14) Set dial gauge to bevel pinion mounting dummy and
make 0 (zero) adjustment on surface plate.
NOTE
• When setting dial gauge to mounting
dummy, tighten screw lightly. Be careful
not to overtighten it, which will cause
damage to dial gauge.
• With dial gauge set, turn dummy back and
forth by hand a couple of times and attain
accurate 0 (zero) adjustment.
• It is desirable that short pointer indicates
beyond 2 mm when long one is at 0 (zero).
15) Place zero-adjusted mounting dummy (1) and dial
gauge set on pinion dummy (2) and take
measurement between zero position and extended
dial gauge measuring tip.
NOTE
• Repeat turning back and forth of dummy
and measure distance as far as top surface
of pinion dummy accurately.
• When dial gauge measuring tip extends
from 0 (zero) position, pointer turns
counterclockwise.
16) Necessary adjusting shim thickness is the same
value as measured value by dial gauge.
17) Select adjusting shim(s) (2) closest to obtained value
from among the following available sizes and put it in
place and then press-fit rear bearing (1) to bevel
pinion (3).
Available shim thickness
0.30, 0.60, 0.63, 0.66, 0.69, 0.72, 0.75, 0.78, 0.81,
