Top Rollers & Your Mini Excavator’s Undercarriage System

Top rollers support the track along the upper frame of the undercarriage.
Understanding Top Roller Function
Within the intricate undercarriage of your CAT 305.5E2CR Mini Excavator, top rollers ensure the track maintains its proper path along the top of the track frame. Without them, the track would sag significantly, potentially hitting the frame or other components, and increasing the likelihood of de-tracking.
The condition of your top rollers impacts:
- Track Alignment: Worn or seized top rollers can cause the track to misalign.
- Overall Undercarriage Wear: A failing top roller puts additional stress on other components.
- Operational Noise: Damaged rollers can be a source of excessive noise.
Regular inspection of top rollers for signs of wear, damage, or seizure (inability to turn freely) is an important part of undercarriage maintenance. Replacing them when necessary helps ensure the longevity and reliability of your entire system, keeping your CAT 305.5E2CR Mini Excavator running smoothly.
