ROCKER ARMS
Locate the rocker arms (Ref. No. 6 of Detail A in Dia-
gram D). Note that the center bushing has a grease
zerk in it. Position the rocker arms up into the cen-
ter 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. Tight-
en. Repeat this process on the other rocker arm and
spring bracket. Grease the rocker at this time by ap-
plying 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. Position the brake axle so that the disc brake
calipers are on the back side of the axle. The brake
axle must always be mounted as the rear axle to give
you the best braking possible (See Diagram D.)
There is no right and left to the axle without brakes. It
can be mounted either way.
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. 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 placed. Secure in place with 1/2”
lock nuts. Thread onto the U-bolts but do not tighten
securely until the complete unit is in position on the
trailer. Repeat on the other spring.
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 in other spring
bracket. Position the rear axle under the frame, then
hook the loop of the springs around the bushings just
installed. Note that if the axle is positioned too low
when trying to hook, the loops will not hook around
the bushings.
Raise the front of the springs up so they align with the
rear hole in the axle boogie just installed. Secure in
place with 9/16” x 3-1/4” hex bolts and lock nuts.
Install another spring bracket bushing in the front hole
on the rock arm assemblies. Secure with a 9/16” x 3-
1/4” hex bolt and lock nut. Tighten.
