Detailed Description

The LuK LFW473 flywheel is designed for clutch replacement on 2008-2012 Honda Accord and 2009-2014 Acura TSX applications. As a critical mating surface in the clutch system, the flywheel must remain flat and consistent to support proper clutch engagement and release. This OE-spec flywheel helps replace worn, heat-checked, or uneven original parts with a new component built to the correct dimensions.

This part cross-references EXEDY OEM HCF001 for the same application. It is also associated with aftermarket interchange references 22100R40003 and 4160310100, as well as Perfection 50-2877. The LuK LFW473 is a practical choice when servicing a Honda Accord or Acura TSX clutch system and replacing the flywheel at the same time.

What It Helps Address

• Clutch chatter caused by an uneven flywheel surface
• Judder or vibration during takeoff
• Slipping or inconsistent clutch engagement from heat damage
• Noise or drivability issues related to worn flywheel teeth or mounting surfaces
• Repeat clutch service caused by reusing a damaged flywheel

Installation Notes and Tips

Inspect the clutch, release components, and rear main seal during flywheel replacement. Confirm the flywheel diameter, tooth count, and step height match the original part before installation. Proper torque procedures and clean mating surfaces are important for correct clutch operation on Honda Accord and Acura TSX manual transmission service.

Quality Assurance

LuK manufactures this flywheel to OE specifications, with attention to the ring gear and dowel pin details required for accurate fit and function. The LFW473 is a new component, not remanufactured, which supports consistent installation quality for Acura TSX and Honda Accord clutch repairs.
