Throttle Valve Cable/Linkage: Adjustments
Throttle Cable Attachment At Engine
The transmission throttle valve is operated by a cam on the throttle lever. The throttle lever is operated by an adjustable cable. The cable is
attached to an arm mounted on the throttle lever shaft. A retaining clip at the engine-end of the cable is removed to provide for cable adjustment.
The retaining clip is then installed back onto the throttle valve cable to lock in the adjustment.
A correctly adjusted throttle valve cable will cause the throttle lever on the transmission to move simultaneously with the throttle body lever from
the idle position. Proper adjustment will allow simultaneous movement without causing the transmission throttle lever to either move ahead of, or
lag behind the lever on the throttle body.
Checking Throttle Valve Cable Adjustment
1. Turn ignition key to OFF position.
2. Remove air cleaner.
Throttle Cable Attachment At Transmission
3. Verify that lever on throttle body is at curb idle position. Then verify that transmission throttle lever is also at idle (fully forward) position.
4. Slide cable off attachment stud on throttle body lever.
5. Compare position of cable end to attachment stud on throttle body lever:
-
Cable end and attachment stud should be aligned (or centered on one another) to within 1 mm (0.039 inch) in either direction.
-
If cable end and attachment stud are misaligned (off center), cable will have to be adjusted as described in Throttle Valve Cable Adjustment
procedure.
6. Reconnect cable end to attachment stud. Then with aid of a helper, observe movement of transmission throttle lever and lever on throttle body.
-
If both levers move simultaneously from idle to half-throttle and back to idle position, adjustment is correct.
-
If transmission throttle lever moves ahead of, or lags behind throttle body lever, cable adjustment will be necessary. Or, if throttle body lever
prevents transmission lever from returning to closed position, cable adjustment will be necessary.
Throttle Valve Cable Adjustment Procedure
1. Turn ignition switch to OFF position.
2. Remove air cleaner if necessary.
3. Disconnect cable end from attachment stud.
Carefully slide cable off stud. Do not pry or pull cable off.
4. Verify that transmission throttle lever is in fully closed position. Then be sure lever on throttle body is at curb idle position.
5. Insert a small screwdriver under edge of retaining clip and remove retaining clip.
6. Center cable end on attachment stud to within 1 mm (0.039 inch).
