Stronger Tube Used Between Rear Suspension Cylinders And Accumulators{7218,5077,7213}
Usage:
D30C ( 7ZC ),
D35C ( 2GD ),
D35HP ( 3FD ) Trucks
Description of Change: The steel tube which transfers oil to the rear suspension cylinders and accumulators now has a thicker wall. The outside diameter of the new tube has not changed, and no new parts are needed. Due to stress and vibration fatigue, the former pipe could crack and is no longer serviced.
Adaptable To: A new 7U3476 RR Suspension Tube Assembly is a direct replacement for the former 6U2187 Accumulator Pipe Assembly (see illustration). This change is in effect with the D30C (7ZC224), D35C (2GD109), and D35HP (3FD80) Articulated Dump Trucks.
Location of new tube assembly in relation to the rear suspension cylinders and accumulators.
