How do I know when my Kobelco track roller needs replacement?
Excessive noise during operation
Heat buildup – a roller that becomes significantly hotter than others may have internal bearing issues
Oil leakage from seals or visible cracks on the roller surface
Uneven track tension or misalignment
Excessive play or looseness – a good roller should be snug when turned by hand; loose or sloppy rollers indicate worn bushings
