Examine the relay body and head
bores for any damage such as burrs,
nicks, etc. Replace any damaged
pieces.
5.
Replacement seals from a Ruelco
product repair kit are required for
proper relay performance. It is
recommended that all seals be
lubricated before and after
installation with a high quality
silicone base grease.
6.
Install the upper seal into the valve
body. NOTE: This is a cup type seal.
The inside of the cup should be
facing down and toward the valve
body as shown.
7.
Install the head into the upper body.
The panel mount threads should
almost touch the body. If not,
remove the head and verify that
neither the set screws or any debris
are obstructing the correct
installation.
8.
Using the Allen wrench, rotate the
three (3) set screws clockwise until
lightly tightened. Tighten all three (3)
firmly afterwards.
9.
Install the piston seal onto the shaft
subassembly. NOTE: This is a cup
type seal. The inside of the cup
should be facing toward the bottom
of the shaft subassembly as shown.
Be sure that the inside lip of the seal
is completely pushed into the piston
groove.
10.
Lubricate the shaft o-rings and install
on the shaft subassembly.
11.
Lightly lubricate the large bore in the
relay body.
12. Slide the spring over the shaft
subassembly and slide the shaft into
the relay body.
13.
Lubricate the base o-ring (Item 14)
and install into the valve body.
14.
Rotate the base clockwise onto the
body and use the 1” wrench to
tighten.
15.
If a stem protector is to be used,
locate the holes in the protector
body over the threaded holes in the
head. Insert the two (2) screws and
rotate them clockwise to tighten.
16.
Thread the lock nut over the shaft
subassembly until it reaches the last
thread. Do not tighten. Rotate the
knob over the shaft thread until it
touches the lock nut. Hold the knob
and turn the lock nut
counterclockwise with the 7/16”
wrench until firmly tightened.
17.
To install the stem protector washer
and the knob, thread the washer as
far down onto the shaft as possible.
Screw the knob onto the exposed
threads above the washer, but do
not tighten. Pull the relay shaft fully
outward and thread the protector
washer until it stops. NOTE: The
protector seal should now be
completely inside the protector
housing. Release the relay knob and
allow the shaft subassembly to
retract. Rotate the knob clockwise
until it stops. Pull the knob outward
again and use the 7/8” wrench to
turn the protector washer
counterclockwise until tight.
