Information:

Use tool (E) in order to cut off the part of rivet (1) that has been peened. Remove rivet (1) from fuel injection control linkage (4) .

Use the 180-7951 Bushing Assembly Kit in order to modify the linkage. Insert 9X-8907 Hexagon Button Screw (9) from the 180-7951 Bushing Assembly Kit into fuel injection control linkage (4). Refer to Illustration 13.
Apply 169-5464 Quick Cure Primer apply on the threads of 9X-8907 Hexagon Button Screw (9) and 8L-5832 Hex Nut (8). Allow the primer to dry. The Quick Cure Primer counteracts the effects of the Volatile Corrosion Inhibitor (VCI) paper that was used to package the parts.
Assemble 180-7952 Lever Bushing (7) on 9X-8907 Hexagon Button Screw (9). Refer to Illustration 13.
Apply the 154-9731 Thread Lock Compound on the threads of 9X-8907 Hexagon Button Screw (9) and 8L-5832 Hex Nut (8) .
Illustration 14 g00655322
Place 8L-5832 Hex Nut (8) on 9X-8907 Hexagon Button Screw (9). Tighten 8L-5832 Hex Nut (8) until hex nut (8) is snug. Tighten 8L-5832 Hex Nut (8) for an additional 180 degrees.
Do not let metal chips or pieces of the rivet fall into the engine.
Illustration 15 g00655325
Clean the fuel injection control linkage and clean the surfaces of the cylinder head that are adjacent to the fuel injection control linkage with shop solvent. Remove the towels and remove all debris very carefully.
Install the 180-7956 Clamp Assembly Kit . Refer to the "Installation Of The 180-7956 Clamp Assembly Kit " section of this publication.Installation Of The 180-7956 Clamp Assembly Kit
Note: The 180-7956 Clamp Assembly Kit is used for the former control linkages only.Note: If the 180-7956 Clamp Assembly Kit is installed, refer to ""Modification of the 128-9640 Injector Synchronization Fixture "".The 180-7956 Clamp Assembly Kit may be installed on the fuel injection control linkage. The 180-7956 Clamp Assembly Kit will increase the strength of the joint.

Install 183-9390 Spacer (10) on fuel injection control linkage (4). Refer to Illustration 16.
Apply 169-5464 Quick Cure Primer to the threaded hole in the 180-7954 Clamp (11). Apply 169-5464 Quick Cure Primer to the threads of screw (13). Allow the primer to dry. The Quick Cure Primer counteracts the effects of the Volatile Corrosion Inhibitor (VCI) paper that was used to package the parts.
Apply 154-9731 Thread Lock Compound to the threaded hole in the 180-7954 Clamp (11). Apply 154-9731 Thread Lock Compound to the threads of screw (13) of clamp assembly. Loosely assemble 180-7954 Clamp (11) and 180-7987 Clamp (12) on fuel injection control linkage (4). Refer to Illustration 16. Be sure that the rivet head or bushing (14) is fully engaged into the counterbore of the
