Track Assembly for Liebherr R9350 Excavator
Product Overview
The track assembly is a critical undercarriage component of your Liebherr R9350 mining excavator, providing ground contact, propulsion, and weight distribution for this massive 300-ton class machine. The track assembly consists of track shoes (pads), track links, bushings, pins, and master links, working together to transfer the excavator's weight to the ground while enabling smooth travel across mining terrain.
The Liebherr R9350 is a 300-ton class mining excavator powered by two Liebherr diesel engines or electric drive options. This genuine Liebherr track assembly is engineered to exacting OEM specifications for perfect fit, reliable performance, and maximum service life in demanding mining environments.
This is a genuine Liebherr original equipment part.

Installation Guidelines
Critical Requirements
- Verify part numbermatches your machine's requirements
- Prepare adequate heavy lifting equipment- Track assembly is extremely heavy
- Support machine securelywith blocking
- Relieve track tensionbefore removal
- Use proper track toolsfor master link and shoe removal
Installation Steps
- Position machine on level ground, block securely
- Relieve track tension using track adjuster
- Remove master link to break track chain
- Remove old track assembly
- Clean sprocket, rollers, and idler surfaces
- Inspect undercarriage components for wear
- Position new track assembly around undercarriage
- Connect master link to join track chain
- Apply track tension to specification
- Test track operation in forward and reverse
- Re-torque master link bolts after initial operation
- Re-check tension after test operation
Post-Installation
- Verify smooth track operation
- Check for proper sprocket engagement
- Inspect for unusual noise
- Monitor track tension during initial operation
- Re-tension after break-in period
IMPORTANT:Installation must only be performed by qualified mining equipment technicians following procedures in the Liebherr R9350 Workshop Manual.
Maintenance Recommendations
Interval
Maintenance Task
Daily
Visual inspection for damage, check track tension
Weekly
Inspect track shoes for wear or damage
Monthly
Check for loose track shoe bolts
Every 500 hours
Measure track sag, adjust tension as needed
Every 1000 hours
Inspect pins and bushings for wear
Every 2000 hours
Measure track chain wear (pin/bushing elongation)
As Needed
Replace worn track shoes, pins, and bushings
Critical Notes
- Proper track tension is critical for component life
- Undercarriage wear is the single largest maintenance cost on mining excavators
- Regular pin and bushing measurement extends track life
- Worn tracks accelerate sprocket, roller, and idler wear
- Replace undercarriage components in sets for even wear
