Clutch Carbon Pack 003074000317
Replacement friction pack for SACHS carbon racing clutch RCC 4/140
The carbon pack (4 friction discs + intermediate plates) restores the nominal stack height and the correct kinematics of the diaphragm spring. On RCC 140 the base plate is designed in a single build height; wear compensation is achieved by selecting the appropriate pressure ring. This keeps torque capacity, pedal feel and clamp load stable over the service interval.
Key benefits
Stable torque capacity at target stack
F1-grade carbon quality
Repeatable clamp load, clean pedal feel
Low mass/inertia, high thermal robustness
Top manufacturing quality, ultra-tight tolerances
Technology
Carbon pack RCC 140
Replace a worn carbon friction pack on RCC 4/140 clutches when the wear limit is reached or wear is uneven. After installation, set the exact stack height using the correct pressure ring; incorrect (too early/too thick) ring steps will cause malfunction.
Practice / installation notes
Measure stack height: determine the carbon pack (friction and intermediate plates); measuring points as per RCC 140 series specification.
Ring selection: when replacing the carbon pack, use a new reference pressure ring to restore the intended wear-in/stack geometry.
Base plate inspection: although the build height is fixed, the base plate also wears. At each overhaul check run-out/surface/thickness and replace together with the new pressure ring if required.
Functional check: after assembly, verify release travel/clearance; misadjustment leads to slip and heat.
