AN217A564AC Dual Function Hydraulic Clutch Release Bearing Assembly

CRB-025-1

Hydraulic fluid pressure travels from the clutch master cylinder into this compact unit located inside the transmission housing. The pressure moves an internal piston that drives a release bearing forward against the clutch pressure plate diaphragm. This single action disengages the clutch so the driver can change gears.

Housing material is typically durable plastic or composite with a metal bearing surface designed for repeated clutch cycles. The AN217A564AC Dual Function Hydraulic Clutch Release Bearing Assembly is built as a direct replacement that restores the original hydraulic release function when installed correctly and the system is properly bled.

Core Functions
Main role of the AN217A564AC Dual Function Hydraulic Clutch Release Bearing Assembly is to turn hydraulic pressure into the mechanical movement that releases the clutch. Pressing the pedal sends fluid into the unit, extending the piston and bearing. This separates the clutch disc from the flywheel and pressure plate.

Releasing the pedal allows the unit to retract under spring force so the clutch re-engages smoothly. Even pressure distribution around the diaphragm helps prevent uneven wear. The dual-function design reduces the number of separate components in the release system and simplifies the hydraulic circuit inside the bell housing.

Purchase Motivation
Distributors and workshop groups choose this assembly because it covers a group of high-volume older models with one reliable part number. Keeping the AN217A564AC Dual Function Hydraulic Clutch Release Bearing Assembly in stock cuts the need to manage multiple similar codes and improves order fulfilment speed.

Repair shops benefit from shorter installation time once the gearbox is removed. The unit bolts into the original position and connects to the existing hydraulic line. Correct dimensional match and hydraulic interface reduce the chance of incorrect fitment and subsequent returns. Fleet operators maintaining mixed older vehicles gain faster turnaround when a clutch release fault appears.
