Mini excavator undercarriage Yanmar B22 track roller / bottom roller
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.
