2-37.1. WATER MANIFOLD ASSEMBLY (CONT)
ADJUSTMENT
NOTE
Ball valve crank (31) and anchor
bracket (27) must be exactly in line.
The air actuator must not be slanted
or cocked with relation to the plane
of
crank
movement.
Binding
between
the
crank
and
anchor
bracket
will
occur
if
they
are
misaligned.
1.
Check clearance after piping the machine.
Maintain 1/16" ±1/32" clearance between the open and
closed crank stop (30) positions to prevent valve stem
damage when closed and ball overtravel when opened.
NOTE
Overtravel will cause the valve to
throttle the flow of incoming water.
This has a detrimental effect on valve
life and also increases filling time.
2.
To adjust both the alignment and clearance,
loosen the anchor bracket (27) and perform the following
as needed:
a.
Rotate the anchor bracket (27) around the
pipe (2) to adjust alignment.
b.
Slide the anchor bracket (27) up or down
the pipe (2) to adjust clearance.
3.
Adjust the needle valve (32) (if equipped) to
slow the opening and closing of the air actuated ball
valve assembly. One quarter to one half turn is normal.
4.
Ensure
that
all
air
actuated
ball
valve
assemblies close at the same speed.
NOTE
FOLLOW-ON MAINTENANCE:
Water heater installed (TM 10-3510-209-10).
