Set The Gear Mesh:
To set the gear mesh, push the teeth of the motor
mount cam #21531 into the corresponding tooth
pattern of the motor mount insert. Once the teeth
are seated, you should be able to rock the spur gear
back and forth without making the pinion gear move.
Exessive amounts of spur gear movement (loose
gear mesh) will cause premature gear failure. If the
spur gear mesh is tight, there will be no movement
between the spur and pinion gears. A gear mesh that
is too tight or too loose will reduce power and
damage the gear teeth.
