3. Perform shim adjustment as necessary based on the gauge
value obtained. The table shows relation between dial gauge
readings and shim adjustments.
Gauge Reading Shim Adjustment
mm mm
0.60 - 1.00 0
1.01 - 1.15 0.1

1.
Values in this table indicate dial gauge readings
that are obtained when using special tool.
2.Change gear engagement position and
measure backlash again.
4. After the adjustment, remove backlash measuring tool, and
turn drive shaft while pulling it up to see if it turns smoothly.
If not, reduce shim thickness 0.05mm and adjust backlash
again.
If engagement of bevel (A) gear with pinion (B)
gear is imperfect, they may produce abnormal
noise when turning drive shaft while pulling it up. In
such case, reduce shim thickness 0.05mm.
Keep the following matters in mind when
performing the measurement.
· Shaft 1 that secures forward (A) gear has
been tightened so that drive shaft q cannot
be turned over backlash if it is turned lightly.
· Fixing of drive shaft bearing e is performed
only with pump case (lower) 8 . Clamp
halves A6 and B7 should be attached as
close to pump case (lower) 8 as possible.
· When performing the measurement by using
dial gauge, gear case and dial gauge are
fixed and drive shaft q is turned while it is
pulled up. During the measurement, be sure
that other parts do not produce play (play of
drive shaft q itself and the one between
drive shaft q and bearing).
