(2) Disassembly of the dust seal
1. Insert the hooks of the J-204 bearing puller between the commutator and the Dust Seal (A) [17] from both
sides, and fix the hooks with the wing bolts.
2. Place the J-204 bearing puller on a supporting jig and push down on the armature shaft with a hand press to
remove Dust Seal (A) [17] together with the Ball Bearing 608VVC2PS2L [18]. Replace Dust Seal (A) [17]
with new one because it is damaged by the removal of the Ball Bearing 608VVC2PS2L [18].
(3) Disassembly of the stator
1. After removing the Armature [12] and Switch Box [44], disconnect the lead wires connected to the Brush
Holders [52].
2. Loosen the two Hex. Hd. Tapping Screws D4 x 70 [14] and remove the Stator [15] from the Housing [41].
If the Stator [15] cannot be easily removed from the Housing [41], disassembly can be facilitated by heating
the Housing [41] to a temperature of approximately 60˚C (140˚F) with an appropriate heating device.
(4) Disassembly of the gear (Fig. 6)
1. Loosen the four Seal Lock Screws (W/Sp. Washer) M5 x 16 [26] fixing the Packing Gland [25], and remove
the Packing Gland [25] from the Gear Cover Ass'y [4].
2. Support the bottom of the Packing Gland [25] with a jig, and push down on the upper portion of the Spindle
[28] with a hand press until the end surface of the Feather Key 3 x 3 x 8 [27] contacts the Ball Bearing
6201DDCMPS2L [23] and the Spindle [28] cannot be pushed down any more.
3. Turn the Packing Gland [25] upside down and fix it, then push down the Spindle [28].
4. Insert the steel plate between the Gear [20] and the Packing Gland [25], and push down the Spindle [28] with
a hand press to remove it.
Replace the Ball Bearing 6201DDCMPS2L [23] with new one every time should the gear be disassembled
because the stress while pulling out the gear is applied to the Ball Bearing 6201DDCMPS2L [23].
