2 Introduction This Equalizing Beam and Components Selection Guide is intended to aid in the proper identification for aftermarket replacement of originally equipped equalizing beam and other components. It helps determine the proper and complete beam assembly part numbers, end bushing service kit numbers and center bushing requirements. Important Notes Equalizing beams are available for suspensions with 34,000 pound to 120,000 pound capacity with axle spacing of -72½". All equalizing beam assemblies include end bushings and center bushings (if equipped). Hendrickson DOES NOT supply equalizing beam assemblies without bushings. Equalizing beam length is measured from the centerline of one end hub to the centerline of the other end hub. equalizing beam Hendrickson introduced the improvement from a forged/cast equalizing beam to a fabricated beam design for up to 46,000 pound capacity between August 1999 and March In February 2008 the fabricated beam was introduced for 52,000 pound and up capacity vehicles. The fabricated beam is completely interchangeable with the discontinued forged beam. Center bushing Part Number ALWAYS REQUIRES transverse torque rods. When using the fabricated style beams, the entire beam assembly must be replaced when converting from a rubber center bushing to a bronze center bushing to accommodate for the grease fitting and channel installation. To convert from rubber center bushings to bronze center bushings, contact Hendrickson Truck Parts. End bushings Both shim and non-shim type bar pin end bushings are completely interchangeable with the rotating bar pin end bushings. Once pressed into the beam, the pins can be rotated to the correct angle for a perfect installation. The bushing pins become fixed at the required angle when the installation is properly completed. It helps save time and labor costs by eliminating re-work from incorrectly installed bushings. No special tools are required to rotate the bushing

3 FABRICATED BEAM ASSEMBLY ORIENTATION IT IS IMPORTANT THAT THE ORIENTATION OF THE BEAM BE IN THE UPRIGHT POSITION. A DECAL MAY BE AFFIXED TO THE TOP OF BEAM TO ASSIST IN ASSEMBLY AND TO VERIFY ORIENTATION. FAILURE TO INSTALL BEAM PROPERLY MAY RESULT IN LOSS OF VEHICLE CONTROL AND POSSIBLE PERSONAL INJURY OR PROPERTY DAMAGE
