(25 MM) PORT FITTING IN
ITS PLACE. REFIT THE TOP COVER & DIVERTER
A S S E M B LY WITH THE DIVERTER POSITIONED
NEAR THE DISCHARGE PORTS AND SECURE IT IN
PLACE WITH THE THREE MACHINE SCREWS.
The valve should be secured to a solid mounting surface.
After selecting an appropriate mounting position, hold
the valve in place and mark the location of the three
mounting holes in the valve base. Drill appropriate size
holes for the fasteners being used and attach the valve
to the mounting surface. Rotate the discharge ports to
orient them in the desired direction that best accommodates
the plumbing. Attach each waste hose to the appropriate
valve port and secure each connection with two
stainless steel band clamps.
The valve may also be mounted in a through bulkhead
configuration with just the selector handle being
exposed on the operational side of the bulkhead. To
install this way, an optional 45500-1000 Handle
Extension Kit is required. Remove the handle retention
screw and handle from the diverter shaft. Position the
valve in its desired mounting location and mark the position
of the diverter shaft. Bore a 1-5/8
"
(40 mm) hole through
the bulkhead at the position marked for the diverter
shaft. Push the 45500-0000 Handle Extension onto the
diverter shaft. Reposition the valve assembly in its
mounting location with the shaft extension centered in
the 1-5/8
"
(40 mm) hole and mark the location of the
three mounting holes in the valve top cover plate on the
bulkhead. Drill holes for the mounting fasteners at each
of the three marked locations and attach the valve via its
top plate to the bulkhead. Fit the handle to the handle
extension and secure the handle and handle extension to
the Diverter shaft with the long screw provided in the
Handle Extension Kit. Rotate each port to the desired
position and attach each hose securing them with two
stainless steel band clamps on each port.
Mounted through bulkhead
with optional handle extension.
Mounted on bulkhead.
SERVICE
The Y- Valve is designed to be self cleaning as the diverter
is moved from one port position to the other. Therefore,
it is recommended that the valve be operated periodically
(about once per month) to prevent debris from
accumulating on the sealing surfaces. Other than this
periodic operation, there is no regular service required
unless the valve stops functioning properly.
Should the valve ever develop a leak or show signs of
leakage past the diverter allowing liquid into the port that
is intended to be closed, the valve should be serviced
with a service kit number 45488-0000. This kit includes all
Y- Va l v e O-Ring seals and a molded rubber diverter seal.
Flush and drain the plumbing system in which the
Y- Valve is installed. If connected to an overboard
through hull and seacock, close the discharge seacock.
It may be easier to remove the entire Y-Valve assembly
so it can be serviced on a workbench but it is not
required, unless the valve is installed in a through bulk-
head configuration. Remove the three screws that retain
the valve cover to the body. Lift the top cover, handle and
diverter assembly off and out of the body.
Note: There are three pockets on the underside of the
cover near each cover screw where the blade of a
screwdriver can be inserted to gently pry the cover
upward to begin the separation process.
Unscrew the handle retention screw and remove the
handle from the diverter. Pull the diverter from the top
cover. Pull each port fitting from the body port pockets.
Remove the O-Ring seals from each port fitting. Remove
the top cover O-Ring seal from its locator ring on the
cover. The diverter shaft O-Ring seal will likely remain in
the O-Ring bore in the top cover but may also stick to the
diverter shaft. Remove the diverter shaft O-Ring seal.
Remove the two screws that retain the diverter seal
retainer plate to the diverter. Remove the seal retainer
plate and molded rubber diverter seal. Clean all parts,
especially each O-Ring groove and diverter shaft O-Ring
bore in the top cover. Also clean the diverter shaft where
it contacts its O-Ring seal and the diverter pivot pin at
the bottom of the valve body and pivot pin socket in the
diverter. Take care while cleaning not to scratch any of
the sealing surfaces.
Position the new molded rubber diverter seal in the frame
of the diverter face. Place the diverter seal retainer plate
in the center of the diverter seal and secure it in place
with the two plate retainer screws. Install new top cover
O-Ring on its locator ring on the top cover and port
O-Rings on each port. Position the diverter shaft O-Ring
in its bore in the top cover. Lubricate all O-Rings, the
diverter seal and the diverter shaft pivot pin on the
bottom of the diverter with a small amount of grease or
petroleum jelly. Slide each port with installed O-Ring into
its respective socket in the valve body. Slide the diverter
shaft into the center hole of the top cover, through the
O-Ring seal, with the diverter positioned opposite the
raised molded-in handle stop on the underside of the top
Max.
