- Paving Compactor:
- PS-150B (S/N: 3XR1-UP)
- PS-200B (S/N: 5JR1-UP)
Introduction
This Special Instruction provides information in order to install the new traction control system on the PS-150B Pneumatic Compactor and the PS-200B Pneumatic Compactor. The traction control system routes the hydraulic oil to the drive motors. Hydraulic oil is prevented from moving to the drive motor of the wheel that is spinning. The hydraulic oil will then pass through a flow divider valve which will force the opposite wheel to turn. This Special Instruction has been modified.
Installation Procedure
- Install the parts that are listed in Table 1 on the 120-7067 Propel Pump and Mounting Gp (1). Refer to Illustrations 2,3 and 4.
