4.10 Single Point Suspension Clamp Load Cell Mount Installation
The Model 117667 Clamp Load Cell Kit is designed for installation to a 4.00” diameter trunnion tube (dead axle)
of a single point trailer suspension.
Model 117667 load cell assembly consists of:
• One 117666 Heavy Duty Load Cell (2 per kit)
• One 116436 Bearing Plate (2 per kit)
• Two 114342 load cell tie-down bolts, 1-1/8” -12UNF x 3.25”L, Grade 8 (4 per kit)
• Two 114256 Washers, 1-1/8”, F436 (4 per kit)
• One Lower Clamp Unit (2 per kit)
• One Upper Clamp Unit (2 per kit)
• Hardware
Two load cell assemblies are required per single point trunnion suspension installation.
BASE MOUNTING PLATES REQUIRED
Two flat steel plates of 1018 CRS, typically ¾” thick with minimum dimensions of 4.50” x 17.50”, with clean,
smooth surfaces on both top and bottom.
Important
Note: The actual size of this mounting plate will be determined by the installer, based on the dimensions of the underside
trailer mounting surface dimensions, which could require larger plate. The above dimensions are minimum size for the
load cell bearing plate used.
OTHER MATERIALS NORMALLY USED:
• A bubble level
• Serviceable thread locker
• Torque wrench and cheater bar capable of ensuring 1000 lb/ft.
• Safety Blocks or Stands
• Metal Primer or Automotive Underbody Sealer
• Allen wrench (for the cable clamp)
• Cable Ties
When installing clamp load cells to the single point suspension it is critically important that the factory
alignment of the suspension be maintained. The installer must ensure that suspension alignment
requirements are met to the manufacturer's specifications. Contact the trailer manufacturer if necessary.
Rice Lake Weighing Systems assumes no responsibility for trailer or suspension alignment problems
which might occur.
