not remove nut 6 from shaft 5Fig.22.
3.While firmly holding spring housing 7

boss 8 is engaged with the next notch on
the housing. Turn the housing anticlockwise
to increase and clockwise to decrease spring
tension. Then tighten nut 6 Fig.23 to hold
the housing in place.

Nut 6 Fig. 23 should not contact spring
housing 7 when tight.
