Luk LFW174 Clutch Flywheel

LuK LFW174 Clutch Flywheel Overview

The LuK LFW174 clutch flywheel is a direct-fit replacement for select Saturn manual transmission applications. Built to OE specifications, it provides the smooth, flat friction surface needed for consistent clutch engagement and reliable drivability.

Detailed Description

The LuK LFW174 is a clutch flywheel designed for Saturn manual transmission service where a true, flat mating surface is critical. During clutch replacement, the flywheel plays a central role in pedal feel, engagement quality, and overall clutch performance. This OE-spec replacement is a cost-effective option versus resurfacing when the existing flywheel is worn, heat-checked, or no longer within service limits.

This part cross-references Sachs NFW1900 for the same application. It is a strong match for Saturn SL1 and SL2, as well as Saturn SC1, SC2, SL, SW1, SW2, and SC fitments across the listed model years. The LuK LFW174 is built as a new component, not a remanufactured unit, and follows OE dimensions for proper installation and clutch alignment.

What It Helps Address

• Clutch chatter or uneven engagement caused by a worn flywheel surface
• Heat spots, scoring, or glazing on the existing flywheel
• Vibration during clutch take-up
• Poor clutch contact after a previous resurfacing limit has been reached
• Noise or drivability issues related to flywheel wear

Installation Notes and Tips

• Verify flywheel diameter, tooth count, and inner diameter before installation.
• Inspect the clutch disc, pressure plate, and release components during service.
• Confirm the crankshaft mounting surface is clean and free of damage.
• Use the correct torque procedure and service sequence for the vehicle.
• Check fitment carefully for 1991-2002 Saturn SL1 and SL2, 1993-2000 Saturn SC1 and SC2, 1991-2000 Saturn SL, 1993-2000 Saturn SW2, 1993-1999 Saturn SW1, and 1991-1992 Saturn SC.
