When backlash readings are not within specifications, the technician may correct the backlash by adjusting the gear mesh or gear alignment. Backlash refers to the slight movement between gears when they are engaged and disengaged. If there is too much backlash, it can lead to inaccuracies in machine performance, vibration, and wear over time.

Adjusting the gear mesh involves changing the distance between gears or altering the position of one of the gears to ensure they are properly aligned. This may include tightening or loosening screws, changing shimming, or in some cases, modifying the teeth of the gears themselves. Proper adjustment is crucial for maintaining a machine's efficiency and operational precision, especially in applications such as CNC machinery, automotive engineering, and various industrial equipment where gear systems are prevalent. It is important to regularly monitor backlash to ensure optimal performance and reduce mechanical wear.
