(4) Disassembly of the gear
1) Loosen the four Seal Lock Screws (W/Sp. Washer) M4 x 12
[10]
that secure the Packing
Gland
[9]
to the Gear Cover Ass’y
[2]
, and then remove the Packing Gland
[9]
from the
Gear Cover Ass’y
[2]
.
2) Remove the Retaining Ring For D11 Shaft
[3]
that secures the gear to the Spindle
[12]
.
3) Remove the Wave Washer
[4]
and the gear from the Spindle
[12]
.
1-2. Reassembly
Conduct reassembly by reversing the disassembly procedure, and note the precautions given
below.
(1) Ensure that the terminals of the stator are not bent or otherwise damaged.
(2) Generously lubricate the teeth of the gear and pinion with grease. Rub grease onto the
teeth with your fingers so that the grease reaches the bottom of each tooth. Note that
insufficient lubrication may cause the gear and pinion to wear faster than normal.
(3) Be sure to soak the inner diameter of the Felt Packing
[8]
with machine oil. Otherwise, its
dust-sealing function will fail to work properly, resulting in premature damage to Ball
Bearing 6201VVCMPS2L
[7]
.
(4) When replacing the Armature
[24]
and Ball Bearing 626VVC2PS2L
[30]
on the commutator
side, press inward on the Dust Seal
[29]
while carefully noting its direction until the end face
of the Dust Seal
[29]
contacts the end surface of the Armature
[24]
. Also make sure that
Dust Seal
[29]
cannot be freely turned by hand. Keep the end face of the armature shaft
about 0.2 mm (reference) inside the end face of Ball Bearing 626VVC2PS2L
[30]
(see Fig.
1
).
The Dust Seal
[29]
is an important element for improved dust protection of Ball Bearing
626VVC2PS2L
[30]
. Be sure to replace it with a new one each time.

(5) When connecting the Earth Terminal
[40]
to the internal wire (the middle wire among
three) of the Noise Suppressor
[45]
, strip off about 6 mm of the insulation sheath on the
internal wire, and then use a commercially available clamping tool to press-connect the
wire with the Earth Terminal
[40]
.
