TOOTH CONTACT PATTERN DIAGNOSIS AND REMEDY
NORMAL
HIGH CONTACT
Pinion is positioned too far from the
center of drive bevel gear.
3) Increase thickness of pinion height
adjusting shim and position pinion
closer to gear center.
4) Adjust drive bevel gear backlash to
specification.
LOW CONTACT
Pinion is positioned too close to the
center of drive bevel gear.
1) Decrease thickness of pinion height
adjusting shim and position pinion
farther from gear center.
2) Adjust drive bevel gear backlash to
specification.
These contact patterns indicate that the "offset" of dif-
ferential is too much or too little. The remedy is to
replace the carrier with a new one.
These contact patterns, located on toe or heel on both
drive and coast sides, mean that 1) both pinion and
gear are defective, 2) carrier is not true and square, or
3) gear is not properly seated on differential case. The
remedy is to replace the defective member.
