V5-Conventional Mount
REMOVAL PROCEDURETOOLS REQUIRED
^ J 39400-A Electronic Halogen Leak Detector
^ J 5403 Snap Ring Pliers
^ J 23128-A Seal Seat Installer And Remover
^ J 39400-A Electronic Halogen Leak Detector
^ J 39500-B A/C Refrigerant Recovery, Recycling and Recharging (ACR4) System
IMPORTANT: Do not change a shaft seal because of small amounts of oil found on an adjacent surface. The seal allows some oil to pass for lubrication purposes. Change the shaft seal when the following conditions exist:
^ A large amount of sprayed oil is found.
^ Actual refrigerant leak is found, using a J 39400-A or equivalent.
1. Recover the refrigerant using the J 39500-B.
2. Loosen the compressor in the mounting brackets. Reposition the compressor.
3. Remove the clutch plate and hub assembly.
4. Remove the shaft seal retaining ring using the J 5403.
5. In order to prevent dint or foreign material from damaging the compressor, thoroughly clean the following parts:
^ The inside of the compressor neck area surrounding the shaft
^ The exposed portion of the seal
^ The compressor shaft
^ The O-ring groove
IMPORTANT: Securely hand-tighten the handle of the J 23128-A. Do not use a wrench or pliers.
6. Fully engage the knurled tangs of the J 23128-A into the recessed portion of the seal by turning the handle clockwise.
7. Remove the seal from the compressor using a rotary-pulling motion. Discard the seal.
8. Remove the seal O-ring from the compressor neck using the J 9553-01. Discard the seal O-ring.
9. Inspect the shaft and the inside of the compressor neck again for dirt and foreign material.
10. Ensure that the shaft and the inside of the compressor neck are perfectly clean prior to installing new parts.
INSTALLATION PROCEDURE
TOOLS REQUIRED
^ J 5403 Snap Ring Pliers
^ J 23128-A Seal Seat Installer And Remover
^ J 33011 O-ring Installer
^ J 34614 Shaft Seal Protector
^ J 39500-B A/C Refrigerant Recovery, Recycling And Recharging System.
^ J 39893 Pressure Testing Connector
NOTE: Seals should not be re-used. Always use a new specification service seal kit. Be sure that the seal to be installed is not scratched or damaged in any way. Make sure that the seal is free of lint and dirt that could damage the seal surface or prevent sealing.
1. Thoroughly clean the seal O-ring groove in the front head.
2. Dip the new seal O-ring in clean 525 Viscosity refrigerant oil.
NOTE: Any attempt to use makeshift or inadequate service tools or equipment may result in damage and/or improper compressor operation.
3. Assemble the O-ring onto the J 33011.
4. Install the O-ring.
4.1. Insert the J 33011 into the compressor neck until the installer bottoms out.
IMPORTANT: The top groove in the compressor neck is for the shaft seal retainer ring.
4.2. Lower the moveable slide of the J 33011 in order to release the O-ring into the seal O-ring lower grove.
4.3. Rotate the J 33011 in order to seat the O-ring.
4.4. Remove the installer.
5. Dip the new shaft seal in clean 525 Viscosity refrigerant oil.
6. Assemble the seal to the J 23128-A by turning the handle clockwise.
6.1. Ensure that the stamped steel case side of the lip seal engages with the knurled tangs of the J 23128-A.
6.2. Ensure that the flared-out side of the lip seal faces toward the compressor.
NOTE: Use care when handling the seal protector. Do not nick the seal protector. This may damage the seal during installation. Ensure that the bottom of the seal protector is not flared. This may damage the seal during installation.
7. Install the J 34614 on the lip seal.
8. Install the lip seal onto the shaft.
8.1. Place the J 34614 over the end of the compressor shaft.
8.2. Slide the new seal onto the shaft using a rotary motion of the J 23128-A.
8.3. Ensure that the seal makes good contact with the O-ring.
Do not dislodge the O-ring.
8.4. Disengage the J 23128-A from the seal.
8.5. Remove the J 23128-A and the J 34614 from the compressor.
9. Use the J 5403 in order to install the new seal retainer ring with the flat side against the seal.
10. Use the sleeve of the J 33011 in order to press in the seal retainer ring. Ensure that the ring snaps into the groove.
11. Leak test the compressor.
11.1. Install the J 39893 on the rear head of the compressor.
11.2. Connect the gage charging lines using the J 39500-B.
11.3. Pressurize the suction and the high-side of the compressor using R-134a Refrigerant.
11.4. Temporarily install the shaft nut.
11.5. With the compressor in a horizontal position, rotate by hand the compressor shaft several turns in the operating direction.
11.6. Leak test the seal area. Correct any leaks found.
11.7. Recover the refrigerant.
11.8. Remove the shaft nut.
12. Remove any excess oil from the shaft and the inside of the compressor neck.
13. Install the clutch plate and hub assembly.
14. Install the compressor and the compressor belt. Tighten the bracket.
15. Evacuate and charge the refrigerant system using the J 39500-B.
