BUNK BRACKETS AND BUNKS
Locate the bunk brackets. See Detail C. Note that the front bunk
brackets are located on the front of the crossmember while the rear
bunk brackets are located on the rear of the cross member. Choose
a pair of holes for the bunk location. Attach the bunk brackets to the
cross members using 3/8” x 1” carriage bolts, lock washers and hex
nuts. Hand tighten only because they will have to be adjusted when
the boat is placed on the trailer.
Position the bunks so that they are above the bunk brackets just
installed. Note that the mounting brackets attached to the bunks
are not centered on the bunks but are off center 4 inches. They
can be installed either direction. Positioning them so the extra bunk
is to the rear will allow you to put a longer boat on the trailer. This
adjustment may also be critical when trying to establish the correct
tongue weight.
Attach the bunks to the brackets using 3/8” x 1” carriage bolts and
flange lock nuts. Tighten but do not over tighten because the bunks
must be allowed to rotate at this point so they will conform to the
boat when it is placed on the trailer.
FRONT SUPPORT PAD
Install the front support pad to the trailer tongue by placing the legs
of the pad support mounting bracket down over the tongue. Secure
in place by placing two- 3/8” x 4” carriage bolts through the pad
support mounting bracket, one on top of the tongue and the other
on the bottom. See Diagram B. Secure with 3/8” flange lock nuts.
Do not tighten at this point because they will be re-adjusted when
the boat is placed on the trailer.
Connect the tongue wire harness into the side frame harness of
the trailer by matching plugs. Attach the white ground wire of the
tongue harness to the frame using a No. 10 x 3/4” self-tapping
screw provided so that a good ground connection is made between
the frame of the trailer and the tow vehicle. Push all extra wires
used to make the connection back into the tongue. Place a second
rubber grommet into the hole where the wires exit the tongue to
protect them from damage during normal use.
WINCH POST ASSEMBLY
The winch post assembly is pre-assembled and is shipped banded
to the frame. See Diagram C. Place the winch post on the tongue in
the approximate location. Attach to the tongue using three (3) 3/8”
x 4” hex bolts and 3/8” flange lock nuts. It can be left loose until the
boat is placed on the trailer for final adjustment.
Place the winch handle on the drive shaft of the winch by mating
the flat sides of the drive shaft with the punched hole in the winch
handle. Secure the handle to the drive shaft with the 1/2” lock nut
provided. Tighten.
AXLE & WHEEL ASSEMBLY
Locate the axle for the trailer. Note that there isn’t a right or left to
the axle assembly. Place one of the springs on top of the spring pad
welded to the axle. Drop two (2) 3/8” x 2 3/16” x 1-3/4” U-bolts over
the springs and down through the holes in the spring pad. Secure
with 3/8” flange lock nuts. Repeat this process on the other spring
mounting it so that it is oriented on the axle the same as the first
spring.
Slip a spring bushing spacer into the rear of the spring bracket,
align the bushing with the hole in the bracket and secure in position
using a 1/2” x 3” hex bolt and 1/2” flange lock nut. Tighten. Repeat
on the other spring bracket.
Slide the axle assembly under the trailer frame, raise up and slide
the rear of the springs above the bushings just installed. Rotate the
assembly up until the front spring eyes align with the front holes in
the spring bracket. Insert a 9/16” x 3-1/4” hex bolt and secure with
a 9/16” lock nut. Tighten. Tighten the U-bolt attaching the springs
to the axles at this time and any other bolts that may have been left
loose for ease of assembly.
Place the tire and wheel assemblies on the hubs and secure with
the 1/2” tapered lug nuts.
TIRE & WHEEL ASSEMBLIES
Mount the tire and wheel assemblies using the 1/2” fine threaded
tapered lug nuts provided. Tighten to 85-95 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 periodi-
cally thereafter.
