ACTUATOR
2. Actuator
A: REMOVAL
CAUTION:
•Be careful not to apply excessive load to the
wire cable when adjusting and/or installing;
otherwise, the actuator may be deformed or
damaged.
•Do not bend cable sharply with a radius less
than 100 mm (3.94 in); otherwise, cable may
bend permanently, resulting in poor perfor-
mance.
•When installing cable, be careful not to
sharply bend or pinch the inner cable; other-
wise, the cable may break.
1) Remove clip bands from cruise control cable.
2) Loosen nut which secures cruise control cable
end to throttle cam and then remove cable from
throttle cam.
3) Remove actuator attaching bolts.
4) Remove actuator while disconnecting connec-
tor.
B: INSTALLATION
Install in the reverse order of removal.
Tightening torque:
7.4 N·m (0.75 kgf-m, 5.4 ft-lb)
NOTE:
(A): Must be adjusted when cable end outer is fixed
in place, so that gap between throttle cam and lever
is 0 —1 mm (0 —0.04 in).
(Must be attached while throttle cam is being pulled
by wire cable.)
(B): Must be coated evenly on cam end inner con-
nection.
(C): Cover must be inserted securely, until tip of ca-
ble touches cover stopper.
C: INSPECTION
Measure resistance between cruise control actua-
tor terminals.
If NG, replace cruise control actuator.
