Bottom Rollers


Bottom rollers are designed to take transfer the majority the excavators weight and dynamic forces, through the tracks, and onto the ground.


Check for wear on a regular basis. It is best to replace all the bottom rollers on one side.

If only one roller per side is changed, then as the new roller may be slightly larger in diameter it will carry a higher load and have a shorter life.


Backlash or play in the bottom rollers will:


1 . Reduce the excavator’s stability.

2 . Increase the point loadings of less worn rollers, thereby increasing peak ground bearing pressure.

3 . Accelerate track wear.

4 . Increase the likelihood of de-tracking and subsequent damage to tracks.

5 . Increase the load on the track motor and gearbox.
