Typical example
Use the correct personal protective equipment when removing the clamp.
Note: Do not center punch the spot weld on clamp (2).
If you need to reinstall original bellows (1), place the internal area in Position (G) (not shown) of bellows (1) on a suitable support. Use Tooling (A) to drill a pilot hole through the spot weld in Position (H) on clamp (2).
Use Tooling (B) to drill out the spot weld in Position (H) on clamp (2). Remove clamp (2) from bellows (1).
Remove all burrs from the internal and external areas of clamp (2). Ensure that debris does not enter bellows (1).

Illustration 6 g06040223Note: Make sure that bellows (1) is not subjected to any undue stress.Note: If you install a new bellows (1), clamp (2) will be pre-installed to bellows (1).
Position a new clamp (2) onto bellows (1). Hand tighten new clamp (2). Make sure that the center of new clamp (2) is central to Slots (J) on bellows (1). New clamp (2) must be flush with the end of bellows (1).Note: Ensure that the bellows are not subjected to any undue stress.
Position a new ball clamp (8) onto adapter (7).
Position bellows (1) onto adapter (7)Note: Ensure that the bellows are not subjected to any undue stress.
Tighten ball clamp (8) hand tight.Installation Procedure for the Flexible Exhaust Pipe as an Assembly
Inspect the bellows for damage prior to installation. If there is any damage to the convolutions, discard the bellows. If there is any difficulty in installation after the repair, discard the bellows.
Check the flexible exhaust pipe assembly for damage. Refer to Special Instruction, REHS5014, "Reuse Guideline for the Flexible Exhaust Pipe Group on Tier 4 Engines" for more information.
Failure to reinstall the bellows into the original position will result in a failure of the bellows and possible emissions failure.
