HOWO A7 HOWO336 HOWO371 WD615 Engine Front Support 1680 590095
It is a shock-absorbing mounting component with a rubber-metal composite structure, installed between the front of the engine (in front of the cylinder block) and the frame/chassis crossbeam, and together with the rear support (WG9725592131), it forms the engine suspension system.
Function
1. Engine Mounting and Positioning: The front of the engine is securely connected to the vehicle frame, supporting the engine's weight, torque reaction forces, and load. This ensures that the engine remains stable, without shifting or tilting during vehicle operation, maintaining the alignment accuracy of the crankshaft, flywheel housing, and transmission input shaft.
2. Vibration Damping and Isolation:The rubber layer of the front support effectively absorbs and attenuates the high-frequency vibrations and torsional vibrations generated during engine operation.This prevents vibration transmission to the frame, cab, and chassis, significantly reducing overall vehicle noise and driver fatigue.
3. Safety and Security Function:If the front support is damaged or the rubber ages, it can cause the engine to tilt/shift forward, leading to driveshaft vibration, clutch noise, oil leaks, and even safety hazards. As a critical component of the engine mounting system, it directly affects vehicle handling stability and power transmission efficiency.
WD615 series engines (Weichai WD615.47, WD615.69, WD615.87, etc., commonly available in 336/371/375 horsepower configurations)
Often used in conjunction with the rear support AZ9725591020 to form a complete engine mounting system.

Every 100,000-200,000 kilometers or every 6-12 months (in conjunction with regular maintenance), visually inspect the rubber layer at least quarterly for cracks, crazing, bulging, permanent deformation (compression exceeding 5mm), delamination, or signs of aging (rubber hardening, becoming brittle, or darkening in color).
If slight cracking occurs or the mileage reaches 500,000-800,000 kilometers, proactive replacement is recommended (low cost, prevents major repairs).
