nut. Place a second 3/8” x 4” carriage bolt down through the hole in
the rear of the tongue and the front cross member. Place on a 3/8”
flange lock nut. Tighten.
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 inside either the side frames of
the trailer or else 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 D. 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.
Locate the bow eye safety chain in the hardware box. Place a 3/8”
x 1” carriage bolt into the square hole located in the small winch
bracket as shown in Diagram D. The head of the bolt is to be on the
top of the bracket. Place the chain over the bolt just installed on the
bottom side of the small winch bracket. Secure to the small winch
bracket with a 3/8” flat washer and flange lock nut. Tighten.
Axle and 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 as shown in Diagram D. Drop two (2) 3/8” x 2-3/16” x 2” 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 as-
sembly 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 lock nuts.
Tire And Wheel Assemblies
Mount the tire and wheel assemblies using the 1/2” fine threaded ta-
pered lug nuts provided. Tighten to 80-90 ft/lb. of torque using the rota-
tion pattern as shown in the ShoreLandr’s Owners Manual. Re-torque
the lug nuts after 50 miles of driving and then periodically thereafter.
Assembly is now complete and ready to be adjusted to fit the boat that
it will carry.
Bunk Assemblies
Locate the fishing series bunk brackets supplied in the hardware
box. Note that there are two right and two left hand brackets. Refer
to Diagram A for the proper placement of the right and left hand
brackets.
Place a 3/8” x 3-7/16” x 2-1/2” U-bolt over the center cross member
on the left side as shown with the legs of the U-bolt pointing to the
front of the trailer. Place one of the left fishing series bunk brackets
over the U-bolt just installed, then place on a 3/8” flat washer, 3/8”
lock washer and hex nut on each leg of the U-bolt. Hand tighten
for now because they will have to be re-adjusted when the boat is
placed on the trailer. Repeat this process on the remaining left fish-
ing series bunk bracket placing it on the rear cross member.
Locate the 2 x 4 carpeted bunk assemblies. Note that they are
pre-assembled. Position it as shown in Detail A so that the tie down
bracket is located to the rear of the trailer.
Align the hole in the 2 x 4 bunk bracket already mounted to the
bunk with the holes in the left fishing series bunk brackets just in-
stalled. Attach the two together with a 3/8” x 1” hex bolt and flange
lock nut. Repeat the above process on the rear of the bunk. Tighten
the bolts just installed but do not over tighten because the bunks
must be able to rotate to conform to the boat bottom when it is
placed on the trailer.
Repeat the above process on the bunk on the right side of the
trailer. The bunk assembly is now complete but may need to be
adjusted once the boat is placed on the trailer.
Keel Roller Installation
Remove the keel roller assembly from the hardware box. Position it
on the back side of the front cross member of the frame as shown
in Diagram A. Attach it to the cross member by placing a 1/2” star
washer on a 1/2” x 1-1/4” hex bolt. Align the slot in the keel roll-
er bracket with the hole provided in the cross member. Insert the
bolt into the hole and attach to the cross member with a 1/2” lock
washer and hex nut. Repeat this process on the second bolt used
to attach the keel roller assembly to the cross member.
The keel roller assembly can be left loose until the boat is placed on
the trailer for final adjustment.
