VALVE SPRINGS
DESCRIPTION
There are two interchangeable, floating (spring rotates during operation), valve spring designs. Type A may be identified by the counterclockwise
(spring spirals down and to the left) appearance, And Type B may be identified by the clockwise (spring spirals down and to the right) appearance.
Both of the valve springs are a bee-hive shaped design but have different specifications (Fig. 18). The springs are seated on a steel washer on the
cylinder head with retainers and locks retaining the springs (Fig. 19). The springs are installed with the smaller diameter against spring retainer (Fig.
