Product Details

LuK has extensive experience in hydraulic clutch release systems, and this master cylinder reflects that background in a service replacement format. The LMC165 is intended for vehicles using a hydraulic clutch actuation setup where the master cylinder is the source of clutch pedal pressure transfer. It cross-references Dorman - First Stop CM39820 and FEL-PRO 12665 for the same application. Use the LuK LMC165 when replacing a worn or leaking clutch master cylinder on manual transmission vehicles such as the Mazda 6, Ford Fusion, and Mercury Milan.

Common Repair Symptoms

• Soft or inconsistent clutch pedal feel
• Difficulty disengaging the clutch
• Hydraulic fluid leakage at the master cylinder
• Pedal travel changes after clutch system wear
• Loss of clutch release pressure in manual transmission operation

Installation Notes

Installation instructions are included. Because this unit is not pre-filled and not pre-bled, the hydraulic system must be filled and bled after installation. Verify the vehicle’s clutch hydraulic layout before service, and confirm fitment against the exact year, make, and model listed for your application. The part is supplied with a push rod and without a clutch slave cylinder.

Quality Assurance

LuK, part of Schaeffler, has long-standing expertise in complete clutch release systems and hydraulic clutch technology. The LMC165 is a new part built for service replacement in confirmed manual transmission applications.
