This self-adjusting clutch includes a shipping plate which must not be removed prior to installation. If this plate is removed prematurely, the clutch will self-adjust and become unusable. Removing or tampering with this plate prior to installation will VOID THE WARRANTY! Installation requires a re-usable two piece tool, which must be purchased seperately. Part Number CT-1011

In recent years Self-Adjusting Clutches have become the standard equipment in applications with high engine torque or with increased requirements for wear reserve.

INSTALLATION NOTE: This self-adjusting clutch includes a shipping plate which must not be removed prior to installation. If this plate is removed prematurely, the clutch will self-adjust and become unusable. Removing or tampering with this plate prior to installation will VOID THE WARRANTY! Installation requires a re-usable two piece tool, which must be purchased separately.

Self Adjusting Clutch Assembly

The SAC uses a load sensor (sensor diaphragm spring) to activate its wear adjustment function by turning a ramped ring. This wear adjusting mechanism reduces the required actuation forces while increasing clutch life by around 1.5 times. In addition, actuation forces remain nearly unchanged throughout the clutches service life.

The SAC wear-adjustment system, which consists of the sensor diaphragm spring (load sensor) and a deep-drawn steel adjusting ring is characterized by its excellent functional accuracy. As clutch actuation comfort requires a harmonic operating load curve in addition to low actuation forces, the SAC was designed with the capacity to be tuned to each vehicle’s specific characteristic curve. One such feature is the compensation spring, which is able to generate the flatter characteristic curves that are frequently desired.

Features and Benefits:

  • Low release loads which remain constant throughout the entire service life
  • Therefore, excellent driving comfort throughout the entire service life
  • Increased reserve for wear and consequently longer service life thanks to automatic wear adjustment
  • Release bearing over-travel is prevented by the diaphragm spring end stop
  • Simplified release system design
  • Shorter pedal travel
  • New engineering concepts to reduce the clutch diameter (torque transfer)
  • Shorter release bearing travel throughout bearing life
