Clutch Shim Kit 003074000311
Shim kit for SACHS carbon clutch RCS 3/184
Consistent performance across service intervals: the ZF Motorsport SACHS RCS 3/184 shim kit 003074000311 compensates wear of the carbon clutch pack and restores the diaphragm spring’s original operating point. This keeps the torque capacity of the 184 mm carbon racing clutch stable – with a clean pedal feel and repeatable clamp load.
Shim kit contents: 4 base plates + 3 pressure rings in finely graduated thicknesses for precise service setups.
Maximum wear compensation: up to 5.75 mm (via suitable combinations per wear table).
Key benefits
Complete kit for maximum wear compensation
Maximum carbon stack service life
Stable torque capacity throughout the duty cycle
Fine-step adjustment of installation height
Top manufacturing quality, tight thickness tolerances
Service-friendly, repeatable setups
Technology
Shim kit RCS 3/184
Function: targeted compensation of carbon-stack wear. Base plates primarily restore static stack height, while pressure rings fine-tune the fulcrum/clamp point at the clutch base plate. Together they return the diaphragm spring’s working range to nominal – for consistent clamp load, controlled release travel and minimized slip.
Steps: finely graduated 0.25 mm increments to precisely restore installation height and resulting kinematics.
Shim concept: 4 base plates + 3 pressure rings per set; wear compensation up to 5.75 mm via suitable combinations (see wear-compensation table).
Material: high-strength tempered steel with surface finish for temperature and load-cycle resistance.
Quality standard: manufactured to ZF Motorsport specification; tight runout and thickness tolerances for repeatable results.
Practice / installation notes
Measure stack height: measure the carbon pack (friction and intermediate plates) per series specification; use RCS 3/184 reference dimensions.
Target/actual comparison: use the series wear values; the difference defines the required compensation.
Ring/plate selection: choose a combination that keeps installation height within the target range. Avoid over-compensation.
Observe wear limit: if exceeded, replace the RCS 3/184 carbon pack – changing rings/plates alone is not sufficient.
