Adjust the shim thickness after replacing the gear case, vertical
shaft, bearing, taper bearing and the taper roller bearing.
a. PINION GEAR SHIM
Remove the 30 x 62 x 40 mm taper roller bearing if it is
mounted on the vertical shaft (P. 14-70).
1) Wipe the tapered part of the vertical shaft and the pinion
gear with a shop towel and a degreasing cleaning solvent.
2) Install the pinion gear on the vertical shaft and tighten the
pinion gear nut to the specified torque.
TORQUE: 142 N.m (14.5 kgf.m, 105 lbf.ft)
• Do not install the vertical shaft in the gear case.
• We recommend that you attach the special tool (vertical
shaft holder) at the end of the vertical shaft to facilitate
tightening of the pinion gear nut to the specified torque
(P. 14-76).
3) Do not confuse the pinion gear side and the taper roller
bearing side of the special tool.
Do not score and scratch the opposite side (measurement
side) from the side where the tool number is stamped.
TOOL:
Gauge adapter, 110 mm

4) Holding the special tool with the side of the stamped tool
number facing the opposite side from the pinion gear, be
sure that the tool of the pinion gear nut side is not set on
the nut.
Tighten the bolts by hand while pushing both tools toward
the pinion gear side.
• Do not tighten the bolts with a tool.
• There must be no wobbling in the special tool. It must
securely set on the pinion gear.
