Genuine Bentley Bentayga W12 Crankshaft Pulley (Harmonic Balancer) - 07P105243E
Description
Restore engine smoothness and protect your crankshaft with the Genuine 07P105243E Crankshaft Pulley.
Known in the US as a Harmonic Balancer, this part is critical for the longevity of the Bentley W12 engine. It features a heavy-duty rubber-to-metal bonded design that absorbs the natural vibrations produced by the crankshaft. When the internal rubber dampener perishes, it can cause the pulley to separate, leading to "thrown" belts, engine vibration, or even catastrophic crankshaft failure.
Topical Authority Specs:
- OEM Part Number: 07P105243E.
- US Terminology: Crankshaft Pulley / Harmonic Balancer.
- Engine Fitment: 6.0L W12 Twin-Turbo (Bentayga, New Gen Continental GT/Flying Spur).
- Construction: Precision-balanced steel with high-temp bonded elastomer dampener.
Why Choose Genuine? A Bentley W12 rotates with incredible force. Aftermarket pulleys often lack the precise weight and balance of the 07P105243E, which can introduce new vibrations that wear out your alternator and A/C compressor bearings prematurely. Stick with the factory-spec balancer to keep your W12 "Bentley-smooth."
Tech Tip:
When replacing the 07P105243E Crankshaft Pulley, the central mounting bolt is a "one-time-use" stretch bolt. Reusing the old bolt can lead to the pulley backing off the crankshaft, which is a common cause of engine bay damage.
