1686687 Spring Gp-Recoil — Cat 311c 312c L

This is a recoil spring group (Spring Gp-Recoil) that functions to absorb shock and maintain proper tension within the undercarriage system of compatible Caterpillar excavators. Manufactured to meet stringent OEM specifications, it offers superior resilience and longevity over worn components that have lost their elastic properties. Operators might observe a rougher ride, increased undercarriage noise, or a tendency for the tracks to feel loose when this component begins to degrade.

Failure Symptoms

Initial signs of a failing recoil spring group may include a more pronounced jolt when the machine encounters obstacles or a general feeling of looseness in the tracks. Continued operation with a degraded spring can lead to uneven track wear and potential track derailment, compromising operational safety.

Installation Tip

Ensure all safety precautions are taken to manage the stored energy within the recoil system before disassembly. Do not force components into place; ensure proper alignment to prevent damage to the spring or surrounding structures.

Service Note

When replacing the recoil spring group, it is advisable to inspect the track recoil cylinder, idlers, and track frame for any signs of wear or damage.
