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. Re-
move 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.
