CAP-BEARING 3602344 - Caterpillar

Removal Procedure
The ends of the bellows are very sharp. Injury could occur if the bellows are not handled properly. Handle the bellows by the convolutions.
The bellows must be supported at all times when the bellows are not installed in the application. Failure to support the bellows adequately could result in the failure of the bellows. Do not use power tools in order to disassemble or assemble any part of the flexible exhaust system.The alignment of the bellows is important. Incorrect alignment may lead to premature failure of the bellows. Misalignment can be identified by visually inspecting the uniformity of the spacing between the convolutions on the bellows.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.

The lateral alignment of the bellows is critical. Ensure that the alignment is maintained in Position (A) and Position (B).
Remove the nuts and bolts (3).
Remove gasket (2) (not shown) from between Clean Emission Module (CEM) (1) and flexible exhaust pipe (4).
Remove nuts (5) and bolts (7). Support flexible exhaust pipe (4) as the nut and bolts are removed.
Remove flexible exhaust pipe (4).
Remove gasket (6) (not shown) from the Aftertreatment Regeneration Device (ARD). Assembly Procedure
Ensure that the flexible exhaust pipe assembly is clean and free from wear and damage. If necessary, replace the flexible exhaust pipe assembly as an assembly.

The lateral alignment of the bellows is critical. Ensure that the alignment is maintained in Position (A) and Position (B).
Position a new gasket (6) (not shown) onto the Aftertreatment Regeneration Device (ARD).
Install flexible exhaust pipe (4). Ensure the correct orientation of the flexible exhaust pipe.
Install nuts (5) and bolts (7). Support flexible exhaust pipe (4) as the nut and bolts are installed.
Position a new gasket (2) (not shown) between Clean Emission Module (CEM) (1) and flexible exhaust pipe (4).
Install the nuts and bolts (3) hand tight.
Tighten nuts (5) and bolts (7) to a torque of 25 N m (221 lb in).
Tighten the nuts and bolts (3) to a torque of 25 N m (221 lb in).
Ensure that the alignment is maintained in Position (A) and Position (B) as the nuts and the bolt are tightened.
