Catalyst Module - Replace

Usage:

3512C NJT


NOTICE

Ensure that all components are free of contaminants before installing. Contaminants may cause premature wear and reduced component service life.



NOTICE

Ensure that all components have cooled before performing maintenance on the components.


Use a hoist to remove heavy components. All supporting members (chains and cables) should be parallel to each other. The chains and cables should be perpendicular to the top of the object that is being lifted.

Some removals require lifting fixtures in order to obtain proper balance and safety.

Use the lifting eyes that are on the catalyst module.

Lifting eyes are designed and installed for the specific component. Alterations to the lifting eyes make the lifting eyes and the lifting fixtures obsolete. If alterations are made, ensure that proper lifting devices are provided. Consult your Cat dealer for information regarding fixtures for proper lifting.
