Remove the small parts from the frame by cutting the
bands. Remove the bolt bag and sort all nuts and bolts by
size.
Rocker Boxes:
Align the center hole of the 6239210, rocker arm, with the
center hole of the spring bracket. Secure with a 3/4” X 4-1/
2” hex bolt from the outside-in and tighten with a 3/4” hex
lock nut with grease zerk down.
Axles:
Fasten the springs to the axles with the 1/2” axle u-bolts,
spring plate and 1/2” flange lock nuts. NOTE: Make
certain that hook end of the springs point in the same
direction - to the rear of the trailer - on both axles! For the
rear spring and axle place a S-3207 galvanized spring
bracket bushing in the rear of the spring bracket. Insert a
9/16” X 3-1/4” hex bolt through the bracket from the
outside-in and tighten with a 9/16” hex lock nut. Slide the
end of the hook spring over the bushing; raise the front of
the spring and fasten with a 9/16” X 3-1/4” hex bolt and 9/
16” hex lock nut.
For installation of the front spring and axle - repeat the
above procedure, however, place the bushing in the rocker
box in the hook end of the spring. Insert the 9/16” hex
bolts and secure with 9/16” hex lock nuts.
Mount the tires and rims using 80-90 ft. lbs. torque on the
lug nuts.
Tongue:
Slip the tongue into the front frame cap of the frame. Line
up the holes; fasten the tongue in the frame with a 1/2” X
4” hex bolt and 1/2 flange lock nut at the front of the frame
cap. Secure the tongue plate cover (Ref.#80) and the rear
of the tongue with a 1/2” X 1-1/2” hex bolt and 1/2” hex
lock nut. Pull the wire harness through the hole in the top
of the tongue, then back out through the tongue. Place the
rubber grommet in the hole. Plug the tongue harness into
the frame harness.
Actuator & Safety Chain:
Slide the actuator (Ref.#110) into the actuator housing unit
(Ref.#109) and secure with two pins and snap rings
provided with the actuator. Secure the actuator-housing
unit to the front of the tongue using three (3) 1/2” X 4” hex
bolts and 1/2” flange lock nuts. Using a 1/2” X 5” hex bolt
on lower right mounting hole on tongue, secure the safety
chain. Place a 1/2” flat washer on 1/2” X 5” hex bolt
followed by one safety chain and insert into actuator
housing unit and tongue. Place the second safety chain on
the bolt followed by a 1/2” flat washer and 1/2” flange lock
nut. Tighten.

Refer to the brake manual for service and maintenance.
Winch Post:
Install the winch post on the tongue in the desired position
and secure with three (3) each 1/2” X 4” carriage bolts and
1/2” flange lock nuts. Install the winch handle on the winch
shaft.
Bunk Assembly:
Mount the 2X6 bunk over the rear bunk channel and
secure the bunk brackets to the support channel with 3/8”
X 1” hex bolts and 3/8” flange lock nuts. Tighten as far as
possible but still allow the bunk to pivot side to side.
