Service Procedure
Tools Required
Pointed Pick, 3/16” and 7/32” Allen Wrenches, and
Needle Nose Pliers
Parts Required
G903-KIT G-Force Valve Plug Kit
Kit Contents: Valve Plug Assy., #222 O-Rings (3), #134 ORing, Dow 112 Grease, Blue Loctite® Mini Dispenser and
Red Loctite® Mini Dispenser
Step 1) Using a pointed pick remove the rubber Port Plug
that retains the ball bearings in the coupling. The port plug
is located on the bottom center of the valve adjacent to the
coupling. Press the pick into the plug and pry out.
Step 5) Holding your thumbs over the detent balls and
springs on the bail handle pull the handle upward and off
using your thumbs to capture the balls and springs when
the handle is removed.
Step 2) Holding the nozzle over a container with the port
plug hole facing down rotate the coupling until all the ball
bearings fall out. 33 balls retain the coupling. Once all the
ball bearings have been removed pull off the coupling,
debris screen, and o-ring.
Step 6) Use your finger to pull out the stainless steel slide
valve. Two or three o-rings seal the slide valve, there will
be some resistance when it is pulled out.
Step 3) Using the 7/32” Allen wrench remove the two button head screws that retain the bail handle to the valve.
These are retained with red Loctite®; some force will be
required for removal.
Step 4) Once the screws have been removed from the
handle, using needle nose pliers remove the cam pin from
each side of the bail handle. These will simply pull out.

Step 7) Inspect the tapered leading edge of the slider.
This is the edge that seals against the plug. If this edge is
damaged replace the slider. (Part # G605)
Step 11) Apply Blue Loctite to the valve plug. Thread the
new valve plug into the valve body until snug. DO NOT
Step 12) Lightly grease the o-rings (VO-222) that are
provided in the kit. Install the o-rings in the valve body in
the grooves where they were removed in Step 8.
Step 13) Place one valve disc in each side of the valve
body from the inside of the valve. Orient the discs as
indicated in the photo.
Step 8) Once the slider has been removed the two valve
discs will come out. (Discs indicated in photo by the red
arrow. Remove them and set aside. Using the pointed pick
remove two o-rings (VO-222) that seal the slide valve.
(Indicated in photo by the red circle) Early versions utilized
two o-rings one; front and one rear. Later versions used
three; one front and two rear. Replace with the appropriate
number of o-rings.
Step 14) Lightly grease the outside circumference of
the slider with the grease provided in the kit. Install the
slider with the chamfered edge facing the valve plug. Use
caution when installing the slider that it does not pull the
valve discs out of place. Push the slider in until it contacts
the valve plug then pull back about 3/8”.
Step 9) Using the 3/16” Allen wrench, un-thread the valve
plug from the valve. The green aluminum center will accept
an Allen wrench.
Step 10) If the old valve plug has a black centering ring,
remove the black ring from the old plug and remove the
white ring from the new plug, place the black ring on to
the new plug. Otherwise, the valve plug can be used as
provided. Using the grease provided in the kit apply a light
coat of grease to the threads of the valve plug.
Step 15) Align the cam pin hole in the valve disc with the
groove in the slider. Insure that the cam pin hole is facing
up nearest the valve detent arc.

Step 16) Install the detent springs and balls back into the
bail handle. Using the same method as when the handle
was removed retain the springs and balls in the handle with
your thumbs. Install the handle over the valve snapping
it into place. Insure that the valve handle is oriented as
indicated in the photo. The cam pin hole should be forward
toward the exit of the nozzle.
Step 17) Install a cam pin in each cam pin hole. Insure it
seats in the groove in the slider. The cam pin face should
be flush with the surrounding handle when properly installed. Apply red Loctite® to the threads of the button
head screws that retain the handle. Install one on each
side of the handle until hand tight.
Step 18) With the valve handle held in the closed position,
using the 3/16” Allen wrench back the valve plug out
(unscrew) unit it makes firm contact with the slider. Once
contact is made with the slider, open the valve handle part
way and unscrew the valve plug 10 degrees. This will set
the proper tension between the valve plug and slider.
Step 19) Included with the kit is a new o-ring (VO-222) to
seal the coupling to valve body connection. Lightly grease
this o-ring. Install this o-ring on the valve body as shown.
Also, lightly grease the ball ring groove on the valve body.
Step 20) Install the debris screen over the valve body
so the concave portion faces down over the valve body.
Next, lightly and evenly press the coupling down onto the
valve body. Pay close attention that the o-ring does not get
pushed out of place or pinched.
Step 21) Install the 33 ball bearings that were removed
from the coupling through the port on the bottom side of
the valve.

Step 22) Lightly grease the port plug then press back into
the valve body. If you have difficulty installing the port plug
a ball bearing may be obstructing the path of the port plug.
Using your pointed pick insure the balls are pushed to
either side of the port plug path. Insure the port plug is
fully seated and flush with the valve body.
Step 23) With the valve in the closed position pour a cup
of water into the valve. Check to insure no water leaks
through. If it does the valve plug likely needs to be backed
out a little further.
