INSTALLATION
1.
The AERO 7500 Actuator is completely assembled and ready to bolt or weld into place onto straight three inch
wide trailer tongues. Welding will make repair or replacement difficult but may be preferred. If the actuator must
be painted for aesthetic reasons, then TITAN recommends painting ONLY the outer case and disassembling the
unit prior to painting. Application of heavy coats of paint may interfere with component operation. If the actuator is
welded on, then be sure to weld in a well ventilated area. Confirm the coupler and breakaway mechanisms work
properly before operation. Store actuators indoors and in their original shipping carton until the time of
installation.
3.
Since the AERO-7500 mounts flush to the top of the trailer tongue, the brake lines are best routed inside the
trailer tongue and frame. One way to simplify attachment of the actuator is to turn several coils in the tubing at the
actuator end. These coils can then be located inside the end of the tongue and will stretch the few inches
necessary to allow the unit to be connected, and will spring back as the unit is bolted in place. A short length of
flexible brake tubing is another option. DO NOT crush or kink the tubing as you mount the actuator.
4.
Install the hydraulic brakes and brake lines on the trailer as described in the installation manual supplied with the
brakes. TITAN recommends 3/16 inch brazed double wall tubing per S.A.E. J527 for use with all our actuator and
brake products. Use forty-five degree (45°) double-flare tube ends per S.A.E. J533. DO NOT remove or modify
the orifice connector <9> at the rear of your actuator's master cylinder. It connects directly to the brake tubing and
ensures proper fluid flow characteristics.
5.
After installation of the actuator, brake, and brake lines as described above, proceed immediately to the "BRAKE
FLUID FILLING AND BLEEDING" instructions.
2.
Bolt the actuator to the tongue using
1/2 inch by 4 inch grade 5 bolts,
nuts, and lock washers. The top two
holes
match
standard
coupler
mounting holes on three inch wide
trailer tongues, as shown in Figure 1.
The third hole is recommended for all
applications, but MUST be used for
trailers with a Gross Load greater
than 3500 pounds. Light weight
tongues require spacer tubes inside
for reinforcement such as a 3/4 inch
outside diameter by eleven gauge
piece of tubing. Using a torque
wrench, tighten bolts to eighty (80)
foot-pounds torque.
