Clutch Shim Kit 003074000426
Shim kit for SACHS carbon clutch RCS 3/115
Consistent performance across service intervals: the ZF Motorsport SACHS RCS 3/115 shim kit 003074000426 compensates carbon clutch-pack wear and restores the diaphragm spring’s original operating point. The torque capacity of the 115 mm carbon racing clutch remains stable – with a clean pedal feel and repeatable clamp load.
Shim kit contents: 3 base plates + 3 pressure rings in fine graduated thicknesses for precise service setups.
Maximum wear compensation: up to 4.75 mm (via suitable combinations per wear table).
Key benefits
Complete kit for maximum wear compensation
Maximum service life of the carbon stack
Stable torque capacity over the entire duty cycle
Fine-step adjustment of installation height
Top manufacturing quality, tight thickness tolerances
Service-friendly, repeatable setups
Technology
Shim kit RCC 3/115
Function: targeted compensation of carbon-stack wear. Base plates primarily restore the static stack height, while pressure rings fine-tune the fulcrum/clamp point at the clutch base plate. Together they bring the diaphragm spring’s operating range back to nominal – for consistent clamp load, controlled release travel and minimized slip.
Steps: finely graduated, in 0.25 mm increments, to precisely restore installation height and resulting kinematics.
Shim concept: 3 base plates + 3 pressure rings per set; wear compensation up to 4.75 mm via suitable combinations (see wear-compensation table).
Material: high-strength tempered steel with surface treatment for temperature and load-cycle resistance.
Quality standard: manufactured to ZF Motorsport specification; tight run-out and thickness tolerances for repeatable results.
Practice / installation notes
Measure stack height: measure the carbon pack (friction and intermediate plates) as per series specification. Use RCS 3/115 reference dimensions.
Target/actual comparison: use the series-specific wear values; the difference defines the compensation required.
Ring/plate selection: choose a combination that keeps installation height in the target range; avoid over-compensation.
Observe wear limit: if exceeded, replace the RCS 3/115 carbon pack – changing rings/plates alone is not sufficient.
