Detailed Description

The LuK LMC489 is a hydraulic clutch master cylinder designed for Saturn manual transmission service where the original master cylinder has worn, leaked, or lost hydraulic pressure. This part number LMC489 is a direct-fit style replacement for the listed Saturn SC1, SC2, SL, SL1, SL2, and SW2 applications, making it a practical choice for restoring clutch pedal operation and hydraulic release performance.

LuK has extensive experience in clutch release systems, including the transition from mechanical to hydraulic designs. That background is reflected in this replacement master cylinder, which is supplied as a new component with installation instructions and a push rod. This part cross-references Dorman - First Stop CM640005 and Dayco 72489 for the same application.

What It Helps Fix

• Soft or sinking clutch pedal
• External hydraulic fluid leakage at the master cylinder
• Difficulty disengaging the clutch
• Inconsistent clutch pedal engagement point
• Loss of hydraulic pressure in the clutch release system

Installation Notes and Tips

Before installation, verify the vehicle application against the listed fitment for your Saturn SC1, SC2, SL, SL1, SL2, or SW2. Because this unit is not pre-filled or pre-bled, the hydraulic system must be filled and bled after installation to remove air from the circuit. Inspect the clutch hydraulic line, pedal connection, and slave cylinder condition during service to help avoid repeat repairs.

LuK is part of Schaeffler’s clutch and drivetrain engineering heritage, with long-standing expertise in hydraulic clutch release systems. The LMC489 is a new replacement part built for the specified Saturn manual transmission applications and supplied with installation instructions for service support.
