Tooth contact pattern

High contact
Pinion is positioned too far from the center of drive bevel
gear.
1. Decrease thickness of bevel pinion shim and position
pinion closer to gear center.
2. Adjust drive bevel gear backlash to specification.
I3RH01332045-01
Low contact
Pinion is positioned too close to the center of drive bevel
gear.
1. Increase thickness of bevel pinion shim and position
pinion farther from gear center.
2. Adjust drive bevel gear backlash to specification.
I3RH01332046-01
These contact patterns indicate that the "offset" of
reduction driven gear is too much or too little. The
remedy is to change the division of the bevel gear
shim(s).
I3RH01332047-01
These contact patterns, located on toe or heel on both
drive and coast sides, mean that 1) both pinion and gear
are defective, 2) retainer is not true, or 3) gear is not
properly seated on transfer case. The remedy is to
replace the defective member.
I3RH01332048-01
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 transfer case.
