Abstract

Undercarriage is a critical system in crawler dozers because it supports machine load and transfers traction forces to the working surface. Track links are continuously exposed to friction, load, impact, and abrasive ground conditions, making wear monitoring important for maintenance planning. This study analyses the dimensional wear of track links on a Caterpillar D8R dozer and compares a Caterpillar track link on the left side with an Original Equipment Manufacturer (OEM) track link on the right side. The study was conducted at TSA Melak Site, Muara Bunyut, West Kutai, Indonesia, from May to June 2024. Data were collected through field observation, dimensional measurement using a depth gauge, and inspection records. The new track link height was 166 mm, and the wear limit was 149 mm. At the latest inspection, the Caterpillar track link height was 152 mm at SMR 46,102, while the OEM track link height was 153 mm at SMR 45,723. The calculated wear-allowance utilisation was 82.35% for the Caterpillar component and 76.47% for the OEM component. Thus, the Caterpillar track link was closer to its dimensional wear limit than the OEM component. The study also shows that recorded CTS indices should not be treated as equivalent to dimensional wear percentages when their calculation parameters are unavailable. The results can support condition-based monitoring and maintenance prioritisation of track link components.
