practice test

clutch disc

particle composition depends on vehicle application & can be made of paper, ceramic, rope, wire, and/or asbestos

cover plate

holds all components in place within the pressure plate assembly & provides a backing surface, against which springs can push.

Pilot bushing

typically made of solid bronze to avoid input shaft damage

pilot bearing

needle bearing covered with steel outer shell

clutch release fork 

pushes on the clutch release bearing to operate the clutch

Standard Flywheel

uses a torsional clutch disc

dual mass flywheel

contains a dampener that reduces vibrations

friction surface

cools the clutch

primary flywheel 

faces the engine in a dual mass flywheel 

secondary flywheel

faces the transmission in a dual mass flywheel

Clutch hub

what holds the dampening coil spring in place?

Cover plate 

what provides backing for the coil springs to hold pressure on the clutch disc?

Stop pin

what limits the torsional movement of the dampener?r

rivets

What prevents the friction material from slipping off the metal backing?
