SACHS RCS 140 Release Ring 003074000333
Clutch release ring for axial adjustment of the release bearing and racing clutch
SACHS RCS racing clutches from ZF-Motorsport are not designed for a specific vehicle and must be adapted to the available installation space of the respective vehicle. Release rings are used to correctly set the axial position of the release bearing or concentric slave cylinder relative to the diaphragm spring of the racing clutch.
The release rings are mounted on the diaphragm spring of the SACHS RCS 140 clutch. They enable the use of a release bearing or slave cylinder with a flat contact face and are especially relevant when a standard release bearing with a flat contact surface is used.

Benefits
Targeted axial adjustment of the release bearing or concentric slave cylinder
Suitable for SACHS RCS 140 racing clutches with 1 diaphragm spring
Enables the use of release bearings with a flat contact face
Important when using standard release bearings with a flat contact surface
Various nominal thicknesses for adaptation to clutch, flywheel and gearbox
Supports a defined bearing position and reproducible clutch actuation
Technology
Release ring & bearing position
Function: Release ring 003074000333 changes the axial contact position of the release bearing relative to the diaphragm spring. This allows the SACHS RCS 140 racing clutch to be adapted to the available installation space of the vehicle.
Application: The ring is mounted on the diaphragm spring of the clutch and forms a defined contact face for release bearings or concentric slave cylinders with a flat contact face.
Nominal thickness A: Dimension A describes the nominal thickness of the release ring. For this RCS 140 version, different heights from 5.0 mm to 15.0 mm are available.
Compatibility: The release rings are intended for SACHS RCS 140 clutch covers (housings) with 1 diaphragm spring and a diaphragm-spring contact diameter of Ø 49 mm.
Design: Before installation, the clutch, flywheel, gearbox, release bearing, actuation system and available installation space must be measured together.
Geometry & Dimensions
Nominal thickness A
The technical drawing shows the position of release ring 003074000333 on the diaphragm spring of the SACHS RCS clutch. The decisive factor is nominal thickness A, which sets the axial position of the contact face for clutch actuation.
A: nominal thickness of the release ring
Ø 49 mm: diaphragm-spring contact diameter of the compatible clutch covers
Contact face: flat contact surface for release bearing or concentric slave cylinder
The suitable nominal thickness is selected according to installation height, bearing position and release-system travel.

Note: Before installation, the clutch version, diaphragm spring, diaphragm-spring contact diameter, release bearing, concentric slave cylinder and installation height must be technically checked.
Installation Notes
Installation & design
Measurement: Before installation, the clutch, flywheel, gearbox, release bearing and actuation system must be measured together. Nominal thickness A must match the required axial position of the release bearing.
Contact face: The release ring is especially relevant when a release bearing or concentric slave cylinder with a flat contact face is used.
Working travel: After selecting the release ring, the remaining working travel of the release system must be checked. During operation, the release bearing must not be permanently preloaded or driven mechanically against its stop.
Compatibility: The listed release ring 003074000333 is intended for ZF SACHS RCS 140 clutch covers (housings) with 1 diaphragm spring and a Ø 49 mm diaphragm-spring contact diameter.
Installation: The release ring must be positioned cleanly on the diaphragm spring and fastened according to the technical specifications. Contact faces, bolts, clearance and runout must be checked before operation.
Inspection: In the event of wear, uneven actuation, noise or implausible pedal travel, the entire actuation system must be assessed together with the clutch, release ring and bearing.
