Rocker Bogie
Locate the rocker bogie as shown on page 4. Note there is a grease zerk in the center bushing of the rocker bogie. This is necessary so
that it can be serviced in the eld when needed. Position the rocker
bogie into the center mounting channel of the spring bracket. The rocker must be positioned with the hole locations as shown for proper operation. Align the center hole of the rocker 60205 with the hole in the center mounting channel of the spring bracket. Insert a 3/4” x 5-1/2” hex bolt from the outside inward as shown and secure with a hex lock nut. Tighten. Repeat on the other rocker bogie.
the line so that it can be routed down the back side of the axle and then over to the brass block on the calipers.
Remove one of the brass plugs from the port in the brass block on the left brake caliper that best aligns with the routing of the line. Note also that the bolt holding the brass block to the caliper can be loosened so that the brass block can be rotated to better accommodate the angle that the brake line approaches the block
on the caliper. Thread the brake line tting into this port to hold
the line in position making sure that the line does not rub or touch the spring. Re-tighten the bolt in the brass block if it has been loosened to rotate the block.
Springs
Position the axles so they are properly aligned with the trailer, which is the disc brake calipers are on the backside of the axle. Block the
axles so they are approximately 12” above the oor. Drop two 1/2”
x 2-9/16” x 6-1/2” U-bolts down over the axle as shown (See Page
10), then down through the holes in the spring mounting plate that is welded to the axle. Position a spring so that the eye end of the spring is to the front of the trailer. Raise the spring up between the U-bolts, slip on another spring plate and secure with four 1/2” hex lock nuts. Run the nuts up the threads but do not tighten until after the springs are mounted into the trailer frame. Repeat on the other end of this axle, then on the second axle.
Axles
Place the eye of the springs mounted on the rear axle into the rear of the rocker bogies. Align holes and secure in the rocker bogies with a 9/16” x 3-3/4” hex bolt and hex lock nut. Raise the rear of the spring and axle assembly up into the rear spring bracket channel. Place a spring support channel (Ref. # 6) under the spring. Align the holes and place 9/16” x 4-3/4” hex bolt through one side of the spring support channel and one side of the spring bracket channel. Next place a spring bracket bushing on the top side of the spring, (See Detail F) align with the bolt just inserted, then insert the bolt completely through the bushing and the other sides of the spring bracket channel and the spring support channel. When completely inserted, secure with a 9/16” hex lock nut. Place the eye of the springs mounted to the front axle into the front spring bracket chan­nel for the front axle. Secure as above using a 9/16” x 3-3/4” hex bolt and hex lock nut. Raise the rear of the springs up into the front side of the rocker bogies. Raise the springs up and secure by plac­ing under the springs 9/16” x 3-3/4” hex bolts and hex lock nuts. Tighten the bolts just installed.
Tighten all axle U-bolts and spring bolts not tightened at this time.

Brake Line Installation
Open and remove parts from hardware box No. 68140 and sort all items. Locate the long (90’) brake line and straighten out by
uncoiling on the concrete oor while walking on the line as you
uncoil. The line should be made as straight as possible to assist
in mounting to the axle. Locate ve (5) brake line clamps and
1/4” self tapping screws provided in the kit. Hold the line on the backside of the axle and familiarize yourself on how it needs to be formed to connect to the brass blocks on the brake calipers. Form
Route the line down the back side of the axle and secure to the
axle with the ve (5) clamps and self tapping screws. Note that
the axle is pre-drilled for the mounting screws. Route the brake line over to the brass block on the right brake caliper. Remove both plugs on the right caliper block. Thread this end of the brake line into one of the ports on the brass block. Thread the male end of the 13” brake hose into the other port from which the plug was removed and tighten. Position the brass block so that neither the hose nor the brake line will contact or rub the spring. Tighten all ttings. Place the other end of the hose up through the hole pro­vided in the brake line clip bracket. Secure in place with the hose clip provided. Item No. 32 on page 6.
