6.4 RATCHET LEVER MOUNTING
a. Position the disc in the closed position.
b. Install the ratchet notch plate using machine bolts, nuts and lock washers, but do not tighten the
fasteners.
c. Install the drive key in the shaft (where applicable). Tap the key into place to ensure it is fully seated in
the keyway.
d. Install the handle so that it is parallel with the disc face. The locking lever must be fully retracted
before it will pass through the ratchet plate. Tighten the set screw in the handle against the key.
e. With the handle installed flush with the ratchet plate, engage the locking lever with the ratchet plate.
Using the handle, adjust the position of the ratchet plate until the disc face is parallel with the valve
face, then tighten the fasteners securely.
6.5 GEARBOX MOUNTING
a. Position the disc in the closed position.
b. Install the drive key in the shaft (where applicable). Tap the key into place to ensure it is fully seated.
c. Rotate the gear shaft to the full clockwise position. Align the keyway in the gearbox bore with the key
in the shaft and slide the gearbox onto the shaft.
d. Fasten the gearbox to the mounting bracket with the appropriate machine bolts and lock washers. It
may be necessary to rotate the gear shaft slightly to align the mounting holes in the gear with the
plate.
e. Adjust the stops in the gearbox to position the face of the disc parallel with the face of the valve in the
closed position and perpendicular to the face of the valve in the open position.
