(3) Measure the distance between the center of the
lever ball and the rear face of the cable mounting
bracket (Fig. 9). Dimension should be 126.5 mm (5.0
inches.) If not, proceed to following step.
(4) To prevent damage to ends of linkage, attach
locking-type pliers to the flat (Fig. 7) located on the
linkage rod before loosening locknuts.
(5) Loosen the right-hand-threaded nut (Fig. 7).
(6) Loosen the left-hand-threaded nut (Fig. 7).
(7) Rotate the flat on the linkage rod (lengthen or
shorten) to achieve proper linkage adjustment (Fig.
9). 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 ac­
celerator pedal is pressed to the floor. This is checked
by observing throttle lever breakover position. Pro­
ceed to the following:
(a) Key OFF and engine OFF for this test.
(b) Two people are needed for this test. From in­
side 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 (Fig. 7) should be observed.
(c) Continue to press the accelerator pedal to the
floor. If throttle lever breakover is operating cor­
rectly, 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 auto­
matic transmission: A throttle' position sensor
(TPS) is used with this driveline combination. TPS
voltage must now be tested. Refer to Throttle Posi­
tion Sensor. This can be found in the Diesel Engine—
Component Removal/Installation section of this
group.
