Correcting Tooth Contact
 NOTE: If tooth contact pattern is comparable to the
correct pattern illustration, no correction is necessary.
If tooth contact pattern is comparable to an incorrect pat-
tern, correct tooth contact according to the following
chart.
Tooth Contact
Contacts at Top
Contacts at Root
Shim Correction
Increase Shim Thickness
Decrease Shim Thickness
NOTE: To correct tooth contact, increase or

decrease shims as necessary on both secondary drive
and driven gears equally. Use the "Tooth Con-
tact/Shim Correction" chart above for shim selec-
tions.
CAUTION

checked and corrected (if necessary). Continue the cor-
recting backlash/correcting tooth contact procedures
until they are both within tolerance values.
