Description of Change: A new hydraulic steering mounting group is available for use on 3208 Industrial and Truck Engines. This new mounting group is necessary because the manufacturer of the power steering pump has discontinued the former model "B" pump. They have replaced it with the model "BB" pump. The model "BB" pump requires a different mounting group than the model "B" pump.

Adaptable As: The new 7C7717 Hydraulic Steering Mounting Group is available to mount the model "BB" pump on 3208 Industrial and Truck Engines. The components of the new 7C7717 Hydraulic Steering Mounting Group are shown in the illustration and identified in the chart.
