Note;
Press Bearing case complete with Arbor press softly and
do not press further when it is stopped.
Otherwise, the position of Pinion gear on the DC motor
may deviate.
(2) Insert Push plate into dust seal and assemble Push plate to Bearing case complete.
And then, mount Balance plate (Fig. 4).
(3) Assemble Gear complete to the pin on the Bearing case complete (Fig. 4-7).
Note;
Shake Push plate up and down while pressing Gear complete to insert it completely and to have the assembling groove
of Retaining ring S-6 on the Pin of Bearing case complete. Fix Retaining ring S-6 to secure Gear complete
to the pin’s groove (Fig. 6).
