Position the link arm drill guide (P/N S100-619-4003) against the control column elevator bearing assembly, aligning the la rge bolt hole in the drill guide with the existing bolt hole in the bearing assembly. Ali gn 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 pa d 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 th e 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.

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 asse mbly 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. 2. Reinstall the crew seat s in accordance with the KODIAK® 100 Airplane Maintenance Manual. 3.
