Drive Pinion, Ring Gear Tooth Contact Inspection

Drive Pinion, Ring Gear Tooth Contact Inspection
1. Apply tooth marking compound evenly to both surfaces of the ring gear.
2. Rotate the ring gear back and forth for several times.
3. Inspect the tooth contact pattern in 4 locations around the ring gear, and verify that the tooth contact points exhibit the pattern shown in the figure.
^ If the tooth contact points are normal, wipe off the marking compound,





^ If the tooth contact points are not normal, adjust the pinion height, then adjust the backlash.





4. If the toe and flank contact points appear as shown in the figure after the drive pinion and ring gear teeth contact inspection, replace the spacer with a thinner one, and move the drive pinion outward.





5. If the heel and face contact points appear as shown in the figure after the drive pinion and ring gear teeth contact inspection, replace the spacer with a thicker one, and move the drive pinion inward.
