In accordance with instructions in Service Manual Section 6C, when performing service on accelerator controls, inspect the linkage and cables for
binding, interference with other components or physical damage (kinks, burns, etc.):
-
Grasp accelerator cable terminal, and move it in and out. Cable should move freely with no binding or sticking.
-
Pull cable out and release the terminal. Due to pedal weight, the cable should return to its fully retracted position without delay.
-
If required, replace cable per Service Manual Section 6C.
14.
Install the throttle valve (T.V.), cruise control, and accelerator cables.
15.
Adjust T.V. cable and cruise control cable, per the procedures in Service Manual Sections 7A and 9B, respectively.
16.
Check linkage operation prior to starting engine by actuating accelerator pedal several times throughout its full range:
With the aid of an underhood observer or diagnostic scanner such as a Tech 1, check to ensure that the throttle lever reaches full "wide-open"
upon fully depressing the pedal and that it returns to the idle position without delay upon releasing the pedal.
Throttle should operate smoothly with no binding or sticking. Pedal operating efforts required to reach full throttle should not be excessive.
If operation is unsatisfactory, repair or replace other linkage components (pedal, cables, etc.) as required, per the Service Manual procedures.
NOTICE:
Do not attempt to use lubricant on cables, internal damage may result. Unsatisfactory operation is to be corrected by cable replacement
only.
