* Use existing piston on valves with honed bore. See caution note on page 12.
The parts kit contains two different gaskets for the pilot valve.
Which ones are used depends on the pilot valve design.
The Tetraseal, part #641-6 is a flexible gasket and is used on
design “AA” valves. These valves can be identified by the
square groove on the bottom of the pilot valve.
The bottom of the pilot valve on the design “BB” valve is
machined flat to accommodate the metal “Wolverine” gasket
part #14000-5.
