May 19, 2022Afterwards, the pinion must be aligned to the gear through measuring the gear root clearance, not the backlash. This is due to the backlash being unreliable due to profile wear on the used gear and/or the used pinion. Proper attention to the pinion to gear offset must also be considered. This is process is referred to as a static alignment.
