Rocker Bogie
Locate the rocker bogie as shown on page 4. Note there is a
grease zerk in the center bushing of the rocker bogie. This is
necessary so that it can be serviced in the field when needed.
Position the rocker bogie into the center mounting channel of
the spring bracket. The rocker must be positioned with the
hole locations as shown for proper operation. Align the
center hole of the rocker 60205 with the hole in the center
mounting channel of the spring bracket. Insert a 3/4” x 5-1/2”
hex bolt from the outside inward as shown and secure with a
hex lock nut. Tighten. Repeat on the other rocker bogie.
Springs
Position the axles so they are properly aligned with the trailer,
which is the disc brake calipers are on the backside of the
axle. Block the axles so they are approximately 12” above
the floor. Drop two 1/2” x 2-9/16” x 6-1/2” U-bolts down over
the axle as shown (See Page 10), then down through the
holes in the spring mounting plate that is welded to the axle.
Position a spring so that the eye end of the spring is to the
front of the trailer. Raise the spring up between the U-bolts,
slip on another spring plate and secure with four 1/2” hex
lock nuts. Run the nuts up the threads but do not tighten until
after the springs are mounted into the trailer frame. Repeat
on the other end of this axle, then on the second axle.
Axles
Place the eye of the springs mounted on the rear axle into
the rear of the rocker bogies. Align holes and secure in the
rocker bogies with a 9/16” x 3-3/4” hex bolt and hex lock nut.
Raise the rear of the spring and axle assembly up into the
rear spring bracket channel. Place a spring support channel
(Ref. # 6) under the spring. Align the holes and place 9/16” x
4-3/4” hex bolt through one side of the spring support
channel and one side of the spring bracket channel. Next
place a spring bracket bushing on the top side of the spring,
(See Detail F) align with the bolt just inserted, then insert the
bolt completely through the bushing and the other sides of
the spring bracket channel and the spring support channel.
When completely inserted, secure with a 9/16” hex lock nut.
Place the eye of the springs mounted to the front axle into
the front spring bracket channel for the front axle. Secure as
above using a 9/16” x 3-3/4” hex bolt and hex lock nut. Raise
the rear of the springs up into the front side of the rocker
bogies. Raise the springs up and secure by placing under
the springs 9/16” x 3-3/4” hex bolts and hex lock nuts. Tighten
the bolts just installed.
Tighten all axle U-bolts and spring bolts not tightened at this
time.
Brake Line Installation
Open and remove parts from hardware box No. 68140 and
sort all items. Locate the long (90’) brake line and straighten
out by uncoiling on the concrete floor while walking on the
line as you uncoil. The line should be made as straight as
possible to assist in mounting to the axle.
Locate five (5) brake line clamps and 1/4” self tapping screws
provided in the kit. Hold the line on the backside of the axle
and familiarize yourself on how it needs to be formed to
connect to the brass blocks on the brake calipers. Form the
line so that it can be routed down the back side of the axle
and then over to the brass block on the calipers.
Remove one of the brass plugs from the port in the brass
block on the left brake caliper that best aligns with the routing
of the line. Note also that the bolt holding the brass block to
the caliper can be loosened so that the brass block can be
rotated to better accommodate the angle that the brake line
approaches the block on the caliper. Thread the brake line
fitting into this port to hold the line in position making sure
that the line does not rub or touch the spring. Re-tighten the
bolt in the brass block if it has been loosened to rotate the
block.
Route the line down the back side of the axle and secure to
the axle with the five (5) clamps and self tapping screws.
Note that the axle is pre-drilled for the mounting screws.
Route the brake line over to the brass block on the right brake
caliper. Remove both plugs on the right caliper block. Thread
this end of the brake line into one of the ports on the brass
block. Thread the male end of the 13” brake hose into the
other port from which the plug was removed and tighten.
Position the brass block so that neither the hose nor the brake
line will contact or rub the spring. Tighten all fittings.
Place the other end of the hose up through the hole provided
in the brake line clip bracket. Secure in place with the hose
clip provided. Item No. 32 on page 6.
Repeat this process on the second axle using the identical
component parts in the hardware box.
Locate the brass tee in box 68140. Thread the male port of
the tee into the female end of the brake hose of the front
axle. Tighten. 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 enough so that it will reach the
port of the tee just threaded into the brake hose. Thread the
brake line fitting into the top port of the tee and tighten.
Locate the 40” long brake line tube in box 68140. Thread one
end of the line into the remaining port of the tee installed in
the previous step. Route the line back to the second axle.
Place a coil in the line to use up the excess line and then
connect the other end of the line into the hose coming from
the second axle. Tighten both 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.
Tire and Wheel Assemblies
Mount the tire and wheel assemblies using the 1/2” fine
threaded tapered lug nuts provided. Tighten to 80-90 ft/lb. of
torque using the rotation pattern as shown in the
ShoreLandr’s Owners Manual. Re-torque the lug nuts
after 50 miles of driving and then periodically thereafter.
