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.

NOTE: To correct tooth contact, increase or decrease
shims as necessary on both secondary drive and
driven gears equally. Use the "Tooth Contact/Shim
Correction" chart above for shim selections.

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