FINAL ASSEMBLY INSTRUCTIONS
Remove the hardware bag from the frame, remove parts and sort
by size.
RB SERIES
The RB bunk system comes pre-assembled from the factory. Break
the bundle and center one of the RB bunk systems on the rear
pivot cross member of the frame. Locate two ½” x 3 9/16” x 3 7/8”
U-bolts. Slide a U-bolt up around the rear pivot cross member, align
the legs of the U-bolt with the holes in the mounting plate of the RB
bunk support tube. Insert the U-bolt through the holes and secure
with ½” flange lock nuts. Repeat on the second U-bolt. Tighten the
lock nuts only enough to hold in position. They will have to be readjusted when the boat is placed on the trailer.
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 B.)
Repeat the above process on the bunk on the other side of the
trailer.

Diagram B
Locate the brake line that is shipped in the brake line box. Uncoil
the line, then route down the inside of the tongue until it comes out
the rear of the tongue.
Align the holes in the tongue with the holes in the tongue channel.
Install the ½” x 4” hex bolt in the front cross hole and secure with a
½” flange lock nut.
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 ½” x 1 ½” hex bolt
that secures the back of the tongue to the tongue channel of the
frame. Secure with ½” flange lock nut.
Plug the tongue wire harness ends into the frame harnesses by
matching colors and ends. Push the excess wire provided back into
the rear of the tongue.
WHITE GROUND WIRE INSTALLATION
Place the self-tapping screw provided through the round metal ring
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.
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.
Locate the rectangular amber side marker lights attached to the
frame. Route the wire harness from the light out the rear of the
tongue. Attach the light to the side of the tongue with the No. 10 x
¾” screw provided. Repeat on the other light.
Locate the wire harness shipped in the hardware bag. Unwind and
insert the two plugs that mate to the frame harness down, then out
the rear of the tongue. Mate the plugs on the end of the wires from
the side marker lights just installed with the single plugs on the
wires at the rear of the tongue harness.

ACTUATOR
Attach the actuator to the tongue with the ½” x 4” hex bolts provided. Secure with ½” flange lock nuts. Tighten.
Thread the one end of the tongue brake line into the port on the
rear of the actuator. Tighten.
SAFETY CHAINS
Locate the 1/2”x 5” hex bolt. Slip the bolt through a ½” flat washer,
then place through the last link of one of the safety chains. Insert
the bolt into the hole provided in the drop portion of the tongue until
it comes out the hole on the other side of the drop tongue. Place
on a second safety chain, a ½” flat washer, and secure with a ½”
flange lock nut. Tighten.

WINCH POST
Locate the winch post and position it on the tongue. Place the ½”
x 3 9/16” x 6” U-bolts up around the tongue, align the legs of the
U-bolts with the holes in the winch post base and insert. Secure the
U-bolts in place using ½” flange lock nuts. Tighten only enough to
secure in place because they will have to be moved again for final
adjustment when the boat is placed on the trailer.
Locate the winch handle. Press the retainer clip on the end of the
winch handle so it can be slipped onto the drive shaft. Release
clip once the handle is fully on the drive shaft. Note that the winch
handle should be removed during transport to eliminate the possibility of loosing it.

ROCKER ARMS
Locate the rocker arms (Ref. No. 7 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.
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.
Midwest Industries, Inc. Ida Grove, IA 51445 800.859.3028 www.shorelandr.com 0003482

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.
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.
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. 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 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 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.
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.
Thread the brake line fitting into the brake line hose.
Note: Wire harnesses and brake lines will need care when moving
the axle assembly.
Tighten.
REAR RB SUPPORT SYSTEM
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.
Place the boat on the trailer so that the transom is located 1-2”
from the rear of the bunks. This gives you maximum support on
the transom.
The complete brake system including the axle MUST be re-bled to
ensure that all air has been removed from the brake system.
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
Midwest Industries, Inc. Ida Grove, IA 51445 800.859.3028 www.shorelandr.com 0003482

Page 9
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.
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.
Position the RB bunk assemblies so they are far enough apart to
give your boat stability while transporting. When the desired width
is achieved, move the RB bunk assemblies so that they are just to
the outside of a strake.
Remove the winch handle during transport to eliminate the possibility of loosing it.
Adjustments are now complete. Double check your boat 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.
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.
The RB bunk assemblies 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 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.
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.
Tighten in position.
WINCH POST
Once all other adjustments are complete, the winch post can be
adjusted. Slide the winch post backward on the tongue until the
bow stop roller comes in contact with the boat. This bow roller must
be positioned directly above the bow eye to prevent your boat from
moving forward in the event of a sudden stop. The bow roller assembly can be moved up or down by loosening the three ½” bolt
securing it to the winch post weldment. Slide the winch and bow
stop roller assembly up or down until the bow roller is just above the
bow eye. Hook the winch strap into the bow eye so it passes under
the bow roller. Tighten the strap with the winch to hold the assembly
in position while the bolts loosened to adjust are retightened.
Tighten the bolts securing the winch post assembly to the tongue.
Hook the bow eye safety chain into the bow eye of the boat. This
is just another level of protection to keep your boat and trailer together as one unit.
