2540623 Spring-Recoil — Cat D3K XL D3K2 LGP

This recoil spring is a vital component in the undercarriage system, providing tension to the track chain and maintaining proper track alignment. Manufactured to precise specifications, it offers consistent tension and durability, unlike a weakened or broken spring that allows excessive track slack. Operators may notice the track becoming loose, derailing, or excessive vibration and noise from the undercarriage when this spring fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The initial symptom of a failing recoil spring is a noticeable loosening of the track, which may begin to sag excessively. If ignored, the loose track can increase wear on undercarriage components and may eventually lead to the track derailing, especially during turns or on uneven terrain. A completely failed spring will result in a very loose track, significantly increasing the risk of derailment and potential damage to hydraulic lines or fenders.

Installation Tip

Carefully release the tension on the old spring before attempting removal to avoid sudden release of stored energy. Ensure the new spring is correctly seated in its mounts before applying tension to prevent misalignment.

Service Note

Inspect the recoil cylinder, front idler, and track chain for wear or damage while the recoil spring is being replaced.
