Clutch Shim Kit 003074000373

Shim kit for SACHS carbon clutch RCC 3/140 and 4/140

Consistent performance across service intervals: the ZF Motorsport SACHS RCC 140 shim kit 003074000373 compensates carbon clutch-pack wear 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: 14 pressure rings in fine 0.25 mm steps for precise service setups.
Maximum wear compensation: up to 5.00 mm (via appropriate individual rings; see tables).

Key benefits

Complete kit for maximum wear compensation

Longest carbon stack service 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, excessive release travel). The pressure rings in the shim kit precisely reset installation height and restore the original kinematics.

Steps: 0.25 mm increments for exact restoration of installation height.

Kit: 14 rings; wear compensation up to 5.00 mm (see tables).

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 to keep installation height within the nominal range; avoid over-compensation.

Observe the permissible wear limit. If exceeded, replace the carbon pack—ring change alone is not sufficient.
