1686684 Adjustment Gp-Hydraulic Track — Cat 311c 312c L

This hydraulic track adjustment group is a sophisticated component within the undercarriage system, utilizing hydraulic pressure to automatically maintain optimal track tension. It ensures consistent performance and reduces wear by compensating for track stretch and wear. Operators may experience erratic track tension, increased vibration, or unusual noises from the undercarriage when this system is not functioning correctly.

Failure Symptoms

Initial symptoms of a malfunctioning hydraulic track adjuster may include inconsistent track tension, where the track feels too loose or too tight, and audible clicking or grinding sounds. A significant leak in the hydraulic seals will result in a progressively slack track, increasing the risk of derailment and damage to the track chain and rollers. Failure to address these issues can lead to premature wear on all undercarriage components and compromise machine stability.

Installation Tip

Thoroughly clean the hydraulic lines and cylinder bore before connecting the new adjuster to prevent contamination of the hydraulic system. Ensure the correct hydraulic fluid type and level are used as specified in the service manual.

Service Note

Inspect the idler, recoil springs, and track chain for wear and damage when replacing the hydraulic track adjustment group.
