GEAR CASE (STANDARD ROTATION)
PINION GEAR SHIM
Remove the taper roller bearing (32 x 66 x 49 mm) if it
is mounted on the vertical shaft [1] (page 16-32).
Clean the tapered surfaces [1] of the vertical shaft [2]
and pinion gear [3] thoroughly using a shop towel and
degreasing cleaning agent.
Apply gear oil to the threads and seating surface of the
pinion gear nut [4].
Install the pinion gear on the vertical shaft.
Tighten the pinion gear nut to the specified torque using
the special tool.
Use a vernier caliper [1] to measure distance (D) [2]
from the end of the pinion gear to the end of the flange
of the vertical shaft as shown. Record this
measurement.
Assemble the outer race [1] and the inner race [2] of the
taper roller bearing (32 x 66 x 49 mm), and turn the
outer race two or three turns to fit the bearings.
Remove one side of the inner race and measure the
bearing height (E’) from the outer race end to the inner
race end using a regular vernier caliper [3] as shown,
and record the measurement.
