Tightening Torque - Hitachi G 10SS2(S) Service Manual

(3) Before inserting the Stator [9]<9> into the Housing [26]<25>, correctly connect the internal wires of the
Stator [9]<9> to each part without entangling as shown in Fig. 4.
NOTE: • Be careful not to put the internal wire of the Carbon Brush [27]<26> between the
Housing [26]<25> and the internal wires of the Stator [9]<9> when connecting the
internal wires of the Stator [9]<9> or when connecting the Carbon Brush [27]<26>.
• The internal wire (single wire) of the Stator [9]<9> is covered with a heat-shrinkable
tube. Do not forcefully bend the internal wire of the Stator [9]<9> repeatedly and do
not peel off the heat-shrinkable tube when mounting the Stator [9]<9> to the Housing
[26]<25>. Otherwise, the internal wire may be disconnected.
• Do not forcefully bend the stator terminal when inserting the stator terminal into the
Pushing Button Switch [32]<31> and the tab terminal. Otherwise, the stator terminal
may be broken.
