Inspect and clean the valve body, valve ball, valve stem, and spacers,
removing any dirt or debris. The valve stem and valve body O-ring grooves
must be cleaned before installing new O-rings, to avoid leakage.

their grooves. (See Figure 6-2: “Non-Locking / Locking Valve Stem Assem-
blies,” on page 29.) Also see Figure 6-3: “Installing Non-Locking Valve
Stem” on page 31.
