1. Turn the handle (45) to the closed position. Drive
out the pin (44). Remove the handle.

(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 stemlball. 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, wash-
ers 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 cor-
rectly seats the gasket.
Replacement

of
thread sealant (42e) onto
the valve (42) threads. Tighten the valve into the
pump manifold to 185 in-lb (21 Nm).
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).
