3500 4x2 Pickup L6-359 5.9L DSL Turbo (1994)
Linkage Measurement
3. Measure the distance between the center of the lever ball and the rear face of the cable mounting bracket. Dimension should be 126.5 mm (5.0
inches.). If not, proceed with the following.
4. To prevent damage to ends of linkage, attach locking-type pliers to the flat located on the linkage rod before loosening locknuts.
5. Loosen the right-hand-threaded nut.
6. Loosen the left-hand-threaded nut.
7. Rotate the flat on the linkage rod (lengthen or shorten) to achieve proper linkage adjustment. Tighten both nuts after adjustment.
8. With the engine OFF, operate the throttle from accelerator pedal and check for throttle lever action and binding. Be sure throttle lever stop is
against the low idle speed screw after throttle is released.
9. Be sure of wide open throttle (WOT) when accelerator pedal is pressed to the floor. This is checked by observing throttle lever breakover position.
Proceed to the following:
a. Key OFF and engine OFF for this test.
b. Two people are needed for this test. From inside of the vehicle, press the accelerator pedal about half-way to the floor. Movement of both the
throttle lever and throttle lever-to-injection pump lever linkage rod should be observed.
c. Continue to press the accelerator pedal to the floor. If throttle lever breakover is operating correctly, the throttle lever-to-injection pump lever
linkage rod should have stopped moving while the throttle lever continues to move towards the rear of vehicle.
10. Again, check and verify low idle speed. Adjust if necessary
11. Diesel engines equipped with an automatic transmission: A Throttle Position Sensor (TPS) is used with this driveline combination. TPS voltage
must now be tested. Refer to Throttle Position Sensor.
