Place the spring and axle U-bolt plate onto the ends of
the two U-bolts just placed. Secure in place with 1/2”
lock nuts. Thread onto the U-bolts but do not tighten
securely until the complete unit is in position on the
trailer. Repeat on the other spring.
AXLE
Place one of the spring bracket bushings into the rear
of the spring bracket and secure with a 9/16” x 3-
1/4” hex bolt and hex lock nut. Repeat in other spring
bracket. Position the rear axle under the frame, then
hook the loop of the springs around the bushings just
installed. Note that if the axle is positioned too low
when trying to hook, the loops will not hook around
the bushings.
Raise the front of the springs up so they align with the
rear hole in the axle boogie just installed. Secure in
place with 9/16” x 3-1/4” hex bolts and lock nuts.
Install another spring bracket bushing in the front hole
on the rock arm assemblies. Secure with a 9/16” x 3-
1/4” hex bolt and lock nut. Tighten.
Hook the hook end of the springs mounted to the front
axle over the bushing just installed in the rocker arm
assembly. Swing the front of the spring up and attach
the front mounting hole in the spring bracket with an-
other 9/16” x 3-1/4” hex bolt and lock nut.
Tighten all axle U-bolts and spring bolts.
ONE AXLE BRAKE INSTALLATION
Cut the tape securing the brake line hose to the axle.
Remove the brass plug from the port in the brass
block on the right brake caliper. Thread in the brake
hose male end and tighten to either 6-8 ft. lb. or 72-96
in. lb. of torque.
DO NOT OVER TIGHTEN Over tightening will cause
the brass block to crack and then leak.
Place the other end of the hose up through the hole
provided in the brake line clip bracket. Secure in place
with the U-shaped hose clip provided.
Remove the plastic cap from the end of the frame
brake line coming out of the side frame by the axle.
Carefully uncoil the brake line so that it will reach the
end of the hose just attached to the brake line bracket.
Thread the brake line fitting into the brake line hose.
Tighten.
NOTE: The axle has brake fluid installed in the calipers
and the axle line when it is assembled at the factory.
This is done to protect the inner parts of the brake sys-
tem during shipping and storage. The complete brake
system including the axle MUST be re-bled to ensure
that all air has been removed from the brake system.
For bleeding instructions see the UFP brake bleeding
manual or the ShoreLand’r Disc Brake Manual.
Fill the actuator reservoir with brake fluid and bleed
the line per the instructions in the Brake Manual.
TIRE & WHEEL ASSEMBLY
Mount the tire and wheel assemblies using the 1/2”
fine threaded tapered lug nuts provided. Tighten to 85-
95 ft./lb. torque using the rotation pattern as shown
in the ShoreLandr’s Owners Manual. Re-torque the
lug nuts after 50 miles driving and then periodically
thereafter.
TRAILER ADJUSTMENTS
The adjustment of the trailer to your boat is very im-
portant not only for the trailer, but also the boat. Fail-
ure 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 assem-
bly forward. To increase the tongue weight, adjust the
axle 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 placed on it.
Best towing is achieved when the tongue weight is 5-
7% of the total gross load of the complete unit.
Note: Wire harnesses and brake line lines will need
care when moving the axle assembly.
REAR SUPPORT SYSTEM
Place the boat on the trailer so that the transom is
located at the rear of the support system. On a bunk
trailer, the transom of the boat should be within 1-2” of
the end of the bunk. This gives you maximum support
on the transom.
The rear cross member is adjustable forward or back-
ward to allow the trailer to be adjusted to various length
boats. This is accomplished by removing the pivot bolt
on holds each end of the rear pivot to the side frame.
Reposition the rear pivot arm into the other hole posi-
tion predrilled in the side frame.
