.
- Clamp the J 34992
in a vise.
- Use thumb screws in order to attach the compressor to the holding
fixture.
Notice: Do not drive or pound on the clutch hub or shaft. Internal damage to
the compressor may result. The forcing tip on the J 33013-B
remover/installer center screw must be flat or the end of the shaft/axial
plate assembly will be damaged.
- Ensure that the center screw forces the tip to thrust against the end
of the shaft.
- Thread the J 33013-B
into the hub.
- While holding the body of J 33013-B
of the remover with a wrench, turn the center screw into
the remover body in order to remove the clutch plate and hub assembly (1).
- Remove the shaft key. Retain the shaft key for reassembly.
Installation Procedure
- Install the shaft key (4) into the hub key groove.
Allow the key to project approximately 3.2 mm (0.125 in)
out of the keyway (3). The shaft key curves slightly in order to provide
an interference fit in the hub key groove.
- Clean the following components:
- Align the shaft key (4) with the shaft keyway (3).
- Place the clutch plate and the hub assembly (1) onto the
compressor shaft.
- Remove the forcing tip on the J 33013-B
.
- Reverse the body direction on the center screw.
- Install the J 33013-B
with the bearing.
- Back off the body of the J 33013-B
as necessary in order to permit the center screw to be threaded
onto the end of the compressor shaft.
- Hold the center screw with a wrench.
- Tighten the hex portion of the J 33013-B
body in order to press the hub onto the shaft.
- Tighten the body several turns.
- Remove the installer. Ensure that the shaft key remains in place
in the keyway.
- Install the clutch plate and hub assembly to the final position.
Ensure that the air gap (2) between frictional surfaces of the
clutch plate and clutch rotor measures within 0.50-0.76 mm (0.020-0.030 in).
- Remove the J 33013-B
.
- Verify proper positioning of the shaft key.
Ensure that the shaft key is even with or slightly above the clutch
hub.
