Give a new clutch a smooth, flat surface to engage against with the LuK Clutch Flywheel LFW478, a new rigid flywheel and a practical alternative to resurfacing the old one. It is a direct-fit replacement for the 2012-2017 Jeep Wrangler and the 2018 Jeep Wrangler JK with the V6-3.6L engine, and each vehicle uses one.
- Smooth, flat friction surface: Provides the even face that proper clutch operation depends on.
- Built to OE specifications: Every component, including the 127-tooth ring gear, is engineered and made to Original Equipment specifications. The ring gear chamfer matches OE.
- Dynamically balanced: The solid flywheel is balanced to help minimize vibration and support clutch performance.
- Always new: LuK flywheels are new units. LuK's engineering and quality materials are designed to contribute to longer service life for the flywheel and clutch system.
A flywheel bolts to the crankshaft, gives the clutch disc its friction surface, and carries the ring gear that the starter engages. This flywheel comes with dowel pins. Replacing the flywheel with a new one when you install a clutch set is a cost-effective alternative to resurfacing the original.
Specifications: friction surface OD 290 mm (11.417 in) and ID 193 mm (7.598 in); outside diameter 326.35 mm (12.848 in); ring gear mounting OD 294.3 mm (11.587 in); ring gear thickness 10.15 mm (0.400 in); flywheel thickness 36.45 mm (1.435 in); crank to friction surface 41.87 mm (1.648 in); pilot I.D. 25.2 mm (0.992 in); crankshaft bolt-hole PCD 73 mm (2.874 in); pressure plate bolt-hole PCD 304 mm (11.969 in); dowel hole diameter 6 mm (0.236 in); flange thickness 25 mm (0.984 in). Country of origin: Thailand.
Signs a flywheel may need replacing include clutch chatter or judder on engagement, vibration, a scored or heat-spotted friction surface, and damaged ring gear teeth that grind during starting. Diagnose the cause before replacing any parts. Consult the vehicle service information for the correct fasteners and whether they may be reused.
