How to Spot Rubber Track Wear on Cat® Mini Excavators
Estimated read time: 2 minutes
Rubber tracks support a mini hydraulic excavator's performance, providing traction, stability and the flexibility to operate on a range of surfaces. But, like any hardworking component, they’re subject to wear and tear. Monitoring Cat® track wear can mean the difference between a productive day and costly downtime. Let’s look at some common track wear indicators, when to replace rubber tracks, and a few maintenance practices that can help extend the life of your tracks.
Check out the video and then read on for the details:
Safety First
Before you start any track inspection or maintenance, check your Operation and Maintenance Manual (OMM) for proper safety procedures. Always wear the recommended personal protective equipment (PPE) to keep yourself safe while you work.
Track Wear Factors
Several factors contribute to rubber track wear, some of which are within your control. Here’s what you should consider:
1. Application
The type of work your excavator performs can impact how long the tracks last. Heavier tasks like excavating require more torque and horsepower, putting extra strain on the tracks. In comparison, lighter jobs like trenching typically produce less wear.
2. Underfoot Conditions
What’s under your machine matters. Abrasive conditions — such as rocky terrain or gritty soil — accelerate track wear. Working on harder surfaces will wear down the tread much faster than smoother, less demanding environments.
3. Operating Technique
How you operate the machine has a direct impact on track life. Quick, sharp turns, high speeds, and operating on slopes all accelerate wear. Tasks that require frequent travel between sites also increase wear, as the rubber experiences continuous, uneven strain.
4. Maintenance Practices
Regular maintenance is key to extending track life. Ensure tracks are properly tensioned: too tight, and they’ll wear quickly; too loose, and they may slip or become misaligned. Also, clear debris from undercarriage components regularly to avoid premature wear and ensure your tracks run smoothly over different terrains.
Track Replacement Evaluation
Not sure if your rubber tracks are ready for replacement? Here’s an easy way to check:
- Place a straight edge across two of the track’s tread blocks.
- Measure the distance from the top of the tread block to the top surface of the track.
If you’re uncertain whether your measurement indicates significant wear, ask your Cat dealer for guidance. They can help you determine if it’s time for new tracks or connect you with Cat SIS 2.0, a valuable resource with detailed service instructions for your machine.
For more information and support, contact your Cat dealer. And always check your Operation and Maintenance Manual for specific instruction and safety procedures.
