Position the rear axle under the frame, then hook the hook loop of
the spring around the bushings just installed. If the axle is positioned
too low, the hooks will not hook around the bushings.
Raise the front of the springs up so they align with the rear
hole in the axle rocker arm. Secure in place with a 9/16” x
3-1/4” hex bolts and lock nuts.
Install another spring bracket bushing in the front hole on
the rock arm assembly. 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 in the rocker arm assembly. Swing the front of the
spring up and attach the front mounting hole in the spring brack-
et with another 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 the brake hose male end into
the port from which the plug was removed and tighten. Place
the other end of the hose up through the hole in the brake
line clip bracket (Ref #29). Secure with the hose clip.
Remove the plastic cap from the end of the frame brake line
coming out of the black plastic tube in the side frame by the
axle. Uncoil the brake line so that it will reach the end of the
hose just attached to the brake line clip bracket. Thread the
brake line fitting into the brake line hose. Tighten. All bleed-
ing to the line can be done through the bleeder on the right
caliper. For bleeding instructions see the ShoreLand’r Brake
Manual.
DUAL 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 the brake hose male end
into the block and tighten. Attach the brake hoses from the
axles to the spring bracket with the brake line clip brackets
as shown in Detail U. Once the brake hoses are secured
with the hose clips, the lines can be attached.
Identify which brake line hose that the side frame brake line
tubing will be connected to. In a dual axle installation it can
connected to either one. When identified, locate the brass
tee connector. Screw the male port of the tee into the brake
line hose. Tighten. (See Detail W.) Connect the side frame
brake line into the top port on the tee. Connect the two axles
together using the 40” brake line. Thread one end of the line
into the remaining port in the brass tee. Route the line over to
the other axle, form a loop in the line and connect the other
end into the brake line hose for the second axle.
Fill the actuator reservoir with brake fluid and bleed the line
per the instructions in the ShoreLand’r Brake Manual.
The axle is already bled at the factory during assembly.
Allremainder bleeding of the line can be done through the
bleeder on the right caliper.
White Ground Wire Installation
Place the self-tapping screw provided through the
round metal ring on the white ground wire of the tongue
harness located at the rear of the tongue. Attach the
ground wire to the main frame by driving the screw in the
hole provided next to the tongue channel of the frame.
This will assure a positive ground for the lighting.
Locate the brass brake line coupling. Remove the plastic cap
and thread the brake line coming out the rear of the tongue
into one end of the coupling. Bend the line in a smooth gradual
radius being careful not to kink the line. Bend the line so it
can be mated to the brake line from the side frame. Once
aligned thread the side frame brake line into the other end
of the coupling. Tighten both lines into the coupling.
SAFETY CHAINS
Locate the 1/2” x 5” hex bolt. Slip the bolt through a 1/2” flat washer
and through the last link of one of the safety chains.
Place the bolt with chain attached through the hole in the bot-
tom front of the actuator mounted on the tongue. Place the
second chain on the the bolt threads extending through the
other side of the tongue. Place on another 1/2” flat washer
and hex lock nut. Tighten.
ROCKER ARMS
Locate the rocker arms. Note: Center bushing has a grease
zerk in it. Position the rocker arms up into the center chan-
nel welded in the center of the tandem spring bracket so
that the grease zerk is pointing down. Align the holes in the
channel with the rocker arm. Secure with a 3/4” x 4-1/2” hex
bolt and lock nut. Tighten. Repeat this process on the other
rocker arm and spring bracket. Grease the rocker, apply
grease through the zerk.
NOTE: The grease zerk is positioned down so that it is
accessible for servicing.
SPRINGS
Position the axles so they are aligned with the trailer.
Position the brake axle so that the disc brake calipers are
on the back side of the axle. The brake axle must always
be mounted as the rear axle to give you the best braking
possible. There is no right and left to the axle
without brakes. It can be mounted either way.
Place the springs on the topside of the spring pads
welded to the axle. (See chassis diagram on Page 4).
Note: The hook end of the spring must be to the rear
of the trailer. Place a spring clamp on the top center of
the spring. The 1/2” x 6-1/2” U-bolts are placed down
over the top of the spring clamp, spring and axle.
Place the spring and axle U-bolt plate onto the ends of the
two U-bolts. Secure in place with 1/2” lock nuts. Do not tighten
securely until the adjustments can be made. Repeat on the
other spring.
AXLE
Place one of the spring bracket bushings (Ref. #35) 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.
