ROCKER ARMS
Locate the rocker arms (Ref. No. 6 of Detail A in Diagram 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 point-
ing down. Align the holes in the channel with the rocker arm. Se-
cure 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 ac-
cesible 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
t he 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 com-
plete 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.
Tire Size and Carrying Capacity Chart
Tire Size ............................ST185/80R 13-C
GVWR ...............................5920 lb.
Carrying Capacity ............4600 lb.
Axle ...................................Disc Brakes
Refer to the tire side wall for correct tire pressure.
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.
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 cali-
per. 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 com-
ing 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 system 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.
DUAL AXLE BRAKE INSTALLATION
If your trailer is equipped with dual axle brakes connect the line to
the axle as follows: 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 to 6-8 ft. lb. or else 72-96 in. lb. of torque. DO
NOT OVER TIGHTEN. Over tightening will cause the brass block
to crack and then leak. Attach the brake hoses from the axles to the
spring bracket with the U-shaped hose clip. Once the brake hoses
are secured in place 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. Next connect the side
frame brake line into the top port on the tee. Connect the two axles
together using the 40” brake line supplied. Thread one end of the
line into the brass tee just installed. Route the line over to the other
axle, form a loop in the line and then connect the other end into the
brake line hose for the second axle.
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.
