Good To Know

Q: How many bottom rollers does my excavator need? A: Count the roller stations on each side of the crawler frame and replace worn rollers in matched sets where possible. Inspect the track chain and top rollers at the same time for even wear.

Q: Can I replace just one bottom roller? A: Single roller replacement is done, but pairing rollers on the same side helps keep track wear even. Confirm the model and serial number before ordering to verify fit.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
