[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.
