tighten the castle nut (2) until a slight resistance in the wheel
rotation is felt.

vertical - is aligned with the cotter pin hole in the shaft.

Fit a new cotter pin (9) and bend it over the end of the axle.

Fill the hub cap with fresh grease and screw it on to the hub
again.
Repeat the procedure on LH hub assembly.
