Brand New Rear Engine Bearer WG9725592131 for Heavy Truck Sinotruk Shacman Faw Foton Beiben Engine rear support / Rear engine mount / Rear wedge bearing assembly

The WG9725592131 Rear Engine Support Assembly, commonly known as the Rear Engine Mount, Engine Rear Foot Pad, or Wedge Block Bearing, is a critical vibration-isolating component in the powertrain system of SINOTRUK (China National Heavy Duty Truck Group) HOWO series heavy-duty commercial vehicles. This high-strength composite mount connects the rear end of the engine to the chassis frame, providing both structural support and dynamic damping of engine vibrations, torque reaction forces, and operational shocks.

Designed specifically for HOWO A7, T7H, TX, NX, and SITRAK models equipped with Weichai WD615, WD10, WD12 engines, this wedge-shaped rubber-metal assembly plays a vital role in:

Reducing NVH (Noise, Vibration, Harshness) transmitted into the cab
Preventing excessive engine movement during acceleration and braking
Protecting transmission, exhaust, and drivetrain components from misalignment damage
Manufactured using high-temperature vulcanization technology, it combines a multi-layer steel-reinforced core with high-damping natural rubber (NR), delivering excellent fatigue resistance, anti-settlement performance, and long-term durability under full-load conditions.
