DISASSEMBLING
Follow the reverse of disassembling steps.
Note: When installing the larger Spiral bevel gear 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

1) Remove Bearing box from Gear housing. (Fig. 7)
2) Pull off Shoulder pin 7 with pliers while pushing Pin cap with a

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.
