Transmissions (23 cards)
Tech A: says the flywheel and pressure plate assembly both rotate at engine crankshaft speed when the engine is running. Tech B: says when the engine is running and the transmission is in neutral the transmission input shaft May either be rotating or at rest. Who is right?
C: both
when the clutch engages. Springs Force clamps and the friction disc between the flywheel and the ________?
D
: pressure plate
tech A says most engine flywheels are lightweight to avoid causing inertia. Tech B says most engine flywheels are made of hardened Forge steel to absorb the heat of clutch operation. Who is right?
