Note in Lubrication:
Gear housing complete of 18-b which has two air holes is used for some countries instead of
six air holes Gear housing of 18-a . The amount of grease required to put in the gear room is
different from 18-a with 18-b as mentioned above.

ASSEMBLING
Assemble by reversing the disassembly procedure.
Note : • Do not forget to put Flat washer 12 in Bearing box. (Refer to Fig. 10.)
• Be careful not to deform Labyrinth ring 19 when assembling to Spindle.
• Referring to Fig. 7, assemble Woodruff key 4, Spiral bevel gear (large) and Wave washer 12 to Spindle.
Then, assemble Retaining ring S-12 using 1R291 by fitting exactly to the groove on Spindle’s drum with snap.
[3] -3. Disassembling/Assembling Shaft Lock Mechanism
(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.
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.
