HOWO T7H TRUCK MAN MC11 MAN MC13 Engine Rear Rubber Mount WG9925590360 FROM SINOTRUK COMPANY
FUNCTION
1. Rear Engine Support and Mounting: Supports the weight and torque generated at the rear of the engine, securely anchoring it to the vehicle frame.
2. Vibration Damping and Cushioning: Absorbs vibrations, shocks, and noise produced during engine operation, preventing their direct transmission to the vehicle frame and cabin.
3. Vibration and Noise Isolation: Utilizes highly elastic rubber materials to effectively reduce the transmission of engine vibrations to the vehicle body, thereby enhancing driving comfort.
4. Protection of Engine and Related Components: Minimizes fatigue damage to the engine caused by vibration, extending the service life of the engine, transmission, mounting system, and other associated components.
5. Adaptation to Dynamic Conditions: Accommodates the engine's fore-and-aft movement and torque reaction forces during vehicle acceleration, braking, uphill climbs, and downhill descents, thereby maintaining engine position stability.
Working Principle
The rear engine rubber mount consists of a high-strength rubber block and a steel bracket. Utilizing its elastic properties, the rubber block absorbs vibrational energy from the engine in the vertical, lateral, and longitudinal directions, converting the majority of this vibration into thermal energy to be dissipated. Simultaneously, it transmits the residual forces to the vehicle frame via the steel bracket, thereby fulfilling the dual function of "support and vibration damping."
Advantages
| Actual Application Effects | Specific Performance (for HOWO / SITRAK Heavy Trucks with MC11/MC13 Engine) |
|---|---|
| Significant improvement in driving comfort | Greatly reduces vibration and noise inside the cab, significantly lowering driver fatigue during long-haul trips and providing a more comfortable ride. |
| Improved vehicle reliability | Effectively protects the engine, gearbox, and chassis components, reducing issues such as bolt loosening and pipeline rupture caused by vibration, thereby extending component service life. |
| Adaptation to heavy-load and harsh conditions | Maintains excellent damping performance and structural strength under high-intensity operations such as full-load transport, mining, and construction; resistant to aging and cracking. |
| Extended maintenance intervals | High-quality oil-resistant, high-temperature-resistant, and aging-resistant rubber material effectively reduces the frequency of engine mount replacement and lowers maintenance costs. |
| Enhanced driving safety | Keeps the engine position stable, preventing safety hazards such as engine displacement, oil pipe/wiring harness stretching, or power interruption caused by mount failure. |

Maintenance Recommendations
| Maintenance Item | Recommended Interval | Specific Actions |
|---|---|---|
| Visual Inspection (Cracks, Aging, Deformation) | Every 10,000 km or monthly | Visually check the rubber block for cracks, hardening, debonding, or oil contamination. Inspect the steel bracket for rust or deformation. |
| Bolt Tightening Check | Every 20,000 km | Check and re-torque all mounting bolts to ensure they are not loose. |
| Vibration and Noise Monitoring | Every 30,000 km or when abnormal vibration/noise is noticed | Pay attention to increased engine vibration or cab noise while driving. Use diagnostic tools if necessary. |
| Complete Suspension System Inspection | Every 50,000 km | Inspect the front engine mounts, transmission mounts, etc., to evaluate the overall condition of the mounting system. |
| Replacement Interval | Every 80,000–150,000 km or when damage appears | Replace aged mounts according to actual operating conditions (shorten interval for heavy-load or mining conditions). |
