When installing the Equa-Flex Equalizer into the
center frame hanger, the Equa-Flex Equalizer label should
be facing out.
1.
Install the equalizer bolt through the frame hanger
outside plate, the top most bronze equalizer bushing, and
through the frame hanger inside plate.
2.
Use a hammer or a piece of steel tube (for bolts with
a grease fitting) and drive the bolt into the frame hanger
outside plate, until the bolt head is seated against the
hanger surface.

THE TRAILER MUST BE SUPPORTED PER

3.
Both the shackle bolts and equalizer bolt must be
installed from the outside-in towards the center of the
trailer chassis. This ensures that the bolt threads do not
interfere with any other assemblies. This applies to bolts
with or without grease fittings.
4.
Thread a nut onto the exposed equalizer bolt thread until
the nut seats against the hanger. Torque the nut until it
bottoms out on the bolt shoulder at 30-50 ft-lbs.
5.
Place the axles into the normal operating position.
6.
Attach the new shackle links with shackle bolts and
mounting nuts.
7.
Torque the nuts until they bottom out on the bolt
shoulder at 30-50 ft-lbs.
8.
Repeat steps 1-7 for the opposite side of the trailer.
NOTE:
If using the triple axle greaseable bolts with grease
fittings, use any multi-purpose grease marked with the
NLGI code of GC-LB.
