Product Introduction

Structure

This engine mount cushion is a laminated elastomer-metal composite assembly designed for heavy-duty truck powertrain systems. It features two thick, precision-machined steel mounting plates (top and bottom) with multiple bolt holes for secure chassis and engine attachment, sandwiching a stack of high-performance rubber layers bonded to interleaved steel reinforcement plates. The top plate includes a central recess for precise alignment, and the entire assembly is finished with a matte gray anti-corrosion coating. Labels with part number and production information are affixed for traceability.

Performance

The rubber layers are formulated from high-grade, oil-resistant synthetic rubber, offering exceptional vibration damping, load-bearing capacity, and resistance to aging and abrasion. The interleaved steel plates enhance structural rigidity and load distribution, while the steel mounting plates ensure secure attachment. The assembly operates reliably in temperatures ranging from -40°C to 120°C, resisting degradation from engine oil, chemicals, and UV exposure. It effectively isolates engine vibrations, reducing noise and improving driver comfort, while maintaining the necessary stability for powertrain operation.

Core Function

1. Acts as a critical vibration isolation and load-bearing component between the engine and chassis, absorbing and dampening engine vibrations to improve ride comfort and reduce component fatigue.

2. Provides stable support for the heavy-duty engine, distributing loads evenly and preventing excessive movement or misalignment during operation.

Isolates noise and vibration from the powertrain, reducing driver fatigue and improving overall vehicle refinement.

Key Features and Benefits of Engine Mount Cushion AZ9725520276

This engine mounting cushion does far more than simply hold your engine in place. Here’s why it stands out:

• Superior Vibration Damping: Engineered with high-density rubber compound that effectively absorbs and isolates engine vibrations, preventing them from transferring to the truck frame and cabin.
• Noise Reduction: By cushioning the engine’s oscillations, this mount significantly reduces operational noise, creating a more comfortable driving environment for long-haul operators.
• Precision OEM Fit: Manufactured to match the exact dimensions and mounting points of the original Sinotruk AZ9725520276 specification, ensuring hassle-free bolt-on installation.
• Extended Service Life: Resistant to oil, heat, and fatigue cracking, this cushion maintains its elasticity and structural integrity even under extreme operating conditions.
• Chassis Protection: Acts as a shock buffer that prevents metal-to-metal contact, protecting both the engine block and chassis mounting brackets from stress fractures.
• Cost-Effective Maintenance: Timely replacement of worn engine mounts prevents costly secondary damage to exhaust systems, hoses, and wiring harnesses.

In short, this engine mount cushion keeps your Sinotruk running smoothly, quietly, and reliably — mile after mile.

Application Scenarios

The Engine Mount Cushion AZ9725520276 is designed specifically for the following applications:

• Compatible Vehicles: Sinotruk HOWO heavy-duty trucks and related CNHTC (China National Heavy Duty Truck Corporation) models equipped with the corresponding engine platform.
• Function: Engine foot pad (engine mounting cushion) — positioned between the engine and the chassis frame.
• Primary Role: Vibration damping, noise reduction, and shock absorption to buffer engine oscillations during acceleration, braking, and rough-road operation.
• Ideal For: Fleet maintenance programs, truck repair workshops, and aftermarket parts distributors serving the Sinotruk HOWO segment across Africa, the Middle East, Southeast Asia, and South America.

If your trucks are experiencing excessive cabin vibration, unusual engine movement, or increased noise levels, a worn engine mount cushion is often the culprit. Replacing it promptly restores ride comfort and prevents cascading damage to adjacent components.

Frequently Asked Questions (FAQ)

What does the Engine Mount Cushion AZ9725520276 actually do?

This engine mount cushion sits between the engine and the chassis frame of your Sinotruk HOWO truck. Its primary job is to absorb and dampen the vibrations generated by the engine during operation. Without it, those vibrations would transfer directly into the frame and cabin, causing excessive noise, driver fatigue, and accelerated wear on surrounding components.

How do I know when my engine mount cushion needs replacement?

Common signs of a worn or failed engine mount cushion include increased vibration felt in the cabin, visible engine movement when accelerating or braking, unusual clunking noises from the engine bay, and cracked or deteriorated rubber on the existing mount. If you notice any of these symptoms, it’s time to inspect and replace the cushion.

Is this engine mount cushion an exact fit for my Sinotruk HOWO truck?

Yes. The AZ9725520276 engine mount cushion is manufactured to OEM specifications, meaning it matches the original part’s dimensions, bolt pattern, and load-bearing characteristics. However, we always recommend cross-referencing the part number with your vehicle’s documentation to confirm compatibility.

What material is the Engine Mount Cushion AZ9725520276 made from?

It features a high-density natural rubber bonded to a metal mounting bracket. The rubber provides the vibration-absorbing properties, while the metal bracket ensures secure attachment to both the engine and chassis. This combination offers excellent durability against heat, oil exposure, and mechanical fatigue.

Can a damaged engine mount cushion cause other problems in my truck?

Absolutely. A failed engine mount allows the engine to shift and move excessively, which can strain exhaust connections, stretch or break coolant hoses, damage wiring harnesses, and even cause misalignment with the transmission. Replacing a worn mount promptly is far less expensive than repairing the secondary damage it can cause.

Do you offer bulk pricing for fleet orders?

Yes, we do. Mettlead provides competitive tiered pricing for bulk and fleet-level orders. The more you order, the better your per-unit cost. Simply contact us with your required quantity for a custom quotation.
