Undercarriage Wear
Quick definition
Undercarriage wear is the deterioration of tracked-machine running-gear components through use. Inspection and wear measurement help plan service for the actual machine.
What wears on a tracked machine?
Tracked undercarriages contain components such as track links, shoes, rollers, idlers and sprockets, depending on design. Work conditions and operating practices affect wear patterns. A remote hour reading alone does not establish remaining component life.
Measure before setting a replacement plan
Caterpillar describes dealer wear inspections that measure components and report wear patterns. Use qualified measurements and the applicable component specifications to plan repair or replacement. Keep the measurement date and machine context with the record.
What to verify
There is no universal wear percentage or replacement hour suitable for every machine. Follow the relevant manual and qualified service guidance. Do not infer a diagnosis or service threshold from a glossary description.
