Description
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(Figure 1). The springs are seated on a steel washer on the cylinder head with
retainers and locks retaining the springs (Figure 2). The springs are installed with the smaller diameter against spring retainer (Figure 1).
