B&W Trailer Hitches Turnoverball Model 1067 (Chevrolet_GMC) - Manual (Page 2)

INSTALLATION INSTRUCTIONS
STEP ONE - REMOVE SPARE TIRE AND HEAT SHIELD
The heat shield under the bed floor must either be removed or a section cut out for the
hitch assembly to be installed.
A) Remove the heat shield from in front of the back crossmember.
B) Remove the heat shield from the back of the crossmember located near the front
of the wheel well.
STEP TWO - REMOVE EXHAUST BRACKET
To ease installation of the center section, remove the lower exhaust bracket. Simply pull
the hanger rod out of the rubber bracket hole and a 6” to 8” wood block can then be
positioned between the exhaust pipe and frame of the truck. This will increase your clearance between the top of the
exhaust pipe and the bottom of the truck bed floor. (Caution: Exhaust pipe may be hot).
STEP THREE- MARKING AND CUTTING 4 INCH HOLE IN TRUCK BED FLOOR
Begin by verifying and measuring the correct hole location in the truck bed floor. Measure from the back end (tail- gate
end) of the truck bed floor by hooking a tape measure over the back of the truck box and mark the floor at the correct
measurement. Next, center the location between the wheel wells. This will be the center point for the four inch hole. This
location is critical to the correct installation of this hitch, so measure, mark and saw carefully. If the truck has a plastic
bed liner, you may drill through both, but it is more difficult to accurately locate the midpoint between the fender wheel
wells, and to be sure that the bed liner does not move while sawing the hole. Make a 4 inch hole at this location using a
four inch hole saw, or by marking a 4 inch circle and cutting it out with a saber saw equipped with a metal cutting blade.
STEP FIVE - CROSS MEMBER INSTALLATION
Place the 48” front cross member (1) between the truck frame and bed floor using
the notch made in step four. Be sure the holes in the cross member are facing
to the rear of the truck. Slide the cross member across both frame rails. Using
the rubber O-ring provided, secure a 1/2” 1-1/2” long bolt into the second hole
in the cross member from the drivers side. Slide the
crossmember forward to the front edge of the 4” hole
in the bed. Next install the 46 1/2 ” rear cross member
bar (2) between the truck frame and bed floor. Rotate
the rear cross member a quarter turn so the threaded
holes are offset to the bottom of the bar and slide back
until there is enough room for the center section to be
placed between the two cross members.
STEP SEVEN - INSTALL SIDEPLATES
Beginning in 2007 some models could be equipped with a factory installed trailer
brake system. In this case, a relay will have to be relocated before the driver’s side
sideplate can be installed. If the relay is present, there will be two bolt heads just
above the large oval hole in the frame on the driver’s side. Loosen these bolts and
slide relay to detach it from the frame.
Beginning in 2009 the models with factory installed trailer braking systems have a
wiring clip attached to the bottom of the frame on both sides of the truck just ahead
of the axle. This bracket must be removed and relocated as shown.
Next install the sideplates. The driver’s sideplate is shown, with the bent flange to the front, and the large holes to
the rear. Attach the two pieces of the sideplate together with ½” carriage bolts. The carriage bolts should be inserted
into the square holes from the backside of the sideplates and fastened using a flat washer, lock washer and nut on
each bolt. This can be completed before installation on the frame rail. Do not tighten at this time. Attach the flange on
the sideplate to the front cross member using a ½ x 1 1/2 inch bolt, flat washer, lock washer and nut. Insert the bolt
through the flange so that the nut when tightened is on the front side of the cross member. Next attach the rear bar
to the sideplate ear threading a ½ inch by 1 ½ inch bolt with flat and lock washer into the bar.
STEP SIX - CENTER SECTION INSTALLATION
Raise the center section into position between the crossmembers and carefully move
it above the fuel tank from beneath the truck. The receiver socket must be positioned
to the rear with the latch pin release arm on the driver’s side. A lifting device, as
described on Page 2 will help. The round hitch receiver that protrudes from the top
of the center section must fit through the hole in the truck bed floor. Slide the front
cross member back against the center section so that the bolt installed previously in
the front cross member goes into the center section hole directly across from it. Line
up the rest of the holes and attach the two members with 1/2” x 1 1/2” long bolts,
lock washers, and nuts. Insert four 1/2” x 1 1/2” bolts, with flat and lock washer in-
stalled, through the rear leg of the center section into the threaded holes of the rear
crossmember and hand tighten.

bed.
STEP FOUR - BED FLANGE MODIFICATION
Install the two cross members. They will be installed by sliding them from inside
the wheel well, above the tire, through the gap between the bed and the truck’s
frame and across until they span the frame rails. The gap between the bed and
frame is large enough to allow this, but the gap is partially obstructed by a sheet
metal flange (about 1” in height) that is hanging down from the bottom of the
truck bed floor. (See diagram and photos). A small notch needs to be made
in this flange on the passenger side of the truck. Locate the center truck bed
cross member. Measure over 2 1/2” from the front of the cross member and
make a mark. This will be the center point of the notch that is needed. Mark
a 1” wide by 1/2” tall notch. Remove the metal of the marked area with sheet
metal sheers. This will allow the front angle iron crossmember to be installed.
Step 1:
Locate the fuel valve.
Step 2:
Disengage the locking pin.
Step 3:
Slide fuel valve from bracket.
APPLICATION UPDATE:
Beginning in 2004, a fuel valve mounted on the rear of the fuel tank on trucks equipped with gas engines, makes it more difficult
to install the Turnoverball™ center section. This fuel valve can be easily removed and replaced to ease installation. Please follow
the following instructions:
Step 4:
Install Turnoverball™ Center Section.
Step 5: Replace fuel valve to bracket on fuel tank.
WARNING
On Short bed trucks, BEFORE INSTALLING THIS HITCH, check for adequate turning clearance between the front of all
of your trailers and the truck cab.
WARNING
DO NOT invert the ball in the socket when carrying heavy loads on 2 wheel drive trucks. The ball may hit the top of
the differential. Remove the ball from the socket before loading. A plug for the socket is available from B & W.
NOTICE
In some Truck models, plastic wheel well liners are present which extend past the side plate installation location on the
frame. A portion of the liner may need to be cut away over the area where the side plate will be installed.
Remove wiring clip
by pulling/prying
out of frame.
Install side plate and insert
clip into slot provided.
