nipple with its O-ring into the regulator body. Using
the torque wrench, tighten the inlet nipple to 40 inch
pounds.

piston, spring set and spacer into the adjustment tube
of the regulator body, as shown in the blow-apart
drawing.
10) Lightly lubricate the new O-ring then install the
new washer and O-ring on the adjustment shaft.
11) Slide the packing nut onto the adjustment shaft,
then slip the knob onto the end of the shaft. Hold the
shaft and rotate the knob until the pinholes line up.
Use the inlet valve holder - the “L” shaped tool (or a
3/32” punch), from the regulator tool kit to accurately
align these holes.
12) Install the retaining pin by tapping it in with a
small hammer until it is flush with the outer surface
of the knob.
13) Lightly lubricate the end of the shaft and the
threads with the appropriate lubricant, and then thread
the adjustment shaft clockwise, using the adjustment
knob, into the regulator tube until the packing nut
can be started.
Back out the adjustment knob once the packing nut is
engaged on the demand regulator body to access the
packing nut with the torque wrench. Using a torque
wrench, tighten the packing nut to 40 inch pounds.
