FINAL ASSEMBLY INSTRUCTIONS

Remove the hardware bag from the frame, remove
parts and sort by size.

R SERIES

The R-series roller rack is installed by placing the roller arm
assembly mounting channel over the rear cross member and
securing in place with a 1/2” x 4-1/2” hex bolt and lock nut. (See
Diagram A). Note that it should be left loose until the boat is
placed on the trailer. Once the proper positions is determined, it
may be tightened. Repeat on the other roller arm
assembly.

The short stabilizer bunk is installed to the adjustable bunk
bracket on the front cross member with a 3/8” x 1” hex bolt
and lock nut. (See Diagram A, Detail C).

TONGUE

The tongue is shipped separate of the frame. Locate the
appropriate tongue and install by sliding it in the front of the
tongue channel.

Line the holes in the tongue with the holes in the tongue channel.
Install the 1/2” x 4” hex bolt in the front cross hole and secure with
a 1/2” lock nut.

Remove the wire harness from the rear of the tongue. Place the
wire harness and the brake line through the hole provided in the
tongue cover plate. See Detail A in Diagram A.

Secure the tongue cover plate in position with the same 1/2” x 1­1/2” hex bolt that secures the back on the tongue to the tongue
channel of the frame. Secure with 1/2” lock nut. Tighten both bolts
just installed.

Plug the tongue wire harness ends into the frame harnesses by
matching colors and ends. Push the extra wire provided either into
the rear of the tongue or remove the grommet in the side frame
and place the extra wire in the side frame. Replace grommet just
removed.

WHITE GROUND WIRE INSTALLATION

Place the self-tapping screw provided through the round metalring
on the white ground wire of the tongue harness located at the rear
of the tongue. Attach the ground wire to the main frame by driving
the screw in the hole provided next to the tongue channel of the
frame. This will assure a positive ground for the lighting.

SAFETY CHAINS

Locate the 1/2” x 1-1/4” hex bolt. Slip the bolt through a 1/2” flat
washer, then place through the last link of one of the safety chains.
Place a second flat washer on the bolt and insert through the hole
as shown in Diagram B. Secure with a 1/2” flange lock nut. Tighten.
Repeat
this process on the second safety chain on the opposite side of the
tongue. Assembly is complete.

BRAKE LINE

Locate the brass brake line coupling. Remove the plastic cap and
thread the brake line coming out the rear of the tongue into one
end of the coupling. Bend the line in a smooth gradual radius being
careful not to kink the line. Bend so it can be mated to the brake
line from the side frame. Once aligned, thread the side frame brake
line into the other end of the coupling. Tighten both lines into the
coupling.

WINCH POST ASSEMBLY

The height that the bow eye is placed in your boat will determine
the length winch post required. Once this is determined, attach the
winch base to the tongue with three 1/2” x 4-1/2” carriage bolts and
lock nuts.

Align the holes in the Profile 2000 mounting channel with the holes
in the top of the winch base. Attach the front of the winch head
mounting channel to the base by placing a 1/2” x 4-1/2” hex bolt
through the hole closest to the front of the winch base. Secure with
a lock nut. Do not tighten.

Note that the winch head can now be rotated either up or down.
Identify the correct hole combination to use to position the bow eye
roller just above the bow eye of your boat. When determined, se­cure in this position by placing the bushing as shown in Diagram C
inside the winch base so it aligns with the hole just identified for the
proper adjustment. Insert another 1/2” x 4-1/2” hex bolt through the
determined mounting hole in the mounting channel and winch base
making sure the bolt passes through the bushing as well. Secure
with a 1/2” lock nut.

Tighten all bolts.

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 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 accesible
for servicing when needed.

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.

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

Midwest Industries, Inc. Ida Grove, IA 51445 800.859.3028 www.shorelandr.com 0003560

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 U­bolts 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.
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.

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 cali­per. Thread in the brake hose male end 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. 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 com­ing 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 ShoreLand’r 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.

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.

Adjust as follows:

AXLE ADJUSTMENT

The amount of tongue weight on your trailer can be adjusted as
follows:

To lower the tongue weight, adjust the axle assembly forward. To
increase the tongue weight, adjust the axle 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 of 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: Wire harnesses and brake line lines will need care when
moving the axle assembly.

REAR SUPPORT SYSTEM

Place the boat on the trailer so that the transom is located at the
rear of the support system. The center of the rear rollers on the
roller rack should be approximately 4” from 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 pivot bolt that holds each end of the rear
pivot to the side frame. Reposition the rear pivot arm into the other
hole position predrilled in the side frame.

Reattach the rear pivot to the side frame with the bolts just re­moved. Tighten.

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

FRONT ROLLER SUPPORT SYSTEM

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. It is a rare occasion when the front roller cradles will have
to be raised. However, due to variances in boat bottoms, the need
may arise that you may need to raise the roller cradle higher to sup­port the boat properly.

This is accomplished by adding an optional SS1003 riser bracket
that will raise the front roller cradle assembly ¾”. A second kit can
be added to raise the roller system a total of 1 ½”.

Once the height of the roller cradle assembly is established 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 just 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

Once 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 removing the back bolt
that mounts the winch head to the base. When this bolt is removed,
the head can be rotated up or down to reach the desired height re­quired to fit your boat. Once in this position, align the closest pair of
holes in the brackets and reinsert the bolt just removed. Tighten.

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

Adjustments are now complete. Double check your boat for fit. If the
desired fit has been achieved, tighten all fasteners that may have
either been left loose or have been loosened to do the adjusting.

The wire harness for the three-light identification light must be re­positioned where it comes from the side frame to the rear pivot to
eliminate slack, and sagging of the wiring.

Note: All nuts and bolts must be tightened before towing. The law
requires that the white ground wire on both the tongue wire harness

and vehicle harness be properly grounded to respective trailer

and vehicle frames.

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.

Recheck all fasteners on the complete trailer to make sure
they are all tight and ready for towing. All fasteners should
be periodically checked before towing.

See your ShoreLand’r Owner’s Guide for further technical
information regarding your trailer and its components.
