Clutch Base Plate 003002002130
Wear compensation for SACHS carbon clutch RCC 140
Consistent performance over the entire service life: the ZF Motorsport SACHS RCC 140 base plate 003002002130 establishes the correct installation height (stack height) of the carbon clutch pack. For the RCC 140 the base plate is supplied in a single build height and reliably brings the diaphragm-spring geometry back into the nominal range. Carbon-wear compensation is handled in fine steps via selection of the appropriate pressure ring. Working together, base plate and pressure ring set the carbon stack height precisely to target—keeping the 140 mm carbon racing clutch’s torque capacity stable across service intervals, with a crisp pedal feel and repeatable clamp load.
For precise service setups, pressure rings are available in fine thickness steps (e.g. 0.25 mm). The base plate itself is a wear item and should be inspected during overhaul (run-out, thickness, surface); replace as required—especially when a new pressure ring is installed for compensation.
Key benefits
Stable torque capacity
Longer carbon stack life
Fine adjustment via pressure rings
Highest manufacturing quality
Service-friendly
Technology
Base plate RCC 140
Function: the base plate establishes the baseline installation height and brings the diaphragm-spring fulcrum/clamp dimension into the nominal range. As the RCC 140 uses a single base-plate height, carbon-stack wear compensation is achieved by selecting the correct pressure ring to reset installation height and restore original kinematics.
Steps: base plate in fixed height; pressure rings in 0.25 mm increments for precise restoration of installation height.
Overhaul/service: the base plate can wear. Inspect at each overhaul (run-out, thickness, surface) and replace as required—especially when a new pressure ring is fitted.
Quality standard: manufactured to ZF Motorsport specification with tight run-out and thickness tolerances for repeatable clamp load.
Practice / installation notes
Measure stack height: determine carbon pack (friction and intermediate plates) per series spec; record actual stack.
Target/actual check: consult RCC 140 series specification; the difference defines the required pressure-ring step.
Selection: choose the pressure ring so installation height lies within nominal; avoid over-compensation.
Wear limit: if permissible total wear is exceeded, torque capacity drops rapidly (slip, heat build-up, excessive release travel). Replace the carbon pack—ring/base-plate changes alone are insufficient.
