SECONDARY OUTPUT DRIVE GEARS
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 contact. If
only the secondary output drive shaft or secondary
output driven gear is replaced, proceed 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.

Unless the secondary drive gear, bevel gear, or bear-
ings require service, do not remove the secondary drive
assembly from the case. If removed, bevel gear back-
lash will have to be adjusted requiring re-shimming of
the drive bevel gear shaft.
