Installing the New Coupler Assembly
1. Locate the new 2” coupler in the hardware box, Item No. 7 in
Diagram C. Note that this coupler must be used because it has a
6,000 lb. capacity rating which is greater than the standard Class II
or Class III couplers.
2. Place it on the tongue and attach using a 1/2” x 4” hex bolt (Item
No. 2) through the holes in the back of the coupler. Secure with a
1/2” lock nut.
3. Attach the front of the coupler to the tongue using two- 1/2” x 1-
1/2” hex bolts (Item No. 3) 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 E. 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 3/8” x 4 7/16” x 3” U-bolts for a 2” x 4” frame or the 3/8” x
5 7/16” x 3” U-bolts for the 2” x 5” side frame to mount the actuator
assembly to the side frame. See the note at the bottom of the Bill of
Materials listed for Diagram E. 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 Di-
agram A, 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 A in Diagram A) 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 A. 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 E) 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-
away switch that is shipped in the other box. Installation instruc-
tions for these items will be addressed at a later time.
3. Attach the two battery boxes to the mounting plate using 1/4” x
1” carriage bolts and 1/4” lock nuts as shown in Diagram E. Once
all bolts are installed, tighten.
4. Place the assembly on the inside of the frame as shown in Dia-
gram A and secure to the frame using two of the appropriate size
U-bolts as described earlier in the actuator assembly instructions.
Secure with 3/8” flange lock nuts. Position the battery box assem-
bly so it is 21 inches from the front of the frame to the front of the
mounting bracket as shown in Diagram AA, Dimension B. Tighten.
5. Attach the white ground wire just removed to the negative termi-
nals (marked with black plastic cap) of the two batteries. Route the
wire from one battery box to the other using the notch located in
the back side of the battery box.. Route the end of the wire harness
with the round grounding lead out the notch of the second box. Po-
sition it on the inside of the trailer side frame and attach with a No.
10 self-tapping screw. This is necessary so that a positive ground
is created for the system to function properly.
Breakaway Switch Installation
The breakaway switch provided is required so that the brakes on
the trailer will be applied in the event of an unwanted disconnect
from the tow vehicle.
1. Locate the breakaway switch, Item No. 8 in Diagram C. It was
shipped in one of the battery boxes along with a battery. Place it on
the topside of the tongue located just behind the coupler as shown
in Diagram C. It must be positioned so that the front of the break-
away switch is three (3) inches behind the coupler installed earlier.
This is necessary so that the pin in the switch can be pulled out the
front of the breakaway switch to automatically activate the brakes
