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 Replacement”
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 cas-
cade and the wire in the knuckle. Also apply a
small amount of grease into the concentric rings
around the spring.
Install the cascade with the potted side of the cas-
cade towards the outside of the applicator. Make
sure o-ring is in the groove inside the knuckle
labyrinth area.
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 proper 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 connec-
tor 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” hex key
wrench (see “Rear Plate Alignments” 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” hex key 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. Tighten the three (3) rear plate mounting
screws using a 3/16” hex key wrench, 15 lbs•in
torque (1.70 Nm).
