[3] -2. Disassembling/ Assembling Gear Section and SJS (Clutch) Mechanism

1) Apply Makita grease SG. No.0 to the spring when assembling Lock spring 24 to Spiral bevel gear 57.

2) Tilt and place Lock spring 24 on Spiral bevel gear 57. Press down the portion A (the highest portion) of the spring

using arbor press. While turning the gear counterclockwise, press down the portions B, C, D sequentially.

After one turn of of the gear, the top surface of the spring will be almost flat. Lock spring 24 can now be fit on

Spiral bevel gear 57 by pressing down the entire top surface of the spring. (Fig. 5)

3) Assemble Lock sleeve to Spiral bevel gear 57 by doing the same way as you did to install Lock spring 24. (Fig. 6)

4) Do the reverse of the disassembling steps.

[3] -3. Replacing Armature

1) Separate Base and Wheel cover. (Refer to [3] -1. of page 2.)

2) Remove Brush holder cap and Carbon brush. Separate the Gear housing section from Motor housing by unscrewing

four M5x40 Hex bolts.

3) Armature can now be removed from Gear housing by tapping the end surface of Gear housing with plastic hammer.

Ball bearing 6202DDW still remains in Gear housing in this step.

4) In order to remove Ball bearing 6202DDW;

Remove Retaining ring R-40 and Flat washer 30. Insert the removed Armature lightly into the ball bearing again.

While swaying the commutator end of the armature, pull out the ball bearing with the inserted armature. (Fig. 7)

5) Tighten four M5x40 Hex bolts to the recommended torque of 7.4 - 15Nm when fastening the Gear housing section to

Motor housing.
