^ Lower the movable slide of J 33011 into the lower groove.
^ Rotate J 33011 to seat the seal (15).
^ Remove J 33011.

2. Seal seat (14).
^ Coat the seal (14) with clean 525 viscosity refrigerant oil.
^ Mount the seal (14) to J 9392-01 by engaging the tabs of the seal with the tangs of J 9392-01.
^ Place J 22974 over the end of the compressor shaft (39).
^ Slide the seal (14) and J 22974 down onto the compressor shaft (38).
^ Twist J 9392-01 to the right (clockwise) while pushing the seal assembly down the shaft (38) until the seal assembly (14) engages the flats on the shaft and seat in place.
^ Disengage J 9392-01 by pressing downward and twisting to the left (counterclockwise).

3. Ceramic seat seat (13).
^ Seal (13) to J 23128.
^ Dip the seal (13) into clean 525 viscosity refrigerant oil.
^ Install J 23128 and the seal (13) over the compressor shaft (39).
^ Push the seal (13) info place with a rotary motion.

Important
^ Do not dislodge the seal (O-ring) (15).

4. Seal shaft retainer ring (12) with J 5403.
^ Place the flat side against the seal seat.
^ Use the sleeve of J 9393-B to press the ring into its groove.

5. J 9625 to the rear head of the compressor:
^ Gage charging lines or pressurize the suction side (low pressure side) of the compressor with refrigerant to equalize the pressure to the drum pressure.

6. Shaft nut (1) with J 9399.
^ Place the compressor in a horizontal position with the oil sump down.
^ Rotate the compressor shaft by hand.
^ Leak test with J 23400.
^ Replace shaft nut (1) with a new one.

7. New absorbent sleeve (11).
^ Roll the material into a cylinder, overlapping the ends.
^ Slip the sleeve into the compressor neck with the overlap toward the top of the compressor
^ With a screwdriver spread the sleeve ends of the sleeve butt at the top vertical centerline.

Shaft And Seal Position And Correct Position Gaging Guide:

8. Sleeve retainer (10) with J 9393.
^ Place the flange face against the front end of the sleeve.
^ Press and tap with a mallet to set the retainer and sleeve into place. Place the retainer 0.7937 mm (0.03125-inch) from the face of the compressor neck.

9. Clutch plate and hub assembly (2).

Important
^ Using improper procedures. pounding or collisions can damage the shaft seal and the axial plate. If the axial plate is out of position. the carbon face of the shaft seal may not contact the seal seat.
^ To check the position of the axial plate on the shaft. remove the clutch driven plate and measure the distance between the front head extension and the flat shoulder on the shaft with a wire gage. The clearance should be 0.66-1.9 mm (0.026-0.075-inch).
^ If the shaft has been pushed back in the axial plate (measurement greater than 1.9 mm (0.075-inch), disassemble the compressor and replace the shaft and axial plate assembly. thrust races and thrust bearings.
^ If there is too much or not enough air gap between the drive and driven plates. check for shaft dislocation. It will not be possible to service the compressor if the carbon seat is not seating against the seal seat.
