6. Distinguishing Clutch Pressure Plate from Clutch Plate & Related Terms
The clutch and clutch plate assembly includes two main elements:
- Clutch Pressure Plate: Exerts force and transmits power via friction. Main failure: 'bad clutch pressure plate' (slip, harsh engagement, noise).
- Clutch Plate (Disc): The friction disc; mates with the flywheel and pressure plate, often with wear predictive indicators.
Governmental ISO/TS 16949 and SAE automotive standards increasingly specify test data for the full clutch assembly for quality and warranty compliance.
