Rear Valve Manifold Removal
Cascade Removal / Replacement
Removal
Remove all components, shroud, break-away
ring, rear plate, and rear manifold. (See “Rear
Plate/Rear Manifold/Cascade Removal Re-
placement” in the “Maintenance” section.)
Pull the cascade straight out of the knuckle.
Replacement
Use a small amount of dielectric grease
(LSCH0009) on the end of the spring of the
cascade and the wire in the knuckle. Also ap-
ply a small amount of grease into the concen-
tric rings around the spring.
Install the cascade with the potted side of the
cascade towards the outside of the applicator.
Cascade Removal
By hand, attach the rear plate to the rear valve
manifold using the three (3) mounting screws.
Do not fully tighten. The rear plate is designed
such that it mounts to the rear valve manifold
only one way. Pull the assembly into the prop-
er position based on the position of the single
air tube and the single hole for the air tube in
the rear valve manifold. Pull the coiled tube
fitting and ferrules into the port for fluid and
tighten clockwise into place. Hand tighten until
stop, then tighten 1/2-3/4 turn with a wrench.
Attach the cup wash fitting and ferrule in the
cup was port and tighten into place. Hand
tighten until stop, then tighten 1/8-1/4 turn
more with a wrench. Push the Cascade con-
nector into the hole in the rear plate for it.
Align the timing mark on the plate with the
timing mark on the connector using a
3/32”Allen wrench (see “Rear Plate Align-
ments” figure).
Rear Plate Alignments
Tighten the set screw in place. Tighten to 10
lbs•in (1.13 Nm) torque. Align the flat of the
fiber optic cable perpendicular to the set
screw. Tighten the set screw with a 3/16” Al-
len wrench. Tighten to 10 lbs•in (1.13 Nm)
torque. Install the five (5) air bolts by hand.
Tighten each bolt in a circular pattern. Tight-
en the three (3) rear plate mounting screws
using a 3/16” Allen wrench, 15 lbs•in torque
(1.70 Nm).
