STEP 16-Adjusting the Linkage System
(Tools required–One tape measure or scale, one 3/4” wrench one
5/8” wrench and a torque wrench.)
1. Align the front linkage assembly (as shown in figure 2-18)
parallel to the frame. (See figure 3-45.)
2. With the front linkage assembly parallel to the frame, verify
that the foot plates are level with one another and are
between 7.50” and 7.75” to the center line of the pivot shaft
of the foot pedal from the floor. (See figure 3-46.)
3a. If the foot plates are not level or between 7.50” and 7.75”
from the floor go to step 4.
3b. If the foot plate are level and between 7.50” and 7.75” from
the floor go to step 5.
4. To adjust the position of the foot plate rotate the long tie rod.
(See figure 3-47.) Note that one full revolution (360 degrees)
of the tie rod is equal to approximately 1” of movement at
the foot plate.
5. Verify that the idler pulley does not make contact with either
the frame or the alternator during operation. If the idler
makes contact with either one, the unit is not properly
adjusted. Repeat steps 1 through 4.
6. Once the linkage system is properly adjusted the two 1/2-28
check nuts must be tightened to a 50 ft-lb minimum using a
torque wrench. (See figure 3-45.)
