Detailed Description

LuK LFW423 is a clutch flywheel made for drivers servicing Mini manual transmission systems that require a precise mating surface for the clutch assembly. The flywheel diameter, inner diameter, step height, and 133-tooth ring gear are engineered to match OE requirements, helping maintain proper clutch operation and consistent engagement. This part cross-references Dayco 88423 for the same application. It is a practical replacement choice for Mini Cooper, Mini Cooper Countryman, and Mini Cooper Paceman models where a new flywheel is preferred over resurfacing.

Compatible With 2007-2015 Mini Cooper, 2011 and 2013-2016 Mini Cooper Countryman, and 2013-2016 Mini Cooper Paceman. Part number LFW423 is also referenced by 4160288100, 11227561765, and DMF91174.

What It Helps Address

• Uneven or worn clutch contact surface
• Clutch chatter during engagement
• Vibration caused by flywheel surface wear
• Service needs after clutch replacement
• OE-spec replacement requirements for Mini manual transmission repair

Installation Notes and Tips

Inspect the clutch assembly, pilot components, and related hardware before installation. Confirm flywheel diameter, tooth count, and step height against the original part before assembly. For best results, replace the flywheel during clutch service rather than resurfacing a worn unit when OE-style replacement is preferred. Verify vehicle application by year, model, and transmission configuration before ordering.

Quality Assurance

LuK manufactures this flywheel to OE specifications as a new component, not a remanufactured part. The design follows original equipment requirements for fit and function, including the ring gear and dowel pin details used in the application.
