Upper Assembly:
1: Place the upper button bearing assembly to the underside of the upper flexure assembly.
With the wear plate correctly orientated as to its corner countersunk holes, apply grease and
install the four ¼-20 x ½” flat-head screws through the wear plate, flexure assembly, and into
the bearing assembly.
2: Position the flexure and bearing assembly on the top of the load cell with the three holes
at the edge of the flexure facing the three holes in the mounting block at the upper rear of the
support assembly.
3: Position the mounting block bar, and loosely install three ½-13 x 1-1/4” hex bolts and lock
washers to hold the flexure assembly and bar into position. Apply grease to the bolt threads.
2-O: Adjusting Elevation:
1: With all load cell support assemblies installed, assembled, and placed upon the load cell
base plates as described in the preceding pages, prepare to carefully lower the weighbridge
onto each load cell support assembly one at a time with a hydraulic jack of sufficient capacity.
Starting with an end section, lower the weighbridge onto the load cell support assemblies at
that section one at a time.

Ensure that the top bearing plate centers on the wear plate at each flexure, moving the
entire assembled load cell support assembly on the base plate as required to accomplish this
centering. Ensure the hex bolts that connect the top flexure plate to the support assembly
stand are inserted but not completely tightened before lowering the weighbridge onto the load
cell support assembly. Continue until the weighbridge is completely supported by the load-
cells.
DO NOT REMOVE THE SUPPORTING BLOCKING AND CRIBBING AT THIS TIME.
LEAVE THEM IN PLACE CLOSE TO THE MAIN BEAMS TO SERVE AS A SAFETY PIER.
