Trailer Adjustments
The adjustment of the trailer to your boat is very
important not only for the trailer, but also the boat.
Failure to do so may lead to potential failure or
damage to either the trailer or boat.
Adjust as follows:
Axle Adjustment
The amount of tongue weight on your trailer can be
adjusted as follows:
To lower the tongue weight, adjust the axle assembly
forward. To increase the tongue weight, adjust the
axle assembly backward.
The distance that the axle assembly has to be moved
will vary because it is directly related to the weight
and center of gravity of the boat place on it.
Best towing is achieved when the tongue weight is 5-
7% of the total gross load of the complete unit.
To move the axle assembly, loosen the U-bolts that
secure the assembly to the side frames. Move the
assembly to the desired location then re-tighten the U-
bolts.
Note: The brake line and wire harness will need care
when moving the assembly.
Rear Support System
Place the boat on the trailer so that the transom is
located at the rear of the support system. On an RB
bunk trailer, the transom of the boat should be within
1-2” of the end of the bunk. The center of the rear
rollers on the roller rack should be approximately 4”
from the transom. This gives you maximum support
on the transom. The rear pivot is adjustable forward
and backward to assist in adjusting the trailer to
various length boats. This is accomplished by
removing the pivot bolt that attaches the rear pivot to
the side frame and then sliding the assembly to the
desired position and re-attaching with the pivot bolt
just removed. The wire harness for the three-light
identification light will have to be rerouted as well.
RB Bunks
Make sure the bunks are positioned far enough apart
to give your boat as much stability as possible while
transporting. Position the bunks so they are located
just to the outside of a strake that your boat may
have. This will help center your boat and assist when
loading. The bunks need to be adjusted up high
enough to keep the keel from resting on the center
pads. A minimum of one to two inches of clearance is
desirable. Connecting the Two Axles Together and To the
Actuator
Locate the brass tee. Thread the male port of the tee
into the female end of the brake hose of the rear axle.
Tighten.
Remove the plastic cap from the end of the frame
brake line coming out of the side frame by the axle.
Carefully pull the brake hose enough so that it will
reach the port of the tee just threaded into the brake
hose. Thread the brake hose fitting into the top port of
the tee and tighten.
Locate the 60” brake hose. Thread one end of the
hose into the remaining port of the tee installed in the
previous step. Route the hose thru the front brake line
clip on the spring bracket and secure to the hose to
the right caliper on the front of the second axle. Place
a coil in the line to use up any excess line and then
connect the hose coming from the second axle to the
side frame using clips with rubber inserts to keep the
line from being damaged. Tighten all fittings. Note that
the coil in the line will absorb the vibration created
during towing.
Bleeding the Brake System
Bleed the brake system as specified in the brake
manual. The bleeding process is necessary to remove
ALL air entrapped in the system in order for the brake
system to function properly.
