the motor holder to the motor holder.
3) Apply grease (1/2 drop) between the worm shaft gear and gear
tooth.
4) While the worm gear is engaged with the worm shaft gear,
insert the worm shaft tip into the groove B and fix the worm
shaft under the claw E.
5) While aligning the chassis's two square holes with the two round
holes, attach the motor holder block assy with the screw (M1.4
× 2.5) 1.
