Assembly of the Shutoff Valve (for 6WT or 6WRT)
1. Using a wooden dowel, push the Shutoff Valve Stop
(25) to the bottom of the Shutoff Valve opening.
2. Install the Regulator Body Seal (32) in the groove
near the bushing inside the Shutoff Valve opening.
Make certain the Shutoff Valve Spring (26) seats in
the Shutoff Valve (24) recess.
3. Insert the Shutoff Valve Spring and the Shutoff Valve
into the Motor Housing (1).
4. Screw the Regulator Body (27) into the Housing and
tighten it to 12 to 15 ft–lb (16 to 20 Nm) torque.
Assembly of the Reverse Valve (for 6WRS or
6WRT)
1. For 6WRS, install the Reverse Valve Bushing Seal
(3A).
2. Insert the Reverse Valve Lock Pin (21) into the hole
in the side of the Reverse Valve (19).
3. Slip the Reverse Valve Spring (23) into the end of the
Reverse Valve opposite the Reverse Valve knob.
If the Reverse Valve comes out of the Housing, the
Lock Pin did not enter the L–shaped slot.
4. Holding the Reverse Valve with the Lock Pin upward,
align the L–shaped slot inside the reverse valve
bushing with the Lock Pin. Slide the Reverse Valve
into the bushing until the Reverse Valve Spring is
partially compressed. Rotate the assembled Housing
and Valve one–half turn (180
°
) and tap the Housing
opposite the Lock Pin with a plastic hammer until the
Lock Pin drops into the L–shaped slot. Slowly
release the Reverse Valve.
5. Install the Lock Pin Retainer (20) and Retainer
Setscrew (22) in the end of the Reverse Valve. The
Setscrew must not protrude from the Reverse Valve.
6. Operate the Reverse Valve to make certain it
functions properly.
Assembly of the Motor and Throttle
1. If the Throttle Plunger Bushing (2) was removed,
proceed as follows:
a. Insert the Throttle Plunger Bushing into the Motor
Housing (1) to a depth approximately one–half the
length of the Bushing.
b. Put a few drops of Permabond

* sealant in the
counterbore surrounding the outside diameter of
the Bushing.
c. Rotate the Bushing approximately 180
°
to make
certain the sealant makes complete contact around
the outside of the Bushing.
d. Push the Bushing into the Housing until it bottoms
against the shoulder inside the Housing.
e. Allow the sealant to cure for eight hours at room
temperature.
2. Carefully grasp the flats on the Motor Housing (1) in
leather–covered or copper–covered vise jaws, inlet
end facing upward.
3. If the Throttle Valve Seat (8) and Throttle Valve Seat
Support (9) were removed, use a flat–faced rod 1/2”
(12.7 mm) in diameter by 3” (76 mm) long to push
the Seat Support into the Motor Housing until it seats.
Use the same rod to push the Valve Seat into the
Housing until it seats against the Seat Support.
4. Install the Throttle Plunger Seal (7) in the groove of
the Throttle Plunger (6).
5. Insert the Throttle Plunger into the Plunger Bushing
and rotate the Plunger until the hole in the Plunger
aligns dead center with the hole in the Throttle Valve
Seat.
