Question

Quizplus · Accepted Answer

Both Technician A and Technician B are correct. A gear tooth pattern can indeed identify a backlash problem as well as issues with the pinion depth. The pattern formed by the contact between the ring and pinion gears can indicate if the gears are too close or too far apart (backlash issue) or if the pinion gear is not set at the correct depth relative to the ring gear.
