Wiring:

Plug in the tongue wire harness to the side
frame wire harnesses located on the first
crossmember. The white ground wire must
be grounded to the trailer frame with a 3/4”
self grounding tap screw.

White Ground Wire Installation

Pull the white wire out the hole in the tongue
with either the brown and yellow or brown
and green plug. Place the self-tapping screw
provided through the round metal ring on
the white ground wire of the tongue harness
just pulled out. Attach the ground wire to the

main frame by driving the screw into the
bottom flange of the side frame. This will
assure a positive ground for the lighting.

Brake line:
Place one end of the tongue brake line into
the hole in the top of the tongue located just
behind the front joint of the two side frames.
Insert until the end of the line comes out the
front of the tongue. Place the actuator into
it’s approximate location on the tongue.
Remove the plastic plug in the rear of the
actuator and thread the brake line into the
port. Tighten. Place the actuator in it’s
proper location by aligning the holes in the
mounting channel with the holes in the

Tongue:

Slip the tongue into the front frame cap of the frame. Line up the holes, fasten
the tongue in the frame with two (2) 1/2” X 3-9/16” X 5” square u-bolts, 1/2”
beveled aluminum washers, 1/2” stainless steel washers and 1/2” hex lock nut
with nylon inserts at the front of the tongue plates; fasten the tongue in the rear
at the front cross member location with a 1/2” X 4-1/2” hex bolt and 1/2” flat
washers under the nut and bolt. Refer to Detail E and F. Connect the tongue
brakline to the sideframe with a brakeline coupling (Ref.#30 on page 4).

Safety Chain:

Mount the safety chains to the front on the tongue using a 1/2” X 5-1/2” hex
bolt (Ref#4) with a 1/2” stainless steel flat washer at the head of the bolt,
followed by a safety chain through the drop tongue tube. Place the other safety
chain on the bolt on the opposite side of tongue and secure with a 1/2” stain­less steel flat washer and 1/2” stainless steel hex lock nut with nylon
insert. Refer to Diagram E.

tongue.

Actuator:

Mount the actuator (Ref#10) on the drop the
tongue using two (2) 1/2” X 4-1/2” hex bolts
(Ref#3) and 1/2” stainless steel hex lock
nuts with nylon inserts (Ref#7).

Place a grommet around the brakeline
where it comes out of the top of the tongue
to keep it from vibrating and chaffing as it is
being towed. Form the remaining end of the
brake line so it will mate up with the brake
line running down the side frame. Secure
the two lines together with the brass
coupling provided in Hardware box 66801.
Tighten securely to prevent leaks but do not
over tighten causing the threads in the fit­ting to strip.

Final Assembly Instructions

Remove and sort the small parts from
the frame.

Reference Standing at the rear of the
trailer will determine the right and left
sides of the trailer for assembly
instructions.

Rocker Bogie:
Refer to Detail H, Page 6. Note there
is a grease zerk in the center
bushing of the rocker bogie. Position
the rocker bogie into the center
mounting channel of the spring
bracket so that the grease zerk is
pointing down. This is necessary so
that it can be serviced in the field
when needed. Align the center hole of

the rocker (6239210) with the center
hole of the spring bracket. Insert and
secure with a 3/4” X 4-1/2” hex bolt from
the outside in and tighten with a 3/4” hex
lock nut.

Axles:
Note: The hook end of the springs must

point to the rear of the trailer, on both
axles!

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.
Place the springs on the topside of the
spring pads welded to the axle. (See
chassis diagram). Place a spring clamp
on the top center of the spring. Place
the 1/2” x 6-1/2” U-bolts 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.
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.
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,
hook the hook loop of the spring around
the bushings just installed. Note that if
the axle is positioned too low when
trying to hook, 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
bogie 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
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 just installed in the rocker arm
assembly. Then 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 Installation:

Open hardware box No. 66801 and sort.
Locate the long (88’) brake line and
straighten.

Locate the five (5) line clamps and the
1/4” self tapping screws. Form the brake
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 the other end of the brake line
into one of the ports on the brass block.
Thread the 18” brake hose male end 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. 27 in
Diagram F, Page 6.

Repeat this process on the second axle
using the component parts in hardware
box 66928.

