Note
Note
Shims are provided to support body off of chassis rails in order to prevent final installation from pre-loading
the hinge bar. If the installer can ensure hinge bar will have free movement in final installation, then shims may
not be required.
1. Remove old bushings with plasma cutter or torch. The installation of new bushings requires precise
alignment to ensure body remains in previous operating position even if bushing/hinge bar size increases in
diameter.
2. Install chassis bushings first. Use hinge bar for alignment and for tack welding bushings in place. Then
remove hinge bar for final welding of bushings. Tack welds for bushings should be strong enough to
prevent any possible movement of bushing after hinge bar is removed for final welding of the bushing.
3. After chassis bushings completed, go to hinge plate bushings for removal and replacement with new
bushings. Again use the hinge bar for alignment, tack weld hinge plate bushings firmly in place, remove
hinge bar and complete final welding of the bushings.
4. Maintain 1/16" (0.0625 inch) clearance between chassis and hinge plate bushings. Install bolts and lock
nuts to hinge bar/bushings.
5. Install lubrication fitting and ensure the hinge bar is adequately lubricated.
Whether hinge bar connector faces outwards or inwards (inwards is preferable) the "UP" notation stamped on
the end of the hinge bar must always be on the topside of the hinge bar in normal rest position.
