Hendrickson — RS

Description

This walking beam suspension is most often found on cement mixer trucks. The OE rubber load springs are usually found to have taken significant compression set due to their inability to withstand the acid wash used to clean lime off the suspension. The acid attacks and weakens the rubber, compromising its ability to sustain the load. ATRO polyurethane is impervious to chemical attack.

 Tech Tips and Additional Resources

On the RS, ATRO’s load pads are made of a proprietary low rebound (no-bounce) material to absorb shock and limit its transfer to the frame. To accomplish this with rubber, the OE traditionally offers two different part numbers of varying hardness for specific applications. ATRO’s one part number will perform reliably in any application.

  • ATRO center bushings require thrust washers
  • ATRO bushings have free-rotation design
    • Eases installation
    • Automatically zeroes out to ride height

 Wear Items

  • Rubber springs – due to chemical attack causing dry rot and compression set
  • Walking beam bushings – both bar pin end bushings and centers
  • Torque rod/bushings – check all, especially transverse rod

 Key Parts

Torque Rods are availble in any length, or as two-piece rods.
