[3]-1. Replacing Armature and Ball Bearing 6201LLB
[3] Disassembling and Assembling
1) After removing Carbon brushes, Remove Grip 36 complete.
Separate Head cover from Gear housing by removing two M14x10
(+) Round head screws with Phillips screwdriver No.3 or the like.
2) Separate Gear housing section from Motor housing by removing
four 5x30 Tapping screws.
3) Slide Gear housing cover until you see the corners on the end of
Motor housing. And then by striking two of the corners with plastic
hammer, the assembly of Armature and Gear housing cover can be
separated from Motor housing. (Fig. 2)
4) Remove Hex nut M6 by turning counterclockwise while holding
Armature firmly by hand. Now smaller Spiral bevel gear can be
removed from Armature shaft by hand.
4) Remove Gear housing cover from Armature using Gear Extractor,
large (No.1R045). (Fig. 3) Ball bearing 6201LLB is still on Gear
housing cover at this step. Therefore, remove the bearing with
arbor press and a round bar. (Fig. 4)
Note: Disassembling can be done without disassembling Gear
housing section.
CAUTION: For your safety, before maintenance or repair, be sure to;
1. Disconnect the machine from the power source.
2. Remove the wheel from the machine.

[2]- 2. Replacing Spiral Bevel Gear 43 and Ball Bearing 6202DDW
1) Insert ball bearing 6201LLB straight into Gear housing cover.
And then put Bearing setting plate (No.1R035) on arbor press, and then put Gear housing cover on Bearing setting plate.
Press-fit Armature to Gear housing cover using arbor press. (Fig. 5)
2) Install smaller Spiral bevel gear on Armature shaft, and tighten Hex nut M6 securely with a spanner 10.
And then install the assembly of Armature and Gear housing cover on motor housing, and align the screw holes on Gear
housing cover with those of Motor housing.
3) Aligning the protrusion on gear housing with that on Motor housing, fit Gear housing to gear housing cover. (Fig. 6)
Fasten Gear housing to Gear housing cover and Motor housing with four 5x30 Tapping screws.
4) Install Head cover and Grip 36 complete.
1) Remove Sanding pad.
2) Using a Makita impact driver and Hex shank bit M5 (No. 1R229), remove four M5x16 Hex socket bolts that fasten
Bearing box to Gear housing.
3) Insert two slotted screwdrivers into two diagonal positions on the slit between Bearing box and Gear housing.
And twist the two screwdrivers at the same time till Bearing box is lifted up approximately 3mm.
And then insert the screwdrivers further into the slit, and remove Gear housing from Gear housing cover by lifting it
up with the screwdrivers. (Fig. 7)
Follow the reverse of disassembling procedure as described below.

[3]- 2. Replacing Spiral Bevel Gear 43 and Ball Bearing 6202DDW (cont.)
[3]- 3. Replacing Shaft Lock Section
3) Remove Ball bearing 608LLB from spindle using Bearing extractor (No.1R269) as illustrated to left in Fig. 8.
4) Remove Retaining ring S-15 from Spindle using Retaining ring S and R pliers (No.1R291) as illustrated
to right in Fig. 8. Now Spiral bevel gear 43 and Woodruff key can be removed from Spindle by hand.
5) Remove spindle by pushing with Gear Extractor, large (No.1R045). (Fig. 9)
6) Hold Bearing box securely with vise, and remove
Bearing retainer from Bearing box using Bearing
retainer wrench (No.1R340) as illustrated in Fig. 10.
7) Remove Ball bearing 6202DDW from Bearing box
by hitting it straight against the surface of work bench.
If cannot be removed, use arbor press.

DISASSEMBLING
Follow the reverse of disassembling steps.
Note: When installing Spiral bevel gear 43 onto Spindle,
Be careful not to allow Woodruff key 4 to be out of position.
It is recommended to apply grease to the key slot on Spindle
in order to hold the Woodruff key securely in place. (Fig. 11)
1) Remove Bearing box from Gear housing. (Fig. 7)
2) Pull off Shoulder pin 7 with pliers while pushing Pin cap with a
finger. (Fig. 12)
Note: Do not pull off shoulder pin 7 without holding pin cap because
Compression spring 7 would sling Pin cap.
Follow the reverse of disassembling steps.
Note: Do not reinstall removed Pin cap because removal of Shoulder
pin 7 damages the inside surface of Pin cap. Be sure to remove
plastic dust of Pin cap from Shoulder pin 7 and to install it onto
a brand-new Pin cap.
