Procedure "C"

Figure 6:

1. Raise the rear of the truck with body jacks to attain a clearance of 6-5/8" between the bottom surface of each rubber jounce bumper and the rear axle tube, Figure 6.

Figure 7:

2. Remove the nut from the valve shaft and remove the leading arm of the linkage assembly, Figure 7. Save the nut.

3. Remove the bushing and clip from the leading arm of the linkage assembly.

4. Install the new bushing and clip provided in the linkage kit, (E8TZ-2L193-A) Figure 7.

Figure 8:

Figure 9:

5. Rotate the valve shaft one (1) full turn in either direction. Position the shaft with the flat at the bottom and parallel with the ground, Figure 8.

6. Install the indexing tool, (T90T-2588-A) on the shaft so the flat on the tool aligns with the flat on the valve shaft. Make sure the valve shaft is nested fully in the tool opening and that the upper surface of the tool rests on the valve body, Figures 8 and 9.

7. Make sure the tool and valve shaft are firmly engaged. Rotate the indexing tool counter-clockwise until the edge surface of the tool contacts the brake hose block, Figure 9.

8. While holding the indexing tool in the position established in Step 6, install the leading arm of the linkage assembly over the splined section of the valve shaft. Use a 1/2" deep socket as a driver and tap it with a hammer to fully seat the linkage on the splines.

9. Re-install the valve shaft nut removed in Step 1. Tighten the nut to a torque of 8-10 lb.ft. (11-14 N-m).

10. Remove the indexing tool and save for future use.

NOTE: THE INDEXING TOOL IS FOR USE ON F-SUPER DUTY TRUCKS ONLY.
