NOTE
•
Location of good hand-rolled contact pattern for new gear set is toward toe of gear tooth and in center
between top and bottom of tooth.
•
Location of good hand-rolled contact pattern for used gear set must match wear pattern in ring gear.
Contact pattern will be smaller than wear pattern.
•
During tooth contact pattern checks, backlash can be adjusted within specification limits, if needed, to
change pattern location.
66.
Compare contact pattern with examples shown.
67.
If contact pattern requires adjustment, perform disassembly steps 38,39, and 43 through 45.
68.
Remove inner bearing cup (62) and shim pack (63).
69.
To correct high contact pattern, add shim(s) to shim pack (63).
70.
To correct low contact pattern, remove shim(s) from shim pack (63).
71.
Perform steps 8 through 66 to determine contact pattern.
72.
If contact pattern is too far toward heel of gear teeth, repeat step 62 to decrease backlash to move pattern toward toe of
gear teeth.
73.
If contact pattern is too far toward toe of gear teeth, repeat step 61 to increase backlash to move pattern toward heel of
gear teeth.
74.
Install pin (46) in bearing caps (44 and 45) so that pin is between lugs of adjusting ring (48).
