Tongue Assembly

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” belveled aluminum washers, 1/2” stainless steel washers and
1/2” hex lock nuts with nylon inserts at the front of the tongue plates; fasten
the tongue in the rear with a 1/2” X 4-1/2” hex bolt and 1/2” flat washer
under the nut and bolt.

Safety Chain:

Mount the safety chains to the front of the tongue using 1/2” X 1-1/2” 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. Secure with 1/2”
stainless steel hex lock nuts with nylon inserts on the inside of the drop
tongue tube.

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 58” tongue brake line
(Located in box No. 68140) 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 its approximate
location on the tongue. Remove the plastic
plug in the rear of the actuator and thread
the brake line into the port. Tighten. Align the
actuator to be mounted to the tongue. 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.

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

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 68140. Tighten to
prevent leaks but do not over tighten.

a location that best fits your watercraft. Secure
the winch post base weldment (Ref#2) to the
tongue using two (2) 1/2” X 3-9/16” X 5” square
u-bolts (Ref#11) and four (4) 1/2” stainless steel
hex lock nuts with nylon inserts. Mount the winch
post angle tube weldment (Ref#3) on the tongue
tube at a height that would best fit your watercraft
using a 1/2” X 3-9/16” X 5” square u-bolt over
the flange as shown in the drawing. Place the

Brake Line Installation

Remove balance of items from hardware box No. 68140 and
sort all items. Locate the long (90’) brake line and straighten
out by uncoiling.

Locate five (5) of the 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 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. 33 on page 6.

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 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 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 Shore-
Landr’s Owners Manual. Re-torque the lug nuts after 50
miles of driving and then periodically thereafter.

Repeat this process on the second axle.

Rear Bunk Assembly

Rear Bunk Assembly:

Mount the rear bunk support weldments to the pivot weldments by plac­ing them in the channel of the pivot weldments and attaching with 1/2” x
4-1/2” hex bolts and lock nuts. Place the bunk assembly over the sup­port weldment, align the holes of the bunk brackets with the holes in the
support weldment and secure using 1/2” x 1 1/2” carriage bolts and lock
nuts. Tighten but do not over tighten because the bunks must rotate to
conform to the boat bottom.

Note: The bunk pivot base weldment is adjustable on the front cross.
Loosen the 1/2” U-bolts (Ref#3, Page 14) enough to move the bunk
pivot base weldment in or out on the front cross to a location that best
conforms to your watercraft.

TRAILER ADJUSTMENTS

When the desired position is determined, tighten only enough
to hold the bunks or rollers from moving while the other

Axle:

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.

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
Best towing is achieved when the tongue weight is 5-7%
of the total gross load of the complete unit.

that there is approximately 1” clearance between the keel

of the boat and the center cross member pad.

NOTE: Brake line and wire harness will need care when
moving the assembly.

RB and Roller

The kee l 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
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

boats without needing any further adjustment.

Once the boat is resting on the roller cradle assembly, the

stabilizer pads can be adjusted. This is accomplished by

sliding 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

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
Make sure the bunks are 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.

Winch Post:

Now that all other adjustments are complete the winch post

can be adjusted. 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 back-

ward on the tongue, thus raising or lowering the bow eye

roller. Attach the winch strap and crank winch tight.

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
