Assembly Procedure

Tools Required

    â€¢ J 41048 Swage Clamp Tool
    â€¢ J 35566 Large Seal Retaining Clamp Tool

    Object Number: 386688  Size: SH
  1. Slide the new small swage clamp (2) and the boot (1) to the proper position (3) on the halfshaft bar.

  2. Object Number: 221917  Size: SH
  3. Install the new swage clamp onto the neck of the boot. Do not swage.
  4. Position the neck of the boot in the boot groove on the halfshaft bar.
  5. In order to swage the swage clamp, position the inboard end (1) of the halfshaft assembly in J 41048 .

  6. Object Number: 221918  Size: SH
  7. Align the swage clamp (2) within J 41048 .

  8. Object Number: 221917  Size: SH
  9. Place the top half of the J 41048 on the bottom half.
  10. Check to make sure there are no pinch points on the boot before proceeding.
  11. Insert the bolts (2).
  12. Tighten the bolts (2) by hand until snug.
  13. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  14. Align the following items:
  15. • The boot
    • The housing
    • The swage clamp

    Tighten
    Each bolt 180 degrees at a time, using a ratchet wrench. Alternate between each bolt until both sides are bottomed.

  16. Loosen the bolts.
  17. Separate the dies.
  18. Important: If deformities exist in the swage clamp, place the swage clamp back into J 41048 . Ensure the swage clamp covers the whole swaging area. Re-swage the swage clamp.

  19. Check the swage clamp for any "lip" deformities.

  20. Object Number: 340715  Size: SH

    Important: Assemble the joint with the convolute retainer in the correct position. Assemble the joint to meet the specified dimension to avoid boot damage.

  21. Install the convolute retainer over the boot capturing four convolutions.

  22. Object Number: 340719  Size: SH
