B&W Trailer Hitches 1100R - Manual (Page 3)

From the driver’s side wheel well, locate and release the brake line and fuel line retaining clip from
the frame rail. (The retaining clip is plastic, and snaps through a small hole in the frame from the
inside. It is located near the large hole in the frame.)
STEP FIVE
Square the assembled center section and crossmembers across the frame. Identify the left and right
side plates: The spacers with the 1” holes fit against the outside of the frame rails, with the narrow
end of the side plate facing the rear of the truck. Fasten the sideplates to the crossmembers using
1/2” X 1 1/2” bolts, flat washers on each side, and lock washer and but. Do not fully tighten at this
time. If you loosened the bed bolts in Step three , re-tighten them now.
Trucks without overload springs (Model # 1100R & 1150R)
Align the lower holes in each of the side plates with existing holes in the truck frame rails.
Fasten both sideplates using 1” bolts in the large holes with the 1/2” thick spacers installed between
the plate and frame. Fit the bolt with a flat washer through the hole from inside the frame and se-
cure with a lock washer and nut. Carefully check fuel and brake lines inside the frame rail and be
certain the fasteners will not damage them. Fit a 1/2” X 1 1/2” bolt with a flat washer from inside
the frame through the frame hole nearest the back of the sideplate. Secure with a flat washer, lock
washer and nut. Do not fully tighten at this time. When the crossmembers, center section and side-
plates are installed, torque all fasteners to 90-ft. lbs. in the following sequence. (Use caution not to
damage the brake line or fuel line.) First, torque the crossmembers to the center section. Second,
torque the crossmembers to the sideplates. Third, torque the sideplates to the frame rails.
STEP SIX
Trucks with overload springs (Model #1110R)
Align the 1” hole in each of the sideplates with the existing 1” hole in the frame rails. Fasten using
a 1” bolt. Fit a 1” bolt with a flat washer through the hole from inside the frame and secure with a
lock washer and nut. Carefully check fuel and brake lines inside the frame and be certain the bolt
or washer will not damage them. It is necessary to drill a 1/2” hole in the frame rails through the
slot nearest the front of the sideplate. (Jacking up the back of the truck will raise the frame higher
than the tire, making it easier to drill this hole.) Fasten with 1/2” X 1 1/2” bolts. Fit the bolt with a
flat washer from inside the frame and secure with a flat washer, lock washer and nut. Do not fully
tighten at this time.
NOTE: The sideplates for Model #1100R and Model #1150R can be modified to fit trucks with over-
load springs. To modify these sideplates to fit trucks with overload springs, cut 10” inches off the
back of the sideplates. The back is the narrow end of the sideplates. Install modified sideplates by
following the instructions in the paragraph above (model #1110R).
When the crossmembers, center section and sideplates are installed, torque all fasteners to 90-
ft. lbs. in the following sequence. (Use caution not to damage the brake line or fuel line.) First,
torque the crossmembers to the center section. Second, torque the crossmembers to the side-
plates. Third, torque the sideplates to the frame rails.
STEP SEVEN
To install the safety chain brackets it is necessary to drill four 1/2”
holes through the truck bed floor. Drill the holes from beneath the
truck, through the four holes farthest from the round hitch receiver
tube in the center section. Drop a U-bolt through each pair of holes
from the topside of the truck bed floor. Place a spring and lock nut on
each of the four legs. Tighten the lock nuts until 1/4” of thread ex-
tends through the lock nut.
