drive or pound on the clutch hub or the shaft. Internal damage
to the compressor may result.
- Place the clutch plate and hub assembly onto the compressor
shaft.
- Remove the center screw from the J 33013-B
.
- Reverse the body direction of the center screw of the J 33013-B
.
- Install the J 33013-B
with the bearing.
- Back off the body of the J 33013-B
in order to allow the center screw to be threaded onto the
end of the compressor shaft.
- Hold the center screw of the J 33013-B
with a wrench.
Notice: If the center screw is threaded fully onto the end of the
compressor shaft, or if the body of the installer is held and the center screw
is rotated, the key will wedge and will break the clutch hub.
- Tighten the hex portion of the body of the J 33013-B
in order to press the hub onto the
shaft.
- Tighten the body of the J 33013-B
several turns.
- Remove the J 33013-B
.
- Verify that the shaft key remains in the keyway before installing
the clutch plate and hub assembly to the final position.
- Ensure that the gap between the frictional surfaces of the clutch
plate and the clutch rotor is within 0.40-0.50 mm (0.016-0.020 in).
- Remove the J 33013-B
.
- Verify that the shaft key is even with or slightly above the clutch
hub.
- Install the shaft nut.
- Hold the clutch plate and hub assembly with the J 33027-A
.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Tighten the shaft nut against the crankshaft shoulder, using a 17.5 N·m
(12.5 lb ft) torque wrench and the J 33022
.
Tighten
Tighten the nut to 16.5 N·m (12 lb ft).
- Spin the pulley rotor by hand in order to verify that the rotor
does not rub the clutch drive plate.
