Drain Valve

WARNING

INJECTION HAZARD

To reduce the risk of serious injury,
whenever you are instructed to relieve
pressure, follow the

Pressure Relief

Procedure

on page 12.

43a

43b

Apply thread sealant

Handle shown
in closed position

Apply grease
to face of base

Torque into pump
manifold to 140 in–lb
(16 N.m)

43c

Fig. 11

43h

43d

43e

43g

Turn the handle (46) to the closed position. Drive
out the pin (45). Remove the handle.

Remove the base (44).

Unscrew the drain valve (43). The gasket (43a)
and seat (43b) will stay in the valve.

Repair

Unscrew the spring retainer (43h) from the valve
body. Remove the spring, washers and stem/ball.
Clean any debris from the ball or seat area.

If replacing the gasket (43a) or seat (43b), pry out
the gasket.

NOTE:

Whenever the gasket (43a) is removed, re-

place it with a new one.

Coat the o-ring (43d) with grease. Press the stem
into the valve body. Install the spring, washers and
spring retainer into the valve body.

Place the seat (43b) in the valve body so the
lapped side is toward the ball. Apply a small
amount of grease to the new gasket (43a) 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

Apply a small amount of thread sealant onto the
valve (43) threads. Tighten the valve into the pump
manifold to 185 in–lb (21 N.m).

Lightly grease the face of the base (44) and install
the base. Turn the stem so the pin hole is vertical.

Securely install the handle (46) and drive pin (45).

WARNING

INJECTION HAZARD

To reduce the risk of serious injury, keep
the drain valve clean. Check drain valve
operation before spraying.