Repeat this process on the second axle using the identical com­ponent parts in the hardware box. Locate the brass tee in box
68140. Thread the male port of the tee into the female end of the brake hose of the front axle. Tighten. 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 enough so that it will reach the port of the tee just threaded into the brake hose. Thread the
brake line tting into the top port of the tee and tighten.
Locate the 40” long brake line tube in box 68140. Thread one end of the line into the remaining port of the tee installed in the previous step. Route the line back to the second axle. Place a coil in the line to use up the excess line and then connect the other end of the line into the hose coming from the second axle. Tighten
both ttings. Note that the coil in the line will absorb the vibration
created during towing.
Bleeding the Brake System
Bleed the brake system as specied in the brake manual. The
bleeding process is necessary to remove ALL air entrapped in the system in order for the brake system to function properly.
http://www.shorelandr.com/pages/o_manual/ AxleBrakeLineServiceBulletin.pdf
All bleeding to the line is to be done through the bleeders on the calipers.
Fill the actuator reservoir with brake uid and bleed the line
per the instructions in the brake manual.
TIRE & RIM ASSEMBLIES
Mount the tire and wheel assemblies using the 1/2” ne 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 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:
Once the boat is positioned on the front roller system, 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 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
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 assembly 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 place on it.
Best towing is achieved when the tongue weight is 5-7% of the total gross load of the complete unit.
To move th e axle assembly, loosen the U-bolts that secure the assembly to the side frames. Move the assembly to the desired location, then re-tighten U-bolts.
NOTE: Brake line and wire harness will need care when moving the assembly.
Rear Support System
Place the boat on the trailer so that the transom is located at the rear of the support system. On an RB bunk trailer, the transom of the boat should be within 1-2” of the end of the bunk. The center of the rear rollers on the roller rack should be approximately 4” from the transom. This gives you maximum support on the transom. The rear pivot is adjustable forward and backward to assist in adjusting the trailer to various length boats. This is ac­complished by removing the pivot bolt that attaches the rear pivot to the side frame and then sliding the assembly to the desired position and re-attaching with the pivot bolt just removed. The
wire harness for the three-light identication light will have to be
rerouted as well.
RB Bunks
Make sure the bunks are positioned far enough apart to give your
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. Tighten in position.
Winch Post
Now that all other adjustments are complete the winch post can be adjusted. Slide the winch post base backward on the tongue until the bow roller comes in contact with the boat. This bow roller needs to be positioned directly above the boat bow eye to prevent your boat from moving forward in the event of a sudden stop. Loosen the three 1/2” hex bolts that clamp the winch holder chan­nel to the winch post. Attach the winch strap into the bow eye and slide the winch holder channel up or down to the desired position as you crank the winch tight. Once the bow roller is located just above the bow eye, tighten the three 1/2” hex bolts that clamp the winch holder channel to the winch post. Tighten the U-bolts that secure the winch post assembly to the tongue. Attach the bow eye safety chain into the bow eye of the boat as well. The chain is another level of protection to keep your boat and trailer together as one unit in the event of an accident. It may also be used to keep your boat on the trailer while loading and unloading at the ramp,especially with a roller trailer.
Adjustments are now complete. Double check your boat for t. If desired t has been achieved, tighten all fasteners that may have
either been left loose or have been loosened to do the adjusting.
Re-check all fasteners on the complete trailer to make sure they are all tight and ready for towing. All fasteners should be periodi­cally check 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.
See your ShoreLand’r Owner’s Guide for further technical infor-
mation regarding your trailer and its components. boat as much stability as possible while transporting. Position the bunks so they are located just to the outside of a strake that your boat may have. This will help center your boat and assist when loading. The bunks need to be adjusted up high enough to keep the keel from resting on the center pads. A minimum of one to two inches of clearance is desirable.
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 Support System
RB and Roller
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 t most boats without needing any further
adjustment.
