Application: Hydraulic track adjuster — the spring-loaded hydraulic cylinder assembly that maintains correct track tension by controlling front idler position on applicable Caterpillar mid-size and large excavators. Absorbs shock loads from the track system during travel and operation to protect the front idler, track chain, and undercarriage components
Note: Verify your machine's serial number prefix and configuration before ordering — confirm part number match for your specific machine serial range
Common Use Case or Symptoms: Use when the track adjuster is leaking grease, the track is running loose despite regreasing, the recoil spring has collapsed, or the cylinder rod is bent or scored — a failed track adjuster causes improper track tension, accelerated track and idler wear, track derailment risk, and poor machine travel performance on applicable Caterpillar excavators.
