3. Position the eccentric plug so the switch pin is
offset toward the control mounting surface. This
will provide the best contact between the pin and
the cam on the control shaft.
4. Hold the control shaft in its “neutral” position (in
the center of the control shaft “free-play” area).
Locate the switch pin in the slot of the switch cam
by turning the eccentric plug while checking the
pin position (depth) in the plug. When the pin
engages the cam slot, the pin will be at its maxi-
mum depth in the plug. Hand tighten the plug lock
nut to hold the eccentric plug in position.
5. Turn the control shaft an equal amount in either
direction from “neutral.” The switch pin should
move out of the eccentric plug an equal distance
when the control shaft is turned. Turn the eccen-
tric plug to center the switch pin with the cam slot.
Only a small amount of adjustment in either direc-
tion should be needed to center the pin.
6. While holding the eccentric plug in place, tighten
the eccentric plug lock nut to 27 Nm (20 ft•lbf).
Reinstall and adjust the switch as outlined in the
previous section.
NOTE: The eccentric plug normally requires
between 5-1/2 and 6-1/2 turns to install into the
control housing .
CAUTION
Do not turn the eccentric plug into or out of the
housing beyond specifications.
7. Once the switch is correctly adjusted, hold the
switch in place and tighten the locknut to 27 Nm
(20 ft•lbf) torque.
