Usage:

MH3037 JPB

Removal Procedure

------ WARNING! ------

Hot oil and components can cause personal injury.

Do not allow hot oil or components to contact the skin.

Be sure that the engine and components are cool enough to touch with your bare hand prior to performing any service work.


------ 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 when not installed in the application. Failure to support the bellows adequately could result in the failure of the bellows. Do not use power tools 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.


  1. Open right engine hood.
