Note 1: Ball bearing 6202DDW is damaged whenever Large spiral bevel gear is removed from Spindle.
Be sure to replace the Ball bearing with new one.

Note 3: Use 1R036, 1R030 and arbor press when assembling Large spiral bevel gear to Spindle. (Fig. 18)
Note 1: Ring spring 7 inevitably loses its elasticity when removed from Spindle. This will also happen to new one when
it is assembled to Spindle. Therefore, reuse removed Ring spring 7 if it is not damaged.
Do not forget to fasten Ring spring 7 securely to Spindle using pliers whether it is removed one or new one.
Note 2: Do as described in Fig. 19 when assembling Lock spring 16 and Lock sleeve to Large spiral bevel gear.
