ROCKER ARMS
Locate the rocker arms (Ref. No. 1 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. Insert a
3/4” x 4-1/2” hex bolt from the outside in and secure in
place with 3/4” 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. 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
Locate line clamps and 1/4” self tapping screws
provided in the kit. Thread the hose into the hole on the
bottom of the brass block on the right brake calipers.
Form the hose so that it can be placed in a clip and
attached to the spring plate with a #10-32 X1 machine
screw, washers and a 10-32 hex nut to keep it up in
place under the leaf springs.
Route the hose 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.
Remove the plastic plug from the port in the brass
block on the left brake caliper. Thread the brake hose
fitting into this port place in a clip and attached to the
spring plate with #10-32 X1 machine screw, washers
and a 10-32 hex nut to hold the hose in position
making sure that it does not rub or touch the spring.
Tighten all fittings.
Repeat this process on the second axle.
