5.4 Installation Procedure
SAFETY
INSTRUCTIONS
Even though the Anthony liftgate is easy to
install, the installation should be done with at
least two people.
1. Remove the banding securing the liftgate to the pallet.
2. Remove the rear bumper and bumper brackets from
the truck. Remove the tailgate, cables, latches, and
pivots.
Tip: The tail light lens screws must be relocated so they
are accessible from the rear of the truck. Use the
following steps to relocate the screws. If these
steps are omitted, the tail light lens screws will not
be accessible once the liftgate is installed.
3. Remove the tail light lens screws from the lenses and
pull the tail light assembly away from the truck.
4. In most applications, there will be a lip at the inner
edge of the tail light opening. Note the location of this
lip and re-install the tail light lens. The holes that are
drilled in Step 6 must go through this lip.
5. If there is no lip to secure the lens, use the provided
lens mounting bracket A-135165 to form an alternate
lip. Bolt the bracket to the existing threaded hole in
the tail light compartment using the provided 5/16-18
x 3/4 bolt.

Anthony Lifgtates, Inc. 14 L-501 Models

6. Drill two holes through the lens and the lip using
a #32 (0.116”) drill, to accept the #8 self tapping
screws. Make sure these screws will be accessible
once the liftgate has been installed.
7. To prevent possible cracking, enlarge the holes in the
lens only using a #18 (0.170”) drill.
8. Using suitable “S” hooks and lifting chain, insert
“S” hooks into the 5/8” holes in the liftgate H-frame.
Raise the liftgate with a hoist or forklift.
9. Position the liftgate so the mounting lip of the liftgate
is resting on the truck bed and is as far forward as
possible.
10. Clamp the liftgate securely to the truck bed, using
pipe clamps or ratchet straps on each side of the
bed. Make sure the liftgate is square to the truck
bed. Tighten the clamps or straps so that the liftgate
posts are perpendicular to the truck bed.
Tip: If the truck bed is not parallel to the ground, the
liftgate must be mounted so the liftgate posts are
perpendicular to the ground in order for the platform
to lay flat on the ground when lowered.

11. Check that the liftgate is as far forward as possible
and centered. Drill 3/8” clearance holes in the truck
bed using the square holes in the liftgate mounting
lip as a guide.
Mark the hole, center punch, and drill.
12. Insert five 3/8” x 1” carriage bolts through the square
holes and bolt the mounting lip of the liftgate to the
truck bed using flat washers, lock washers, and bolts
underneath the truck bed.
13. Install the lower support bracket to each liftgate post
using three 1/2-13 x 1” bolts, lock washers, and flat
washers.

Anthony Lifgtates, Inc. 16 L-501 Models
www.anthonyliftgates.com 800-482-0003
14. Position the liftgate so the lower support bracket is
flush to the bed.
15. Using the holes in the lower support bracket as a
guide, drill 3/8” clearance holes through the bed.
16. Bolt the lower support bracket through the bed using
3/8”-16 x 1-3/4” bolts. Use the reinforcement plate
shown on page 11 under the washers and nuts on
the underside of the bed.
Tip: The reinforcement plate and/or the lower support
bracket may need to be cut to fit some installations.
This is acceptable as long as at least two bolts
remain on each flange. If it is necessary to cut the
parts, use a rust preventive paint or cold galvanizing
compound to protect the exposed metal from rust.
WARNING
Always use a cutting torch in a
well ventilated area and, if in an
enclosed area, vent the fumes to
the outside. Breathing the smoke and fumes can
cause serious injury.
Always follow all State and Federal health and
safety laws and/or local regulations when using
a cutting torch. Also, follow all manufacturer’s
safety guidelines. If other people are present during
the installation of the liftgate, make sure they remain
clear of the cutting area.
To avoid eye injury, always wear eye protection
with the proper lens to protect your eyes.
Tip: There are two sets of mounting straps furnished,
of different sizes. Use the size that best fits your
installation.
17. Install the mounting straps and strap washers to the
liftgate post using 1/2-13 x 1” bolts. Do not tighten
the bolts yet.
18. Slide the mounting strap to the edge of the bed. Drill
through the holes in the mounting strap, through the
lip of the bed, and secure the mounting strap with
3/8-16 x 1-3/4” bolts. Tighten the bolts in the liftgate
post.

