Repair

1. Unscrew the spring retainer from the valve body.

Remove the spring, washers and stem/ball. Clean
any debris from the ball or seat area.

2. If replacing the gasket (42a) or seat (42b), pry out

the gasket.

NOTE:

Whenever the gasket (42a) is removed, re-

place it with a new one.

1. Coat the o–ring (42d) with grease. Press the stem

(42c) into the valve body. Install the spring, wash-
ers and spring retainer into the valve body.

2. Place the seat (42b) in the valve body so the

lapped side is toward the ball. Apply a small
amount of grease to the new gasket (42a) and in-
stall it in the valve body.

NOTE:

The gasket will protrude from the end of the

valve until the valve is tightened into pump, which cor-
rectly seats the gasket.

Replacement

1. Apply a small amount of thread sealant (42e) onto

the valve (42) threads. Tighten the valve into the
pump manifold to 185 in–lb (21 N.m).

2. Lightly grease the face of the base (43) and install

the base. Turn the stem so the pin hole is vertical.

3. Securely install the handle (45) and drive the pin

(44).
