Mini excavator undercarriage Yanmar B3-3 sprocket

Mini excavator track roller / bottom roller

The idler wheels are a fundamental component of the undercarriage.

As well as transferring some of the track frame loads into the tracks , their key function is to feed the tension from the adjuster into the tracks. Failure will :

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

2 . Result in a loss of track tension.

3 . Accelerate track wear.

4 . Increase the point loadings on rollers, thereby increasing peak ground bearing pressure.
