Product Details

LuK has extensive experience in hydraulic clutch release systems, and the LMC225 reflects that focus with a replacement design for the clutch hydraulic circuit. This clutch master cylinder is built for 1986-1991 Mazda RX-7 vehicles and is intended for drivers replacing a worn or leaking master cylinder in a manual transmission setup. The LMC225 is a direct-fit service part for Mazda RX-7 clutch hydraulic repair and is also referenced by cross numbers such as Dorman - First Stop CM112865 and Sachs SH5018 for the same application.

What It Helps Fix

  • Soft or inconsistent clutch pedal feel
  • External fluid leakage at the master cylinder
  • Difficulty disengaging the clutch
  • Loss of hydraulic pressure in the clutch system
  • Pedal travel issues caused by internal seal wear

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. The push rod is included, and the part installs without a clutch slave cylinder. Verify the vehicle is a 1986-1991 Mazda RX-7 before installation and inspect the hydraulic lines, fluid condition, and related clutch components during service.

Quality Assurance

LuK, part number LMC225, is backed by Schaeffler’s experience in complete clutch release systems and hydraulic clutch technology. This new replacement clutch master cylinder is built for service work where accurate hydraulic operation and consistent pedal response are required.