L-501 Models 17 Anthony Lifgtates, Inc.
800-482-0003 www.anthonyliftgates.com
19. Bolt the four rubber bumpers to the corners of the
deck using 5/16-18 x 1” bolts.
20. Open the hood and disconnect the truck’s battery.
Uncoil the power cable and place it away from all
moving parts. Refer to the wiring diagram on page
20.
21. Install the 200 Amp fuse assembly within 30” of
the truck battery, and in a location that is easily
accessible for fuse replacement. Leave enough
slack in the cable to connect it to the positive (+)
post of the battery.
22. Secure the fuse assembly to a solid surface with
wire ties or other suitable fasteners, leaving a
minimum of 6” of slack in the cable for changing the
fuse.
23. Route the supplied power cable (with attached fuse
assembly) along the underside of the truck frame,
to the liftgate power supply using only one of these
three methods. Secure it at 18” intervals using the
supplied cable ties.
DANGER
Never secure the power cable to anything
which allows it to come into contact with sharp
edges, other wiring, fuel tank, fuel lines, brake
lines, air lines, exhaust system, or any other object
that could cause the power cable to wear or become
damaged. A direct short in the battery cable can
result in loss of vehicle control, serious injury, or
even death.

Direct Battery Connection
This method is not recommended because it allows
the unauthorized use of the liftgate when the truck is
unattended. Refer to “6.5 Direct Battery Connection
Option” on page 25.
Cut-Off Solenoid Connection
To prevent unauthorized use, use “6.6 Cut-Off Solenoid
Connection Option” on page 26.
Cut-Off Switch Connection
To prevent unauthorized use, use “6.7 Cut-Off Switch
Connection Option” on page 26.
WARNING
Anthony Liftgates strongly recommends the
installation of a power cut-off solenoid (“6.6
Cut-Off Solenoid Connection Option” on page
26) or cab cut-off switch (“6.7 Cut-Off Switch
Connection Option” on page 26). Allowing power
to the liftgate when the truck is unattended can result
in serious injury or death.
24. Cut the power cable to length, strip the end, and
crimp on a connecting lug per “6.3 Cable Lug
Installation” on page 24. Connect the power cable
to the pump solenoid post marked “BAT”. Use the
remaining cable and supplied lugs to ground the
pump to the truck’s chassis.
25. Using the supplied ground cable, ground the truck
battery to the frame.
NOTICE
The liftgate must be properly grounded. A ground
wire, the same gauge or larger as the liftgate
power cable, must be connected from the negative
post of the battery or batteries to the truck’s frame. If the
truck is properly grounded, no further action is required. If
the truck is not properly grounded, add a ground wire.
If this recommendation is not followed, damage to the
truck may occur. Improper grounding can cause the
electrical current to travel through brake lines, steel
braided power steering hoses, or other chassis wiring
causing failure to these components! Failure of these
components could result in loss of vehicle control.
26. Install the provided license plate bracket on the
streetside H-frame using two 5/16-18 x 3/4” bolts.
Install the truck license plate on the bracket.
27. Replace the license plate lights with the provided
lights by splicing into the existing harness. Install the
license plate lights into the holes in the bottom of the
pump reservoir compartment. Be certain to get all
the prongs on the light socket through the hole.
NOTICE
To prevent a blown fuse, make sure the truck battery is
disconnected before cutting the wires to the license plate
lights.

28. Lower the liftgate to the ground and check
hydraulic fluid level by removing the pump
reservoir compartment cover. The level should be
approximately 1/2” below the top of the hydraulic
reservoir. If the fluid level is low, fill to the proper
level with Mobil DTE-13, Pennzoil AWX, or Dexron II
automatic transmission fluid.
Note: Checking the hydraulic fluid level while the liftgate
is raised will result in overfilling.
CAUTION
Do not mix hydraulic fluid with brake fluid, and do not
use brake fluid in place of hydraulic fluid.
29. Discard the shipping plug in the hydraulic fluid
reservoir and replace with the supplied breather cap.
Tip: Certain models may already have a leak-proof
breather cap in place. If so equipped, it is not
necessary to replace the shipping plug.
30. Install the provided safety decals in the locations
shown. Refer to”7. Decals” on page 27.
WARNING
To prevent personal injury from not being
aware of safety recommendations, make sure
all decals are attached to the liftgate and/or
truck and are legible at all times!
Safety decals provide a vital role in helping reduce injury
and/or death. To ensure the greatest level of safety, all
