JAKE BRAKE TUNE UP KIT

This is an engine brake tune-up kit, often referred to as a Jake Brake overhaul kit, designed for the Jacobs Vehicle Systems Model 340 series engine brake installed on Caterpillar 3406E truck engines. It contains the seals, springs, spool valves, and screws needed to refresh a worn engine brake, restoring retarding power and eliminating oil leaks that commonly develop over time. You would replace these components when you notice reduced engine braking performance, visible oil seepage around the brake housings, or as part of a scheduled top-end overhaul. This kit is a genuine Caterpillar solution for a field installation tune-up on 3406E engines within the 6TS serial number prefix range.
