4i7342 Spring Gp-Recoil — Cat 311 311B

This is a CAT Recoil Spring Group, designed to absorb shock and maintain proper track tension in the undercarriage system. Manufactured to meet rigorous OEM specifications, it offers superior resilience and longevity over a worn spring that has lost its elasticity. Operators might observe a loose or slack track, increased vibration, or a rougher ride when this recoil spring begins to weaken or break.

Failure Symptoms

A failing recoil spring will first manifest as a noticeably slack track that may bounce or sag excessively. Over time, this looseness can lead to increased wear on other undercarriage components and a rougher, less stable machine operation. Continued use with a compromised recoil spring risks track derailment and potential damage to the machine's structure.

Installation Tip

Ensure the recoil cylinder and associated components are properly cleaned and lubricated before assembly. Be extremely cautious when releasing tension on the recoil system, as stored energy can cause injury.

Service Note

Inspect recoil cylinder seals, track carrier rollers, and the track chain for wear and proper function when replacing the recoil spring group.
