< 2 > Disassembling spiral bevel gear 9 and armature
(1) Remove tapping screw 4x18 and separate rear cover from motor housing.
And remove carbon brush as illustrated in Fig. 1.
(2) Remove tapping screw 4x28 and detach gear housing from motor housing.
And remove armature with gear housing cover as illustrated in Fig. 1.
(3) Disassemble retaining ring S-6 and flat washer 6 from armature shaft as illustrated in Fig. 1A.
(4) Grip spiral bevel gear 9 with your gloved hand, and pull off spiral bevel gear 9 with turning anti-clockwise.
Then, flat washer 12 and lock spring 12 can be separated from armature shaft together with spiral bevel gear 9
as illustrated in Fig. 1B.
(5) Disassemble spiral bevel gear 9 with No. 1R269 "Bearing extractor" as illustrated in Fig. 1C, if it is difficult to
disassemble with hand.

< 4 > Disassembling gear section
(1) Separate gear section by unscrewing 4 pcs. of hex socket head bolts M4 x 16 as illustrated in Fig 3.
It is recommended to unscrew hex socket head bolts M4 x 16 with impact driver,
because they are adhesive bolts.
(2) Put gear section on No.1R217 "Ring 22". And disassemble spindle from spiral bevel gear 35 by pressing
with arbor press as illustrate in Fig. 3A.
(3) Disassemble bearing retainer by turning anti-clockwise as illustrate in Fig. 3B.
< Note >
For disassembling bearing retainer, remodel No.1R043 "Wrench for bearing retainer" by expanding the distance
between the spikes from 20mm to 21 or 22mm as illustrated in Fig. 3C.
(4) Disassemble ball bearing 6201DDW by slightly hitting the edge of bearing box with plastic hammer
as illustrate in Fig. 3D.
