Failure Symptoms

The first indication of a failing spring is often a loss of consistent track tension, leading to a looser track and a less stable ride. If left unaddressed, the spring can weaken further, causing increased shock to the undercarriage and potential damage to other components. Continued operation with a compromised spring can lead to premature wear on the track system and other undercarriage parts.

Installation Tip

Before removing the old spring, ensure the track tension is safely released according to the service manual procedures. Avoid forcing the new spring into place; ensure all mounting points align correctly to prevent damage.

Service Note

Inspect the track adjuster assembly, recoil cylinder, and all associated seals and hardware when replacing this spring.
