Fairbanks 5260 Series Unirail - Manual (Page 15)

The weigh rail should remain in the center of its fixed approaches, and
free to move up and down very slightly on its load cell mounts. The
weigh rail must remain free and unobstructed for proper performance.
Periodic examination and cleaning any debris from its gaps should be
performed regularly. Do not lubricate, grease, or oil any part of the
Unirail.
Loadcells & Weighrail:
1. Load cells for the Unirail are provided in matched pairs, and are
always replaced as a set. Electrical connections are intended to be
individually soldered and insulated, and re-installed in the splice tube.
Note wiring connections before disconnecting them, and removing the
weighrail and loadcells.
2. Mount the replacement load cells to the support bar with existing 1/2-
20 cap screws. Tighten finger tight.
3. Mount the weighrail to the cells using the load cell mounting tool pn
95272. The tool is effectively a threaded stud having a shaft diameter
equal to the hole in the load cell. It centers the rail for optimum
clearence. Equally space the weighrail between the approach rails,
then tighten the load cell support screws.
4. Torque the cell support screws to approximately 75 ft lbs.
5. Remove the Unirail load cell fixure screws supporting the weighrail to
the load cells, and replace them with the special studs. Use the stud
locking compound. Remove the weighrail and torque the studs to
approximately 75 ft lbs.
