Definitions:

Friction Discs

Components within a mechanical clutch that provide the necessary friction to transfer torque from the driving to the driven shaft, often made of materials that improve grip and durability.

Torsional Shock

A sudden and extreme twist or strain on a mechanical component due to rapid torque variation.

Clutch Shaft

A component in a vehicle's transmission system that connects the clutch to the gearbox, transmitting power from the engine to the transmission.

Pilot Bearings

Bearings that guide and support the end of the transmission input shaft within the crankshaft.
