ASSEMBLING
Do the reverse of the disassembling steps.
Note: Use arbor press and Bearing Setting Plate (of proper size ) when fitting Ball bearing 629LLB
in Gear housing cover. (Fig. 4)
Important: Assemble Gear housing to Motor housing so that Switch lever can be operated with right thumb
as illustrated in Fig. 5.

DISASSEMBLING
1) Remove Bearing box from Gear housing by unscrewing four M4x14 Pan head screws.
2) Remove Retaining ring S-12 and Wave washer 12 from Spindle with Retaining Ring S and R Pliers (No.1R291).
3) Spiral bevel gear 37 can now be removed by hand. Then remove Woodruff key 4. (Fig. 6)
4) Remove Spindle using Gear Extractor, large (No.1R045). Labyrinth ring can now be removed. (Fig. 7)

ASSEMBLING
Do the reverse of the disassembling steps.
Important: Do not to forget to install Labyrinth ring because it is an important part that prevents dust from entering
into Bearing box. (Fig. 9)
How to fit Retaining ring S-12 in place
See Fig. 10.
After installing Spiral bevel gear 37 and Wave washer 12 on Spindle;
1) Put Retaining ring S-12 on Retaining Ring Setting Jig (No.1R343) from the tapered end of the jig.
2) Put the jig onto Spindle, then put Bearing Setting Pipe 20-12.2 (No.1R028) over the jig.
3) Using arbor press, press down the pipe till the retaining ring is securely fitted in place on Spindle with a snap.

1) Remove Bearing box from Gear housing.
2) Pull off Shoulder pin 4 with pliers while pushing Pin cap with
finger. (Fig. 11)
Note: Do not pull off Shoulder pin 4 without holding Pin cap
because Compression spring 8 would sling Pin cap.

ASSEMBLING
Push Shoulder pin 4 through Gear housing and Compression spring 8
into Pin cap.
Note: Do not reuse removed Pin cap because removal of Shoulder
pin 4 damages the inside surface of Pin cap, producing plastic
dust. Therefore, be sure to use a new Pin cap for replacement
and to remove all the plastic dust on Shoulder pin 4.
