[How to check the meshing condition of the motor pinion, idle gear set and ring gear (E)]
Turn the tip of anvil (A) with a hand in the above (8) condition. If the gear of the motor pinion is locked
and cannot be turned, the gear meshes improperly. Mount the Motor
[28]
to the mechanical ass'y again
properly and check the meshing condition holding the mechanical ass'y and the Motor
[28]
securely so
that the mechanical ass'y and the Motor
[28]
are fixed to housing (A).
