9. Remove the snap ring securing the water pump
driven gear shaft.
10. Using a hydraulic press, remove the crankshaft
assembly.
 NOTE: Use a protective end cap to prevent damage
to the crankshaft threads.
11. Remove the cap screws securing the oil strainer cap;
then remove the cap.
12. Remove the two cap screws securing the oil strainer;
then remove the strainer.
 NOTE: Thoroughly clean any sealant from the oil
strainer cap.
CAUTION
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.
13. To remove the secondary drive/bevel gear, remove
the secondary drive bearing housing; then remove
the nut securing the drive/bevel gear shaft in the
bearing and using a plastic mallet, drive the shaft out
of the bearing. Account for shim/shims.
 NOTE: Shims should be measured and kept for a
starting point in adjusting backlash.

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
CD832B
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.
2. Using a suitable press, install the driven gear (C) on
the shaft until the gear firmly seats on the shoulder of
the shaft.

3. If installing the existing shaft, start with the shims
removed during disassembly or if installing a new
shaft, start with approximately 1.0 mm shims at point
(D); then install the output drive shaft bearing (E)
making sure the locating pin is directed toward the
center of the shaft.
