Pinion
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 differential carrier
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) car-
rier is not true and square, or 3) gear is not properly seated on differ-
ential case. The remedy is to replace the defective member.
Irregular patterns: If the pattern is not oval, it means that bevel gear
is defective. High or low spots on tooth surfaces or on the seat of
bevel gear are the cause of irregular patterns appearing on some
teeth. The remedy is to replace the pinion and gear set and, if the
seat is defective, so is differential case.
