ROCKER ARMS

Locate the rocker arms (Ref. No. 7 of  Detail A in Diagram D). Note 

that the center bushing has a grease zerk in it. Position the rocker 

arms 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  ac-

cesible for servicing when needed.

SPRINGS

Position the axles so they are properly aligned with the trailer. Posi-

tion 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.
