9. Lubricate and install the o-ring(30) onto the adjustment stem(29).
10. Holding the adjustment stem(29) vertically, install the adjustment
spring(27) over the stem so it rests in the concave end of the
follower(28), then place the spring pad(26) on top with the small
rounded end in the spring (Fig. 13).
11. Holding the housing(4) with the adjustment tube(24) facing down
and your index finger inside pressing the tube against the inner
wall of the housing, insert the adjustment stem(29), spring(27)
and spring pad(26) up into the tube. (Fig. 14). This will push
the balance shaft(21) partially out the other end of the tube and
up against the poppet. Ensure that the balance shaft is properly
aligned with the poppet. Spring tension will hold parts in place.
12. Install the thrust washer(31) onto the adjustment stem(29), then
slide the packing nut(32) over the stem and thread it onto the
adjustment tube(24) until secure. Tighten with a 5/8" open end
wrench to a torque of 12 in/lbs.
CAUTION: DO NOT over tighten! Doing so will damage the
housing or other parts, requiring their replacement.
13. Install the adjustment knob(33) over the adjustment stem(29)
and packing nut(32). Insert the adjustment knob cap screw(7)
and tighten with a 3/32" hex key to a torque of 4 in/lbs.
14. Using a poppet installation tool, push the poppet(15) into the
housing to expose the washer(18) and spacer(19) inside the
housing. Place the forks of the lever arm(17) over the poppet
shaft between the washer and the spacer. Relax the poppet and
watch to ensure that the lever arm stands upright.
15. Lubricate and install the o-ring(13) onto the inlet coupling(12).
Install the coupling into the inlet tube of the housing(4) with the
smaller opening facing in. Tighten clockwise with a 3/4" open
end wrench to a torque of 110 in/lbs.
16. Lubricate and install the o-ring(10) onto the orifice(11). Lubricate
the threads of the orifice with a very thin film of lubricant and insert
the orifice into the inlet coupling(12) with the knife edge facing
in. (Fig. 15)
CAUTION: Be careful to protect the delicate knife edge as
this is done.
NOTE: For best sensitivity of touch during Step #17, place
your forefinger gently on the locknut while slowly turning
the orifice. As soon as contact is made, you will feel the
locknut begin to turn. Hold the screwdriver by the shaft
rather than the handle.
