Put a few drops of light oil around the inner surface of
the tool. This component of the tool may require grinding to
enable it to clear the edge of the square tube valve lifter.
h. Place the new seal on the longer tool. With the seal lips toward
the spray bar, push the tool down inside the shorter tool until the
seal is seated.
i. Pull out both tool components.
j. Install the new O-ring on top of the seal.
k. Replace the washer on top of the O-ring.
l. Replace the snap ring. MAKE SURE the ring is firmly snapped into
the groove.
m. Coat the valve stem assembly with light oil and reinstall it through
the hole in the bottom of the spray bar.
n. Replace the lifting finger.
o. Align a flat side of the locking nut parallel with the edge of the
square tube valve lifter and tighten the locking nut.
p. Clean the seat bushing and washer and o-ring. Coat the threads
with No. 1 Permatex gasket cement.
q. Reinstall the seat bushing. Tighten it to 15 ft lbs. Of torque. Avoid
distorting the seat.
NOTE: Do not guess at the proper torque! Use a torque wrench.
Adjust Actuators for Spray Nozzle Valves (Mechanical Linkage)
This adjustment is for the optional mechanical linkage and does not apply
to the Tri-Valves. This adjustment is set at the factory. It should not be
changed in the field unless a linkage has been damaged so that the
affected valves do not close properly.
a. Inspect the valve assemblies and make sure they are clean and
free of obstructions between seat and ball.
b. Make sure the switch controlling the affected valve is OFF.
Inspect the pneumatic cylinder and verify that the actuator rod is
fully extended (approximately 1 inch).
c. Examine the center valve of the affected set. The valve stem
should show 1/16” remaining travel when pushed down. Use a
dial indicator to measure the distance if one is available.
