Reverse the disassembly procedure to reassemble. Note the following points.
(1) Rub grease into the teeth of the Gear and Pinion Set [25]<25> with your fingers so that the grease
reaches each tooth bottom. Note that under-lubricated Gear and Pinion Set [25]<25> may wear at a
faster rate.
(2) When replacing the Armature [24]<24> and the Ball Bearing 698SS [32]<32> on the commutator side,
press the Dust Seal [31]<31> in while carefully noting its direction until the end face of the Dust Seal
[31]<31> contacts the butting surface of the Armature [24]<24>, and check that the Dust Seal [31]<31>
cannot turn freely. (See Fig. 3.) The Dust Seal [31]<31> is an important element for improved dust
protection of the Ball Bearing 698SS [32]<32>. Be sure to replace the Dust Seal [31]<31> with new one
at every disassembly work. Fit the Rubber Bushing [33]<33> into the housing ball bearing chamber
before installing the Armature [24]<24>. (See Fig. 4.)

(3) When installing the Stator [30]<30> into the Housing [34]<34>, insert it while being careful about
correctly placing the internal wires of the Stator [30]<30> as shown in Fig. 5. Connect the four internal
wires of the Stator [30]<30> correctly as shown in Fig. 6.
NOTE: • Be careful not to put the internal wire of the Carbon Brush (1 Pair) [38]<38> on the top of
the Brush Holders [36]<36> when connecting the internal wires of the Stator [30]<30> or
when connecting the Carbon Brush (1 Pair) [38]<38>.
• Each internal wire of the Stator [30]<30> is covered with a glass tube. Do not bend the
internal wires repeatedly and do not peel off the glass tubes when mounting the Stator
[30]<30> to the Housing [34]<34>. Otherwise, the internal wires may be disconnected.
• Do not apply excessive force to the terminals of the Stator [30]<30> when inserting them
into the Pushing Button Switch [40]<40> and Brush Holders [36]<36>. Otherwise, the
terminals of the Stator [30]<30> may be broken.
