STEP 2: Using a center punch, tap into the frame at the center of the marked holes
using a hammer.
NOTE: BEFORE DRILLING, BE SURE TO CHECK THE BACKSIDE OF THE FRAME
FOR POSSIBLE HAZARDS.
At the punch mark, drill a 19/64” hole in the frame.
STEP 3: Using (8) self tapping bolts tap the holes using a 3/8” drive ratchet and 13mm
socket, and start each bolt by hand. When tapping the holes it is found best to start the
thread cutting, and every 1/2 - 1 full turn, back the bolt out to clear any metal chips, then
proceed with another 1/2 - 1 full turn and repeat until the holes have been properly
tapped.
NOTE:
DO NOT USE AN AIR OPERATED IMPACT GUN OR RATCHET AS THIS
MAY DAMAGE OR STRIP THE SELF TAPPING BOLT.
After all holes have been tapped you can attach the nerf bar. Start all the bolts, align the
side step as needed and tighten all bolts. Torque all bolts to 35 – 45 foot-pounds. Be
careful not to over tighten. Over tightening may stress these bolts and cause premature
failure. Recheck the torque of the bolts after a few days, and re-torque as needed.
