Track Adjuster

The track adjuster assembly provides proper tension to the track. A slack track will lead to vibration jump when it moves and excessive slack will also cause track slippage. However, the track can't be adjusted too tightly, otherwise the friction between the track pin and pin bush or the idler would be increased, which will accelerate their wear.
