Installation & Maintenance Precautions

Critical Safety Warning: Track assemblies are extremely heavy (over 500kg per side). Always use proper lifting equipment (crane or forklift) during installation and removal. Never work under an unsupported excavator.
Pressure Release: Before any track work, slowly loosen the grease fitting on the track adjuster cylinder to release all internal pressure until the track is completely slack.
Pre-Installation Inspection: Thoroughly inspect the track frame, idlers, rollers, and sprockets for cracks, deformation, or excessive wear. Replace any damaged components before installing the new track chain.
Master Link Installation: Ensure the master link is properly aligned and torqued to the specified value. Never reuse old master link bolts.
Track Tension Adjustment: After installation, adjust the track sag to 30-40mm (measured between the bottom roller and the track shoe). Excessive tension accelerates undercarriage wear, while excessive looseness causes derailment.
Regular Inspection: Inspect the track chain every 250 operating hours for:
- Excessive pin and bushing wear
- Loose or missing track shoe bolts
- Oil leakage from the seals
- Bent or broken links
Replacement Best Practice: For maximum service life, always replace the entire undercarriage system (track chains + sprockets + rollers + idlers) at the same time. Mismatched components will cause accelerated wear to all parts.
