ROCKER ARMS
Locate the rocker arms (Ref. No. 6 of Detail A in Dia-
gram D.) Note that the center bushing has a grease zerk
in it. Position the rocker arms up into the center channel
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 in place 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 at this time by applying grease
through the zerk just discussed.
NOTE: The grease zerk is positioned down so that it
is accessible for servicing when needed.
SPRINGS
Position the axles so they are properly 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 (See Diagram D.) 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). Note that 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 as
shown. Next place the 1/2” x 6-1/2” U-bolts down over
the top of the spring clamp, spring and axle as shown.
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 another 9/16” x 3-1/4” hex bolt and lock nut.
Tighten all axle U-bolts and spring bolts.
BRAKE LINE
Locate the brass brake line coupling. Remove the
plastic cap and thread the brake hose coming out the
rear of the tongue into one end of the coupling. Once
aligned, thread the side frame brake hose into the
other end of the coupling. Tighten both lines into the
coupling.
ONE AXLE BRAKE INSTALLATION
Cut the tape securing the brake line hose to the axle.
Remove the plastic plug from the bottom port in the
brass blocks of both brake calipers. 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.
Remove the plastic cap from the end of the frame
brake hose coming out of the side frame by the axle.
Carefully pull the brake hose so that it can be
threaded thru the brake line bracket. The brake hose
will then be routed down to the side port in the brass
block on the right caliper. Thread the brake hose
fitting into the brass block. Tighten.
NOTE: The complete brake system including the
axle MUST be 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.
