Question

technician a says that waved springs between the clutch facings results in a smoother engagement of the clutch when starting from a stop. technician b says that the heavy torsional coil springs in the clutch disc clamp the clutch disc between the flywheel and the pressure plate. who is correct?
a. technician a
b. technician b
c. both technician a and technician b
d. neither technician a nor technician b

Explanation:

• For Technician A: Waved springs (also called wave washers or diaphragm springs in some contexts, but waved springs between clutch facings) do help in providing a smoother engagement by allowing a more gradual contact and pressure distribution when the clutch is engaged from a stop.
• For Technician B: The heavy torsional coil springs in the clutch disc are actually for damping torsional vibrations (like engine torque fluctuations) and not for clamping the clutch disc between the flywheel and pressure plate. The clamping force is provided by the pressure plate's springs (like diaphragm or coil springs in the pressure plate assembly), not the torsional springs in the clutch disc. So Technician B's statement is incorrect. Since only Technician A is correct, we analyze each statement.

Answer:

a. Technician A
