Lower Unit
Keep the following matters in mind when
performing the measurement.
• Shaft 1 that secures forward gear (A gear)
has been tightened so that drive shaft q
cannot be turned over backlash when it is
turned lightly.
• Fixing of drive shaft bearing e is performed
only with pump case (lower) 8. Clamp halves
A 6 and B 7 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).
