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 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
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 lock nuts.
TIRE & WHEEL ASSEMBLIES
Mount the tire and wheel assemblies using the 1/2” fine threaded
tapered lug nuts provided. Tighten to 80-90 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.
KEEL ROLLER INSTALLATION
Remove the keel roller assemblies from the hardware box. Position
them on the back side of the front two cross members of the frame
as shown in Diagram A. Attach them to the cross members by plac-
ing a 1/2” star washer on a 1/2” x 1-1/4” hex bolt. Align the slot in
the keel roller bracket with the hole provided in the cross member.
Insert the bolt into the slot, then into the hole in the cross member
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.
Repeat the above process on the second keel roller assembly. The
keel roller assemblies can be left loose until the boat is placed on
the trailer for final adjustment.
REAR ROLLER RACKS
Locate the swivel block molded plastic pieces. Slide them onto
the ends of the roller arm weldment as shown. Place the channel
bracket of the roller pin assembly down over the plastic pieces and
secure them together with two (2) 3/8” x 2-3/4” carriage bolts and
3/8” flange lock nuts. Note that one bolt will be on the top side of
the metal tube while the other will be installed so the bolt passes
through the large hole in the metal tube. This will allow the roller
assemblies to rotate on the roller arm weldment to conform to the
boat bottom and still support the load applied to it when the boat
if carried on the trailer. Tighten. Repeat this process on the other
roller arm weldment.
Loosen the two bolts that attach the rear pivot to the trailer side
frames and rotate the rear pivot from it ship position down into its
normal position. Locate the roller rack mounting plates. Place two
of the 3/8” x 2-7/16” x 4” U-bolts into the holes of the plate as shown
and thread on 3/8” flange lock nuts.
Slide the plate with U-bolts just installed onto the rear pivot so that
the roller rack mounting plate is to the front side of the rear pivot
with one U-bolt above the rear pivot and one is below the rear pivot
cross member. Push the U-bolts rearward creating all of the spac-
ing between the inside of the U-bolts and the back side of the rear
pivot cross member. Orient one of the roller arm assemblies so that
the roller pin assemblies tip inward towards the centerline of the
trailer. Drop the mounting tube of the roller arm weldment down
inside the U-bolts and behind the rear pivot cross member. Adjust
the roller arm assemblies up to the desired height to carry your boat
properly and tighten the U-bolts. Assembly is complete.
