INSTALLATION STEPS CONTINUED
5. Attach the sideplate flanges to the cross arms using (2) 1/2" x 1 1/2" hex bolts with 1/2" washers and 1/2" lock
washers. Thread them through the inside of the sideplate flanges into the crossarms. (Finger tight only!)
6. Fishwire the 5/8" bolts and spacers into position through the access holes and attach the sideplates to the frame using
(2) 5/8" flange nuts on each side. (Finger tight only). See Figure 2.
7. Using the 1/2" hardware supplied install the (CM-60604-T) template between the cross arms with the arrow pointing to
the front of the vehicle as shown in figure 3. Using the template, drill through the center hole with a 1/4" drill bit into the
bed of the vehicle.
8. After drilling the pilot hole, remove the template. Using a 4" hole saw or saber saw (with metal cutting blade),
enlarge the hole for the center section to pass through.
9. Install the center section by carefully raising it above the fuel tank from beneath the truck. Insert (4) 1/2" x 1 1/2" hex
bolts with a washer and lock washer through each of the slots on the inside of the center section, and thread them finger
tight into the rear crossarm. Repeat that process for the front crossarm. While installing the center section, be sure
the round hitch cylinder that protrudes from the top of the center section is positioned towards the rear of the
truck and is centered in the hole in the bed of the truck.
10. Disconnect lifting device if used and square center section to frame rails.
11. Torque all 1/2" fasteners to 110 ft-lbs, and all 5/8" fasteners to 210 ft-lbs in the
following order:
First: Torque the center section to the front and rear crossarms.
Second: Torque the sideplates to the truck frame on both sides.
Third: Torque the sideplate flanges to the front and rear crossarms.

WARNING!
INCORRECT INSTALLATION OF 60607 SAFETY CHAIN U-BOLTS MAY RESULT IN VEHICLE DAMAGE
60607 safety chain u-bolts, be sure to use the u-bolt slots nearest the 60607 cylinder. This will prevent contact of the
safety chain u-bolts with the vehicle fuel tank. Installation of u-bolts in outside slots may result in puncturing of the
