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
pattern, correct tooth contact according to the follow-
ing chart.
NOTE: To correct tooth contact, steps 1 and 2
(with NOTE) of “Correcting Backlash” must be fol-
lowed and the above “Tooth Contact/Shim Correc-
tion” chart must be consulted.
SECONDARY OUTPUT DRIVE
GEARS (Net-Forged)
Initial Set-Up
NOTE: If the secondary output driven shaft is
replaced or disassembled, the initial set-up must
be performed to establish correct gear tooth con-
tact. If only the secondary output drive shaft or
secondary output driven gear are replaced, pro-
ceed to Correcting Backlash in this sub-section.
1. Install a new bearing (A) onto the secondary
driven shaft (B) making sure the bearing locating
groove is directed away from the driven gear
splines.

2. Using a suitable press, install the driven gear (C)
on the shaft until the gear firmly seats on the
shoulder of the shaft.

! CAUTION
After correcting tooth contact, backlash must again
be checked and corrected (if necessary). Continue

cedures until they are both within tolerance values.
