1. Turn the handle (45) to the closed position. Drive

out the pin (44). Remove the handle.

2. Remove the base (43).

3. Unscrew the drain valve (42). The gasket (42a)

and seat (42b) will stay in the valve.

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.

3. Coat the o-ring (42d) with grease. Press the stem

into the valve body. Install the spring, washers and

spring retainer into the valve body.

4. 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

install it in the valve body.

NOTE: The gasket will protrude from the end of the

valve until the valve is tightened into pump, which

correctly 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 pin (44).
