Installation Instructions for Steel Frame
Trailers with a GVWR (Gross Vehicle Weight
Rating) Greater than 6,000 lb.
Use Kit No. TA0015
Actuator Coupler Installation
Removing the existing actuator from the tongue.
1. Unthread the tongue brake line fitting from the coupling that
attaches it to the frame brake line tubing.
2. Remove the mounting bolts that attach the actuator to the tongue.
Remove the actuator and tongue brake line. They will no longer be
used in the new installation.
3. Remove the safety chains from the tongue. The new safety
chains supplied in the kit will be installed.
4. Unplug the tongue wire harness from the frame harness using
the plug-in connectors. It will not be used in the new installation.
IMPORTANT
Note: The bolts in the kit used to attach the coupler and safety
chains on all trailers are stainless steel. Also the U-bolts for
attaching the mounting brackets for the actuator and the bat-
tery boxes on the aluminum trailers are stainless steel. They
require that you use the appropriate size nuts with the nylon
inserts. It is also recommended that you use an anti-seize
lubricant (supplied in the kit) on the threads before the nuts
are installed to prevent seizing when they are tightened. All
other U-bolts in the kit are plated steel and are used on the
steel frame trailers. The standard flange lock nuts are used
on these U-bolts.) Failure to mate the proper nuts with prop-
er U-bolts will cause the nuts to freeze when tightening thus
preventing the U-bolts from tightening properly.
Installing the New Coupler Assembly
1. Locate the electric over hydraulic ball coupler mounting bracket,
Item 2. (See Diagram D) Place it on the end of the tongue and
attach it with three (3) 1/2” x 4-1/2” hex bolts (Item No. 3)and lock
nuts. Tighten. Note that the bolt pattern in the coupler mounting
bracket is the same bolt pattern as the UFP 8,000 & 10,000 series
actuator. If your trailer is an earlier model the bolt pattern of your
tongue may not match the pattern of the coupler mounting brack-
et supplied. Your tongue will have to be re-drilled so the coupler
mounting bracket can be mounted to your tongue.
2. Attach the 2-5/16” coupler to the mounting bracket just installed
using 4- 5/8” x 1-3/4” hex bolts (Item No. 4) and lock nuts. Tighten.
Attach the new safety chains provided by placing a 1/2” flat wash-
er on a 1/2” x 1-1/2” hex bolt. Insert the bolt through the end link
on one of the new safety chains provided. Insert the bolt into the
mounting hole that the old chains were removed from. Secure with
the 1/2” flange lock nut. Tighten. Repeat on the other chain.
The breakaway switch shown in the diagram will be installed at a
later time. Instructions for mounting the breakaway switch follow
later in the assembly.
Electric Over Hydraulic Actuator Installation
1. See Diagram F on page 5. Locate the actuator mounting plate,
Item No. 2 and the brake actuator, Item No. 10. Place one each
5/16” lock washer on the three 5/16” x 1” hex bolts. Attach the brake
actuator to the mounting plate using the three 5/16” x 1” hex bolts.
Tighten.
2. Place the assembly on the inside of the side frame. Note that the
mounting plate has the appropriate holes for attaching to 2 x 4”,
and 2 x 5” steel side frame tubing as well as the aluminum I-beams.
Use the U-bolts to mount the actuator assembly to the side frame.
See the note at the bottom of the Bill of Materials listed for Diagram
F. Secure the U-bolts to the assembly using the 3/8” flange lock
nuts provided. DO NOT USE THE 3/8” NUTS WITH THE NYLON
INSERTS IN THEM BECAUSE THEY WILL GAULD UP AND YOU
WILL NOT BE ABLE TO TIGHTEN PROPERLY.
3. Place the proper U-bolts over the side frame as shown in
Diagram BB, insert through the mounting plate and secure with 3/8”
flange lock nuts. Position the mounting bracket on the frame so that
the front of the bracket is 32 inches from the front of the side frame.
See Dimension C in Diagram BB. Tighten.
4 Once the actuator is located attach the grounding ring on the
actuator white wire lead to the inside of the frame with a No. 10
self-tapping screw so continuity can be achieved through the paint
coating.
Brake Line Tubing Connection
1. Note that the frame brake line tubing in the steel frame exits
through a fixed hole position in the side frame. It needs to be routed
backwards to the new actuator location.
2. Locate the coiled length of brake line tubing supplied in the kit.
Uncoil the line and attach one end to the frame brake line using the
coupler that was used to connect the tongue brake line tubing to
the side frame tubing. Tighten.
3. Carefully bend and route the tubing backward, down the inside
of the side frame towards the actuator just installed. Care should be
used in forming the line so that it does not kink.
4. Route the brake line over to the port on the actuator as identified
in Diagram B. Coil any excess line you may have into a 3” diam-
eter coil to use up the excess. Tighten the brake line fitting into the
actuator.
5. Locate the brake line tubing clips and No. 10 self-tapping screws
provided. Place the tubing clip over the brake line while pressing
the brake line tubing up against the center inside of the trailer side
frame. Place a self-tapping screw into the hole in the tubing clip and
drill the self-tapping screw into the side frame of the trailer. Repeat
on the other clips.
Battery Box Installation
Steel Frame Installation
1. (See Diagram F) Locate the battery box mounting plate, Item
No. 1 and the battery boxes, Item No. 9. Note that there are two
battery boxes and two batteries. They are both required to power
the brake system in the event of an unwanted disconnect from the
tow vehicle.
2. Open the battery boxes and remove both the white and violet
wire harnesses that are shipped in one box. Also remove the break-
