10-08-45-001D Information for Electrical Ground Repair - Use New Replacement Fasteners with Conductive Finish - (Feb 14 2013) - part 4
Remove paint and primer from the area surrounding the 10 mm (0.40 in) until bare metalis visible.
Important:The M6 conductive rivet stud as shown, can accommodate a panel thickness range of0.7-4.2 mm (0.03-0.17 in). If there are layers of sheet metal, they should be touchingwithout any air gaps to ensure a good ground.Select a M6 conductive rivet stud. Refer to the Parts Information section of thisbulletin.
Note:Use the GE-50317 rivet stud tool kit.Place the M6 conductive rivet stud (1) in the 10 mm (0.40 in) hole. Assemble the rivetstud tool (2) with the groove and flare side facing the rivet stud, then the washerand the M6 nut (3).
Using a wrench on the rivet stud tool, and a socket on the M6 nut, secure the M6 conductiverivet stud.Ensure the new rivet stud is securely fastened, WITHOUT ANY detectable movement.Completely wrap the threads of the rivet stud with painters tape or equivalent.
Note:The rivet stud and surrounding panel area MUST BE properly refinished PRIOR tothe installation of the electrical ground wire terminal and conductive nut to maintaina secure, stable and corrosion-free electrical ground.Refinish the repair area using an anti-corrosion primer. Refer to Anti-Corrosion Treatmentand Repair in SI.Allow the refinished repair area to cure sufficiently before removing the protectivematerial applied to the rivet stud threads.Remove the painters tape or equivalent from the rivet stud threads.Using GM approved residue-free solvent or equivalent, thoroughly clean the rivet studthreads to remove any adhesive and allow to dry.Using a small brush, apply Dielectric Lubricant GM P/N 12377900 (Canadian P/N 10953529)to the threads of the M6 conductive rivet stud.
Note:Fretting corrosion is a build-up of insulating, oxidized wear debris that can formwhen there is a small motion between electrical contacts. The oxidized wear debriscan accumulate at the electrical contact points causing the electrical resistanceacross the connection to increase.Carefully remove ANY corrosion or contamination that may be present on the electrical ground wire terminal.Install the electrical ground wire terminal to the M6 conductive rivet stud.Select a M6 conductive nut. Refer to the Parts Information section of this bulletin.Install the M6 conductive nut to the rivet stud and:
Tighten to 8 Y (71 lb in)Verify proper system operation.Parts Information
