Installation instructions – B&W Trailer Hitches Turnoverball Model 1150 (Ford) User Manual
Page 2
Mark a 4” round hole on the topside of the truck bed floor. Center the hole between the wheel wells
and place the center of the hole 49” from the tailgate end of the bed. Drill a small hole inside the area
marked and cut out the circle using a saber saw with a metal cutting blade or use a 4” hole saw.
INSTALLATION INSTRUCTIONS
Remove the heat shield located above the rear axle under the truck bed. The heat shield is attached
with four sheet metal screws (7/32” hex head). Replace the front screw after removing the heat shield.
STEP TWO
Before installing the crossmembers and center section, loosen the tail pipe hanger bracket in front of
the rear axle. Place a ratchet strap around the highest part of the tail pipe and the rear axle. Pull the
tail pipe down by tightening the ratchet strap to achieve sufficient clearance for hitch parts. After in-
stalling parts, insert a 1/4” shim in the tail pipe bracket and tighten. Cut the safety chain U-bolts, on
the exhaust pipe side, off to an inside length of 3 1/4”, and cut 1 1/2” off of the safety chain spring.
POWER STROKE DIESEL ONLY
Select the back crossmember (1) with the deepest notches at the ends. With the horizontal side up and
the slotted side facing the front of the truck, position it across the top of the frame rails, between the
bed and frame, by pushing it through the opening from the wheel well on the driver’s side. When the
cross member is across the frame rails, move it to the rear, up on the higher section of the frame rails.
Position it approximately 3” behind the hole in the truck bed floor, centered across the frame rails. This
can be accomplished more easily by loosening the bed bolts in the frame rails behind the axle. After
sliding the crossmember back 3” behind the hole in the truck bed floor, use a crescent wrench or chan-
nel locks on the slotted side of the crossmember to rotate it down on its long axis, placing the side
without slots flush against the truck bed floor. Position the front crossmember (2) in the same manner,
with the horizontal side up and the slotted side facing the rear of the truck. Locate the front cross-
member approximately 3” in front of the hole in the truck bed floor. The two crossmembers should be
approximately parallel, about 9” apart, equally spaced in front of and behind the hole in the truck bed
floor.
STEP THREE
With the latch pin arm on the driver’s side, raise the center section (3) into position between the cross-
members from beneath the truck. The round tube hitch receiver that protrudes from the center section
must fit through the round hole in the truck bed floor. Fasten the center section to the crossmembers
using the six 1/2” X 1 1/2” bolts. Fit these bolts through the slots in the crossmembers using a flat
washer and lock washer on each.
STEP FOUR
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 (4)
and right (5) 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 secure 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 crossmem-
bers, center section and sideplates are installed, torque all fasteners to 90-ft. lbs. in the follow-
ing sequence. (Use caution not to damage the brake line or fuel line.) First, torque the cross-
members 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 us-
ing 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
overload 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 side-
plates 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 (6) 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 extends through the
lock nut.
