5.2 Prepare Holes for New Wear Pads 

1. Position the link arm drill guide (P/N S100-619-4003) against the control column 

elevator bearing assembly, aligning the large bolt hole in the drill guide with the 

existing bolt hole in the bearing assembly. Align the lower edges of the drill guide with 

the outside edge of the bearing assembly ear. 

Figure 5-3: Correctly Positioned Drill Guide 

2. Temporarily secure the drill guide to the bearing assembly ear with the nut and bolt 

removed previously. Stack sufficient washers on the bolt to provide a tight fit of the 

drill guide against the bearing assembly ear. 

3. Match drill two (2) holes into the elevator bearing assembly ear with a #40 drill bit. 

4. Remove the drill guide. 

5. Deburr the newly drilled holes. 

5.3 Install the Wear Pads 

1. Position one (1) wear pad (P/N 100-619-0037) on each side of the bearing assembly ear 

aligning the two (2) holes in each wear pad with the holes just drilled through the 

bearing assembly ear. 

2. Temporarily secure the wear pads in place with one (1) #40 cleco. 

3. Upsize the open hole in the wear pads and bearing assembly ear with a #30 drill bit. 

4. Temporarily secure the wear pads in place with a second #30 cleco and remove the first 

cleco. 

5. Upsize the open hole in the wear pads and bearing assembly ear with a #30 drill bit. 

6. Remove the cleco and wear pads from the bearing assembly ear. 

7. Deburr the upsized holes in the bearing assembly ear and ensure the wear pads are free 

of any aluminum debris. 

8. Position the wear pads on both sides of the bearing assembly aligning the mounting 

holes just prepared and secure them in place with one (1) #30 cleco. 

9. Insert one (1) pulled rivet through the open mounting hole and place one (1) washer 

(P/N NAS1149FN532P) over the tail of the rivet.

10. Permanently secure the wear pads in place with the rivet and washer. 

11. Remove the cleco and repeat the rivet and washer installation through the second hole 

in the wear pads and bearing assembly ear. 

5.4 Reassemble the Control Column Elevator Link 

1. Raise the elevator link into position and thread the bolt removed previously through the 

hole in the end of the link and the bearing assembly ear. 

2. Secure the elevator link to the bearing assembly ear with the nut and washers removed 

previously, torque the nut to 5 in-lb and then back off one castellation. 

NNNOOOTTTEEE

Ensure the nylon (self-locking) feature of the nut is in good condition. Replace the nut if needed. 

3. Install a new cotter pin (P/N MS24665-134) through the nut and bolt. 

4. Check the control yoke for smooth freedom of movement through the full range of 

normal motion and verify minimum wear pad extension beyond the anti-rotation guide. 

See Figure 5-4. 

Figure 5-4: Final Installation 

5. Repeat Section 5 for the opposite control yoke. 

6. Completion 

1. Clean up all chips and all other foreign object debris.
