Assemble the preassembled saddles, load cushions and frame hangers to the chassis frame. Install mounting bolts, lock washers and nuts. f. Tighten mounting bolt nuts to specified torque. (See SPECIFICATIONS.) g. Tighten drive pin nuts to specified torque. (See SPECIFICATIONS.) 2. Assemble cross tube and equalizer beams to axle assemblies, Figures 14 and 15. CAUTION -- WHEN ASSEMBLING SUSPENSION, EQUALIZER BEAM AND MOUNTING NUTS, AND EQUALIZER BEAM SADDLE CAP MOUNTING NUTS SHOULD HAVE FINAL TORQUE APPLIED WITH WHEELS OF VEHICLE ON GROUND. WARNING -- THREE TYPES OF EQUALIZER BEAMS ARE UTILIZED IN THE MANUFACTURING OF INTERNATIONAL TRUCKS EQUIPPED WITH EQUALIZER BEAM SUSPENSIONS.ALTHOUGH THE APPEARANCE OF THE EQUALIZER BEAMS IS SIMILAR, THERE IS A SUBSTANTIAL DIFFERENCE IN THE MATERIAL OF WHICH THEY ARE MANUFACTURED. THE MATERIALS OF THE EQUALIZER BEAMS INVOLVED ARE ALUMINUM, CAST STEEL AND NODULAR IRON.ALUMINUM AND CAST STEEL EQUALIZER BEAMS ARE MANUFACTURED SUCH THAT THEY CAN BE STRESSED IN EITHER DIRECTION. NODULAR IRON EQUALIZER BEAMS ARE MANUFACATURED SUCH THAT THEY CAN BE STRESSED IN ONE DIRECTION ONLY. THUS IT IS IMPERATIVE THAT NODULAR IRON EQUALIZER BEAMS BE INSTALLED WITH THE CORRECT SIDE UP. TO AID IN IDENTIFICATION AND FACILITATE INSTALLATION OF NODULAR IRON BEAMS, AN ARROW AND THE WORD UP HAVE BEEN MOLDED ON THE SIDE OF NODULAR IRON BEAMS. ALSO, REINFORCING GATE PADS HAVE BEEN DESIGNED INTO EACH END AND MIDDLE OF THE TOP SIDE OF NODULAR IRON BEAMS. NODULAR IRON EQUALIZER BEAMS MUST BE INSTALLED WITH GATE PADS ON TOP SIDE OF BEAM AND THE ARROW MOLDED ON THE BEAM SIDE POINTING UPWARD. Figure 15 - Rubber Cushion Type Suspension CTS-4169 - Page 11
