FINAL ASSEMBLY INSTRUCTIONS
Remove the hardware bag from the frame, remove parts and sort
by size.
B-SERIES BUNK ASSEMBLY
(See Diagram A, Detail C)
Locate two of the bunk support pivots and place one on each end of
one of the bunk equalizer arms attached to the rear cross member.
Position so the concave in the bunk support pivot is downward as
shown in Detail C, then align the holes in the bunk support pivot
with those in the equalizer arm.
Locate one of the carpeted bunks. Note that one end of the bunk
has two galvanized plates with U-bolts extending below. Align the
legs of the U-bolts with the holes in the bunk support pivots, then in-
sert into the holes in the bunk support pivot and the equalizer arm.
Secure the U-bolt in place by sliding a spacer bushing on one leg
of the U-bolt, then a ½” flat washer and ½” flange lock nut. Repeat
on the other leg of the U-bolt. Repeat on the other U-bolt on the
opposite end of the equalizer arm. Tighten the nut until it is securely
against the spacer and flat washer.
Place the front end of the bunk into the bunk bracket on the top
of the adjustable bunk bracket located on the front cross member.
Secure the bunk in the bracket using two No. 10 screws.
Repeat the above process on the bunk on the other side of the
trailer.

TONGUE
The tongue is shipped separate of the frame. Locate the appropri-
ate 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 1-
1/2” 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 else 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 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.
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
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 pos-
sibility 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 ac-
cesible for servicing when needed.
SPRINGS
Position the axles so they are properly aligned with the trailer. Posi-
tion 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.
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. 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 U-
bolts 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 cali-
per. 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 com-
ing 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 Brake Manual.
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 poten-
tial 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 be-
cause 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. On a bunk trailer, the transom of the
boat should be within 1-2” of the end of the bunk. 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 accom-
plished by removing the pivot bolt on 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 re-
moved. Tighten.
The wire harness for the three-light identification light must be re-
positioned where it comes from the side frame to the rear pivot 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 the outside of a strake that your boat
may have. This will help center your boat and assist when loading.
The bunks need be adjusted up high enough to keep the keel from
resting on the center pads. A minimum of one to two inches clear-
ance is desirable.
FRONT BUNK SUPPORT
The front bunks should be adjusted either in or out so that the bunk
will continue to run just to the outside of the strake of the boat.
Adjust the bunks up so that there is approximately 1-2 inches clear-
ance between the keel of the boat and the center cross member
pad.
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 as-
sembly 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 to-
gether as one unit.
Remove the winch handle during transport to eliminate the possibil-
ity 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.
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.
