LuK 510016010 Clutch Slave Cylinder Replaces 1480083,1674914,3C117A564AA,4411103Maximum operating efficiency with minimal space requirements LuK manufactures hydraulic slave cylinders for semi-hydraulic clutch actuation systems. In semi-hydraulic systems the slave cylinder is usually located outside the transmission housing. It serves as an actuation device for the release shaft and fork. In this case, the slave cylinder is comprised of the housing, piston with sealing, a pre-charged spring and a bleed screw. The housing is often made of plastic and the cylinder is protected from dirt by a rubber boot. The pre-charged spring applies constant preload pressure to the release bearing, allowing it to rotate with the clutch even if the release system is not under load, preventing unwanted noise from the bearings and diaphragm spring fingers. The bleed screw simplifies flushing or filling the system during maintenance. Benefits: Weight optimized Long service life Simple construction - few moving parts Maximum operating efficiency with minimal space requirements
