• Remove the fastener and ground wires and clean the area, front and back, using a tool such as a *3M(TM) Scotch-Brite Roloc disc or equivalent.
• Install the grounds, then the new washer and new bolt to the frame. You may have to enlarge the hole
• IMPORTANT: USE the NEW bolts, washers and nuts specified in this bulletin. These parts have been identified due to their conductive finish.
