The tongue comes shipped separately. Locate and install
under the frames front tongue channel and in the channel
welded to the front cross member which will support the rear
of the tongue.

Line the hole in the tongue with the hole in the tongue
channel. Install the 1/2” x 4-1/2” carriage bolt in the front cross
hole and secure with a 1/2” lock nut. Secure the rear of the
tongue to the frame with a 1/2” x 4” hex bolt and lock nut.
Tighten.

Brake Line

Remove the brake line from the brake kit box 68140. Locate
the 58” tongue line. Uncoil the line and insert one end into
the rear of the tongue pushing it forward until the end comes
out of the front of the tongue. Locate the brass brake line
coupling in the hardware box and thread on the rear fitting of
the brake line.

Actuator

Locate the actuator, and position it on the front of the tongue
as shown. Look into the back end of the actuator and locate
the solenoid. Note there is a wire harness coiled around the
round solenoid. Uncoil the wire and plug it into the bullet plug
on the end of the blue wire of the tongue harness. Remove
the plastic plug from the port in the rear of the solenoid Thread
the fitting on the end of the tongue brake line into the port the
of the solenoid. Tighten.

Align the holes in the actuator with the holes in the tongue.
Secure the actuator to the tongue using three (3) 1/2” x 4”
hex bolts and lock nuts. Tighten.

Tongue Wire Harness

Locate the tongue wire harness. Place the end of the wire
harness with the two double plugs into the hole in the top of
the tongue. Pull backwards through the tongue until they can
be fished through the holes in each side of the tongue. Note
that the brown and yellow plug must go to the left side of the
trailer and the brown and green plug must go to the right side
of the trailer.

Plug the tongue wire harness ends into the frame harnesses
by matching colors and ends. Place grommets into all the
wire holes. Push the extra wire provided either into the hole
in the tongue or else remove the grommet in the side frame

Thread the brass coupling provided on the other end of the
brake line just installed. Bend the line coming out the rear of
the tongue 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.

Safety Chains

Mount the safety chains to the front of the tongue by placing
a 1/2” flat washer onto a 1/2” x 5” hex bolt, then insert the bolt
through the last link on one of the safety chains provided.

Winch Post Assembly

Mount the winch post assembly to the tongue in a location
that will best fit your boat. Secure the winch post base
weldment (Ref. 2) to the tongue using (2) 1/2” x 3-9/16’ x 5”
U-bolts and hex lock nuts. Attach the winch post tube
weldment to the base just installed with a 1/2” x 4-1/2” hex
bolt and hex lock nut. Tighten only enough to hold the
assembly in position until the boat is positioned on the trailer.

Snap the winch handle on the winch by compressing the
spring loaded clip incorporated in teh handle. Once in
position, release. Handle is secure.

Refer to Page 6, 7 & 8 for drawings.

Rocker Arms

Locate the rocker arms (Ref. No. 5 of the chassis schematic).
Note that the center bushing has a grease zerk in it. Position
a rocker arm 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 ACCESIBLE FOR SERVICING WHEN NEEDED.

Springs

Position the axles so they are properly aligned with the trailer.
The axles must be positioned so that the disc brake calipers
are on the back side of the axle.

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 on page 6 &

8. Next 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 installed on the bottom side of the axle.
Secure in place with 1/2” lock nuts. Thread the nuts onto the
U-bolts but do not tighten securely until the complete unit is
mounted in position on the trailer. Repeat on the other spring
and the other axle.

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 on other spring bracket.

Position the rear axle under the frame, then hook the hook
loop of the spring around the bushings just installed. Note
that if the axle is positioned too low when trying to hook the
springs on the bushings, the hooks will not hook around the
bushings.

Raise the front of the springs up so they align with the rear
hole in the axle rocker arm. Secure in place with 9/16” x
3-1/4” hex bolts and lock nuts.
Next install another spring bracket bushing in the front hole
on the rock arm assembly. 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.
Then swing the front of the spring up and attach to 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 not tightened at this
time.

Brake Line Installation

Sort all of the items in hardware box No. 68140. Locate the

long (90’) brake line and straighten out by uncoiling on a
concrete floor 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 five (5) 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 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
fitting 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.

Route the line along the back side of the axle and secure to
the axle with the five (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
the other end of the brake line into one of the ports on the
brass block. Thread the 13” brake hose male end into the
other port. Tighten. Position the brass block so that
neither the hose nor the brake line will contact or rub the
spring. Tighten all fittings.

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. 26 in Diagram F.

Repeat this process on the second axle.

Connecting The Two Axles Together and To The Actuator

Locate the brass tee. 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 fitting
into the top port of the tee and tighten.

Locate the 40” brake line tube. 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 any excess line and then connect the other
end of the line into the hose coming from the second axle.
Tighten both fittings. Note that the coil in the line will absorb
the vibration created during towing.

Bleeding the Brake System

Bleed the brake system as specified 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.
