Fig. 10 Installing Pulley Rotor Bearing
Install or Connect
Place the pulley rotor on the J 2 1352-A support block to
fully support the rotor hub durinsi bearing installation
(Fig. 10).
NOTICE: DO NOT
support the rotor by resting the
pulley rim on a flat surface during the bearing
installation or the rotor face will be bent.
Align the new bearing squarely with the hub bore and
using puller and bearing installer J 9481-A with
universal handle J 29886, drive the bearing fully into the
hub (Fig. 10). The installer will apply force to the outer
race o f the bearing, if used as shown.
Place bearing staking guide J 33019-1 and bearing
staking pin J 3 3 0 1 9 -2 in the hub bore as shown in
Figure 11. Shift the rotor and bearing assem bly on the
J 2 1 3 5 2 -A support block to give full support of the hub
under the staking pin location. A h eavy-duty rubber
band m ay be used to hold the stake pin in the guide (Fig.
11), and the stake pin should be properly positioned in
the guide after each im pact on the pin.
U sing care to prevent personal injury, strike the staking
pin with a ham m er until a metal stake, sim ilar to the
original, is formed
down to
but
not touching
the
bearing.
N oisy bearing operation and reduced bearing life may
result if outer bearing race is deform ed while staking,
The stake metal should not contact the outer race of the
bearing. Stake three places 120 degrees apart as shown in
Figure 12.

5. With the com pressor m ounted to the J 33026 holding
fixture, position the rotor and bearing assem bly on the
front head (Fig. 13).
6. Position the J 3 3 0 17 pulley, rotor and bearing installer
and J 3 3 0 2 3 -A puller pilot directly over the inner race o f
the bearing (Fig. 13).
7. Position puller crossbar J 8 4 3 3 - 1 on the puller pilot
J 3 3 0 2 3 -A and assem ble the two J 33 0 2 6 -2 through bolts
and w ashers through the puller bar slots and thread them
into the J 33026 holding fixture (Fig. 13). The thread o f
the through bolts should engage the full thickness o f the
holding fixture.
8. Tighten the center screw in the J 8433-1 puller crossbar
to force the pulley rotor and bearing assem bly onto the
com pressor
front head (Fig. 13). Should the
J 33017 pulley rotor and bearing installer slip off direct
in-line contact with the inner race o f the bearing, loosen
the J 8433-1 center forcing screw and realign the
installer and pilot so that the J 33017 installer will
properly clear the front head.
9. Install rotor and bearing assem bly retainer ring, using
snap ring pliers J 6083 (Fig. 6).
10. Reinstall clutch plate and hub assem bly as described
previously.
