Clutch Shim Kit 003074000434
Shim kit for SACHS carbon clutch RCC 2/140
Consistent performance across service intervals: the ZF Motorsport SACHS RCC 140 shim kit 003074000434 compensates wear of the carbon clutch pack and restores the original diaphragm-spring kinematics. The torque capacity of the 140 mm carbon racing clutch remains stable, with a crisp pedal feel and repeatable clamp load.
Shim kit contents: 7 pressure rings in fine 0.50 mm steps for precise service setups.
Maximum wear compensation: up to 4.30 mm (via the appropriate individual rings; see table).
Key benefits
Complete kit for maximum wear compensation
Longest carbon stack life
Stable torque capacity
Fine-step adjustment
Top manufacturing quality
Service-friendly
Technology
Shim kit RCC 140
Function: targeted compensation of carbon-stack wear by adjusting the fulcrum/clamp dimension at the clutch base plate. If the permissible wear limit is exceeded, torque capacity drops quickly: slip, heat build-up and excessive release travel may occur. The pressure rings in the shim kit precisely reset installation height and restore the original kinematics.
Steps: 0.50 mm increments for exact restoration of installation height.
Shim kit: 7 rings; wear compensation up to 4.30 mm (see table).
Material: high-strength tempered steel, burnished, for increased temperature and load-cycle resistance.
Quality standard: manufactured to ZF Motorsport specification; tight run-out and thickness tolerances.
Practice / installation notes
Measure stack height: determine the carbon pack (friction and intermediate plates) per series spec.
Target/actual check: use the SACHS RCC 140 wear table; the difference defines the required pressure-ring step.
Ring selection: choose the SACHS RCC 140 pressure ring so installation height lies in the target range; avoid over-compensation.
Observe the permissible wear limit. If exceeded, replace the carbon pack—ring change alone is not sufficient.