Locate the brass tee in box 66928.
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 black plastic tube in
the side frame by the axle. 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 66928. 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.

Brakes:

Refer to the Brake Service Manual for
service and maintenance.

Trailer Adjustments:

The adjustment of the trailer to your boat is very important
not only for the trailer, but also the boat. Failure to do so may
lead to potential failure or damage to either the trailer or boat.

RB and ROLLER

The keel of the boat must rest on the center of the front keel
roller system creating a three-point support system. The keel
roller system is designed to fit most boats without needing
any further adjustment.

Rear Support System

Place the boat on the trailer so that the transom is located at
the rear of the support system. On an RB bunk trailer, the
transom of the boat should be within 1-2” of the end of the
bunk. The center of the rear rollers on the roller rack should
be approximately 4” from the transom. This gives you
maximum support on the transom.

The rear cross member is adjustable forward or backward to
allow the trailer to be adjusted to various length boats. This is
accomplished by removing the two bolts that attach the ends
of the rear cross member to each side frame. Slide the
assembly to another set of holes provided in the side frames
that is more desirable, and then re-attach the cross member
in the new location with the bolts just removed.

The wire harness for the three-light identification light must
be re-positioned where it comes from the black wire harness
tubing to eliminate slack and sagging of the wiring.

BUNKS

The bunks must be positioned far enough apart to give your
boat as much stability as possible while transporting.
Position the bunks so they are located just to the outside of a
strake that your boat may have. This will help center your
boat and assist when loading. The bunks need to be adjusted
up high enough to keep the keel from resting on the center
pads. A minimum of one to two inches of clearance is
desirable.

RB BUNK trailers would be adjusted the same way.

Once the boat is resting on the roller cradle assembly, the
stabilizer pads can be adjusted. Slide the pad up against the
boat bottom by hand. It is not necessary that they carry much
weight. They are designed to give your boat added stability
while being towed. It may be necessary to adjust the
assembly up so that they can be moved further apart giving
additional support. Pull the assembly away from the boat.
Place the U-bolt that holds the assembly to the cross
member in a lower hole in the bracket. Then push the
assembly back against the boat. Tighten in position.

Winch Post:

Slide the winch post base backward on the tongue until the
bow roller comes in contact with the boat. This bow roller
needs to be positioned directly above the boat bow eye to
prevent your boat from moving forward in the event of a
sudden stop. It can be moved up or down by sliding the winch
post angle tube either forward or backward on the tongue,
thus raising or lowering the bow eye roller. Attach the winch
strap and crank winch tight.

It may also be used to keep your boat on the trailer while
loading and unloading at the ramp, especially with a roller
trailer.

Tighten all bolts and U-bolts at this time in the winch post
assembly not previously tightened.

Attach the bow eye safety chain into the bow eye of the boat
as well. This is just another added level of protection to keep
your boat and trailer together as one unit.

ROLLERS

Position the roller racks so they are far enough apart to give
your boat stability while transporting. When the desired width
is achieved, move the roller rack system so that the rollers
are just to the outside of a strake. The rollers need to be
adjusted so that you have a minimum of one to two inches of
clearance between the keel of the boat and the center cross
member pads. This will help center the boat when loading
and unloading.

When the desired position is determined, tighten only enough
to hold the bunks or rollers from moving while the other
adjustments are being made. Final tightening will be done at
the end of the adjusting process.

Front Support System

BUNK

The front bunks should be adjusted either in or out so that
the bunk will run just to the outside of the strake of the boat.
The bunks can be adjusted either farther in or out from the
location of the rear bunk position. Adjust the bunks up so that
there is approximately 1” clearance between the keel of the
boat and the center cross member pad.

Midwest Industries, Inc. Ida Grove, IA 51445 [phone] www.shorelandr.com M303145

Axle Adjustment:

The amount of tongue weight on you trailer can be adjusted
as follows:To lower the tongue weight, adjust the axle
assembly forward. To increase the tongue weight, adjust the
axle assembly 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 on 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: Brake line and wire harness will need care when
moving the assembly.

NOTE: Check all fasteners, they must be tightened
before towing.

Cautions / Warnings

The law requires that the white ground wire on both the
tongue wire harness and the vehicle harness be
properly grounded to the respective trailer and vehicle
frames.
