Clutch Rotor and/or Bearing Install HT6/HD6/HU6

Tools Required

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.

1. Place the pulley rotor on the J 21352-A in order to fully support the rotor hub during bearing installation.
2. Use the following tools in order to align the new bearing squarely with the hub bore:

•	The J 41552

•	The J 9481-A

•	The J 29886

3. Drive the bearing fully into the hub.

The installer will apply force to the outer race of the bearing, if used as shown.




4. Place the J 33019 in the hub bore.
5. Shift the rotor and bearing assembly on the J 21352-A in order to fully support the hub under the staking pin location.

Use a heavy-duty rubber band (1) in order to hold the stake pin in the guide. Properly position the stake pin in the guide after each impact on the pin.

Caution: Use care in order to prevent personal injury when striking the staking pin with a hammer.

6. Strike the staking pin with a hammer until a metal stake, similar to the original, forms down to, but not touching, the bearing.




Important: Noisy bearing operation and reduced bearing life may result if the outer bearing race is deformed while staking. Ensure that the stake metal does not contact the outer race of the bearing.

7. Stake 3 locations on the bearing race 120 degrees apart as shown.



8. With the compressor mounted on the J 34992 , position the pulley rotor (1) and the bearing assembly on the front head.
9. Position the J 33017 and the J 33023-A directly over the inner race of the bearing.
10. Position the J 8433-1 on the J 33023-A .
11. Assemble the 2 through bolts and the washers through the puller bar slots.
12. Thread the through bolts into the J 34992 .

Ensure that the thread of the through bolts engage the full thickness of the J 34992 .

13. Tighten the center screw in the J 8433-1 in order to force the pulley rotor and bearing assembly onto the compressor front head.

If the J 33017 slips off direct in-line contact with the inner race of the bearing, perform the following steps:

13.1.

Loosen the J 8433-3 .

13.2.

Realign the installer and the pilot in order to ensure that the J 33017 properly clears the front head.




14. Use the J 6083 in order to install the following components:

•	The pulley rotor (1)

•	The retaining ring (2)

15. Install the clutch plate and hub assembly. Refer to Compressor Clutch Plate/Hub Assembly Replacement .
