Removal Procedure for the Flexible Exhaust Pipe as an Assembly
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. All the components must be assembled in the same alignment as prior to disassembly. The components that require correct lateral alignment are shown at Positions (A, B, and C).

Follow Steps 2.a through Step 2.d in order to remove the flexible exhaust as an assembly from the Clean Emission Module (CEM) and the turbocharger.
Use suitable material in order to encase flexible exhaust pipe (3). Encasing the flexible exhaust pipe will prevent damage of the bellows. Encase bellows for the flexible exhaust pipe (3) between Position (D) and Position (E). Use cable straps in order to retain the suitable material. Note: Ensure that the flexible exhaust pipe is supported at all times.
Loosen ball clamp (2) from the flexible exhaust pipe assembly.
Loosen the bolt for V-band clamp (4). Note: If V-band clamp (4) remain tight on the flanges, apply releasing fluid on the V-band clamp. Lightly tap the bolt on the V-band clamp with a soft faced hammer in order to assist removal. Do not use a prybar in order to remove V-band clamp.
Remove the assembly of the flexible exhaust pipe from the CEM (1) and the turbocharger (5). Note: Ensure that the assembly of the flexible exhaust pipe is supported as the clamps are removed.Disassembly Procedure for the Flexible Exhaust Pipe Assembly
If any part of the flexible exhaust pipe assembly is damaged. Refer to Special Instruction, REHS5014, "Reuse Guideline for the Flexible Exhaust Pipe Group on Tier 4 Engines" for more information.

If necessary, follow Step 2.a through Step 2.d in order to disassemble the flexible exhaust pipe assembly.
Make temporary marks in Position (F) on all components of bellows (3) and tube assembly (6) in order to show correct orientation and alignment. Note: Do not scribe the components in order to mark the position of the flexible exhaust pipe assembly.
Loosen clamp (7) and remove tube assembly (6) from bellows (3).
Loosen ball clamp (8) and remove the ball clamp.
Remove bellows (3) from elbow (9). Note: Ensure that the flexible exhaust pipe bellows are not subjected to any undue stress.Assembly Procedure for the Flexible Exhaust Pipe Assembly
