Detailed Product Overview

Installation Notes and Tips

Before installation, verify the vehicle application and inspect the hydraulic line, pedal linkage, and slave cylinder condition. Because this unit is not pre-filled or pre-bled, the hydraulic system will need to be filled and bled after installation. The push rod is included, and the clutch slave cylinder is not included. On certain Ford F-150, F-250, and F-350 applications, a driveshaft center support bearing plate replacement with Ford part #F4TZ-4831A is noted in the fitment data; refer to LB150 for those applications.

Quality Assurance

LuK is part of Schaeffler’s clutch system expertise, with a long history in hydraulic clutch release technology. This new LMC170 clutch master cylinder is built for replacement service in manual transmission applications where OE-style fit and hydraulic function matter.
