Service Procedure

Figure 1:

NOTICE: Figures 1 through 4 are for gasoline engines. Although the servo rod assembly has a different shape and the servo may be rotated on diesels, the service procedure remains the same.

1. Raise hood and install a fender cover on the left fender.

2. Examine the cruise control servo. If the bushing in the bail of the servo looks like it was formed in place (a permanent part of the bail assembly - see Figure 1), go directly to Step (12) and install a Campaign Identification Label.

Figure 2:

If the bushing is a "snap-in" bushing (with tabs) as shown in View "B" of Figure 2, continue to Step (3).

3. Disconnect any electrical and hose connections, if necessary, to the air cleaner and remove air cleaner assembly.

4. Before removing the spring retainer from its adjustment hole in the servo rod assembly, scribe a mark on the rod next to the hole to identify where the spring retainer is to be reinstalled (see Figure 2).

5. Remove the spring retainer. Do NOT remove the "Z" pin.

6. Align the "Z" pin with the rod as shown in View "A" of Figure 2, then slide the rod rearward out of the bail (it may also be necessary to slightly collapse the servo diaphragm and move the bail forward).

Pinch the bushing flange with a pair of pliers and remove the bushing from the bail. The bushing may not be in the bail hole as originally installed; it may be free to move on the servo rod assembly. Remove and discard the old bushing.

7. If the servo bail hole has a burr, file off the burr so that the bail surface is flat on both sides.

8. Obtain bushing kit (part number 25111444). Install the bushing onto the bail as shown in Figure 3 so that the two tabs snap fimly in place. If the bail is bent (or twisted) so that the new bushing will not easily snap into place on the bail (as shown in Figure 3), straighten the bail as necessary.

9. Install the clip over the bushing and bail as shown in Figures 3 and 4. Reinstall the servo rod assembly through the new bushing by positioning the "Z" pin as shown in View "A" of Figure 2. Reinstall the spring retainer in the original (marked) hole in the rod, pointing the spring retainer in the direction shown in Figure 4.

If the servo rod assembly is missing the "Z" pin, install a second spring retainer in the end hole normally occupied by the "Z" pin.

10. Ensure that the throttle mechanism will return fully to the idle position.

11. Reinstall the air cleaner assembly and reconnect hose and electrical connections as may be appropriate.

12. Install a Campaign Identification Label, remove fender cover from left fender, and close hood.
