When a clutch is fully engaged, which of the following describes what happens?

When a clutch is fully engaged, which of the following describes what happens?

• A. The flywheel disengages from the pressure plate
• B. A force is placed against the shifter sleeve through a bearing. The shifter squeezes a set of friction discs together
• C. The release bearing pushes the discs apart
• D. The hydraulic pump increases fluid flow to the clutch

Answer: (B)

When the clutch is fully engaged, the pressure plate clamps the clutch disc firmly against the flywheel, so engine torque is transmitted to the transmission. The release bearing interacts with the diaphragm/sleeve mechanism to apply that clamping force: as the bearing acts through the linkage, it moves the pressure plate to squeeze the friction discs together. This clamping creates the grip between the flywheel and the clutch discs, enabling power transfer from the engine to the transmission. The other scenarios describe disengagement (discs pulled apart) or hydraulic actions that aren’t what happens when the clutch is fully engaged.
