Description of Change:
Show/hide table
Illustration 1 | g03437578 |
358-9475, 358-9476 Breaker Relief Valve As (1) Screw |
An improved breather assembly is now used on certain Cat® machines. The improved breather assembly has been redesigned to add four screws to secure the cap to the breather assembly. Securing the cap to the breather assembly prevents the cap from falling off the breather and allowing contamination of the hydraulic system.
Adaptable To:
The improved 358-9475 and 358-9476 Breaker Relief Valve Assemblies (breather assembly) have been modified to prevent loss of the cap. The effectively for this change is listed in the table that follows.
