9-3. Reassembly
Push the parts together in the reverse order of disassembly, with the precautions given below.
(1) Generously lubricate the teeth of Gear [17] <17> and Pinion [6] <6> with grease. Rub grease onto the teeth
with your fingers so that the grease reaches each tooth bottom. Note that the Gear [17] <17> and Pinion [6]
<6> if under-lubricated may wear at a faster rate.
(2) Be sure to soak the inner diameter of the Felt Packing [21] <21> with machine oil. Otherwise, its dust-sealing
function will fail to work properly, resulting in an earlier damage of the Ball Bearing [20] <20>.
(3) When replacing the Armature [9] <9> or the Ball Bearing [15] <15>
at the commutator side, be sure to replace the Dust Seal [14] <14>
with new one together. The Dust Seal [14] <14> is an important part
to ensure the dust resistance of the ball bearing.
Replace the Dust Seal [14] <14> with new one without fail.
Press-fit the Ball Bearing [15] <15> to the position specified in Fig. 7.
Thrust Washer [13] <13>

4.0 mm in diameter) as shown in Fig. 8.
