Bentley Flywheels
Engineered Smoothness: Genuine Bentley Flywheels. The flywheel in a Bentley serves as a critical component in achieving the brand's legendary refinement and effortless power delivery. Positioned between the high-torque W12 or V8 engine and the sophisticated ZF transmission, the flywheel must manage immense rotational forces while dampening vibrations that could compromise cabin comfort. A genuine Bentley flywheel replacement is essential for maintaining the mechanical harmony of the drivetrain. Whether you are addressing a high-mileage service or a complete engine overhaul, utilizing an OEM flywheel ensures that the crankshaft's kinetic energy is stabilized exactly according to the factory specifications of the Crewe engineers.

Technical Specifications and Torque Management Bentley drivetrains are subjected to some of the highest torque loads in the automotive world. Our inventory of genuine flywheels is selected to handle these extreme parameters:
- Dual-Mass Flywheel (DMF) Systems: Most modern Bentley models, including the Continental GT and Flying Spur, utilize advanced dual-mass technology. These units feature internal spring-damper systems that isolate the transmission from engine pulses, ensuring the seamless gear changes Bentley is known for.
- W12 Specific Metallurgy: The flywheels for the 6.0L W12 engine are manufactured from high-grade alloys designed to withstand the unique firing order and thermal output of the twin-turbocharged power unit.
- Ring Gear Precision: Every genuine flywheel features a hardened steel ring gear, ensuring precise and reliable engagement with the starter motor, preventing the "grinding" issues often associated with inferior aftermarket alternatives.
- Balanced Inertia: Each unit is factory-balanced to eliminate harmonic vibrations, protecting the main bearings and ensuring the longevity of the entire rotating assembly.
Reliability for High-Torque Applications. The immense weight and power of a Bentley place extraordinary stress on the drivetrain. A failing or sub-standard flywheel can lead to excessive NVH (Noise, Vibration, Harshness), damage to the transmission input shaft, or even failure of the crankshaft oil seal. By choosing a genuine Bentley flywheel from Masparts, you are investing in a component that has been rigorously tested to handle the "Bentley wave of torque" without compromising the vehicle’s serene driving experience.
The Masparts Advantage:
- VIN-Specific Identification: We verify your chassis number to ensure the correct flywheel weight and bolt pattern, distinguishing between the various generations of the W12, V8, and V8 S engines.
- Specialized Heavy-Duty Freight: Flywheels are heavy, precision-engineered items. We utilize reinforced, vibration-dampening packaging to ensure the friction surface and internal dampers arrive in perfect condition.
- Complete Hardware Solutions: To ensure a professional installation, we can also supply the required OEM stretch bolts, pilot bearings, and specialized seals that should be replaced during a flywheel service.

F.A.Q.
-
Bentley exclusively uses Dual Mass Flywheels (DMF) in modern models to dampen the immense vibrations of their high-torque engines. A Single Mass Flywheel (SMF) is a solid piece of metal; while simpler, installing one in a Bentley would likely cause significant gear noise, cabin vibration, and potential damage to the transmission input shaft.
-
Common symptoms include a distinct chatter or rattling sound when the engine is idling, increased vibration through the floorpan during acceleration, or a pulsing sensation felt through the brake or clutch pedal. If left unaddressed, a failed DMF can eventually prevent the car from starting or cause catastrophic damage to the bellhousing.
-
Yes. Bentley flywheels are secured with high-tensile stretch bolts designed for one-time use only. Reusing old bolts risks them backing out or snapping under the extreme centrifugal forces of the engine, which can lead to total engine and transmission failure.
-
While not always mandatory, it is highly recommended to perform a transmission adaptation or crankshaft sensor relearn using Bentley diagnostic tools. This ensures the engine management system recognizes the new rotational characteristics and optimizes idle stability and gear shift quality.
