Astuator Replacement
1.Pull back the boot, and loosen the locknut. Then dis-
connect the cable from the bracket.
Disconnect the cable end from the actuator rod.
Disconnect the 4P connector from the actuator.
Disconnect the vacuum hosa from the vacuum tank.Pull out the vent hose.
Remove the three mounting bolts and the actuator
with the bracket.
CABTI aP CONNECTOR
lf necessary, disconnect the cable end from the link-age over the accelerator pedal, then turn the grom-
met 90' in the bulkhead, and remove the cable,
Install in the revers€ order of removal, and adjust
free play at the actuator rod after connecting thecable (see ne)d column).

Actuator Cable Adjustment
Check that the actuator cable operates smoothlywith no binding or sticking.
Stan the engine. Hold the engine at 3,000 rpm withno load (Afl'in N or E, M/T in neutral) untit theradiator fan comes on, then let it idle.
Measure the amount of movement of the actuato.rod until the cable pulls on the accelerator lever(engine speed starts to increase). Free Dlay shouldbe 11 t 1.0 mm (0.43 I 0.04 in).
LOCKNUT FREE PLAY: 11 1 1.0 mm
{o.i|:l r 0.oit in}
lf free play is not within specs, loosen the locknut,
and turn the adjusting nut as required.
NOTE: lf necessary. check the throttle cable freeplay (see section 11). then recheck the actuator rodfree play.
Retighten the locknut, and recheck the free play.

Connectors - "C"
The cavities (and wire terminals) in each
connector are numbered starting from the
upper left, looking at the male terminals trom
the terminal side (or looking at the female
lerminals f rom the wire side. Both views are in
the same direction so the numbers are the
same.) All actual cavities are numbered, even
if they have no wire terminals in them.
