This article describes the Perkins 2806F engine disassembly procedure for flexible exhaust pipes
CAUTION:
The ends of the bellows are very sharp. Injury could occur if the bellows are not handled properly Handle the bellows by the convolutions
NOTICE:
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 bel- lows. Misalignment can be identified by visually in- specting 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.
Typical example:
1. The lateral alignment of the bellows is critical. All the components must be assembled in the same alignment as prior todisassembly. The components that require correct lateral alignment are shown at Position (A) and Position (B).

a. Use suitable material to encase flexible exhaust pipe (3). Encasing the flexible exhaust pipe will prevent damage of the bellows. Encase bellows for the flexible exhaust pipe between Position
(C) and Position (D). Use cablestraps to retain the suitable material.
Note: Ensure that the flexible exhaust pipe is
supported at all times.
b. Loosen ball clamp (1) from the flexible exhaust pipe assembly.
c. Loosen ball clamp (5).
d. Remove the assembly of the flexible exhaust pipe from CEM (2) and elbow connection (4).
Note: Ensure that the assembly of the flexible
exhaust pipe is supported as the ball clamps are removed.
Disassembly Procedure for the Flexible Exhaust Pipe Assembly
1. Ensure that all components of the flexible exhaust pipe assembly are clean and free from wear and damage. If necessary, replace any components of the flexible exhaust pipe assembly that are worn or damaged. Refer to your Perkins distributor for further information.

2. Follow Steps 2.a through Step 2.d to remove the flexible exhaust as an assembly from Clean
Emission Module (CEM) (2) and elbow connection (4) on the turbocharger.

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