5.2 Valves and Seats. Replace badly worn or grooved valves and seats. If

either the valve or the seat is worn, replace both as they are matched parts.

Ensure that the valve and seat are clean before installation. Foreign matter

will interfere with proper seating.

5.3 Levers. Levers and linkages wear at pivot points. If excessive play in

the linkages is found, they should be replaced. Worn levers affect the bucket

or float travel and result in a loss of capacity. Replace corroded or worn

pins.

5.4 Buckets and Floats. Replace corroded or damaged buckets or floats.
