AUT 141-Chapter 37

5. Technician A says that an oil-soaked clutch disc can cause clutch chatter. Technician B says that clutch chatter can be caused by loose bell housing bolts. Who is correct?

B. Technician B only

9. Technician A says that if the hydraulic clutch reservoir is overfilled, the clutch may prematurely wear. Technician B says that if the fluid level is too low, the clutch may not disengage. Who is correct?

C. Both Technician A nor B

1. Technician A says that clutch slippage is most noticeable in higher gears. Technician B says that clutch slippage is not noticeable in lower gears. Who is correct?

D. Neither Technician A nor B

8. The pressure plate moves away from the flywheel when the clutch pedal is

Disengaged

Diaphragm

a flexible, impermeable membrane on which pressure acts to produce mechanical movement

14. The surface of the pressure plate contacts the

clutch disc

Free travel

the distance a clutch pedal moves before it begins to take up slack in the clutch linkage

Clutch disc

the part of a clutch that receives the driving motion from the flywheel and pressure plate assembly and transmits that motion to the transmission input shaft

Bleeding

the process of removing air from a closed hydraulic system

6. The clutch, or friction, disc is connected to the

transmission input shaft

10. Technician A says that all manual transmission vehicles have at least one pilot bearing or bushing for the input shaft. Technician B says that the pressure plate always rotates with the input shaft when the engine is running. Who is correct?

A. Technician A only

7. Technician A says that incorrect clutch adjustment can cause premature clutch disc wear. Technician B says that incorrect clutch adjustment can cause premature clutch release bearing wear. Who is correct?

B. Technician B only

4. Name three types of clutch linkages.

Shaft and lever linkage, cable linkage, Hydraulic-operated clutch linkage

5. What is used to measure clutch pedal play?

Tape measure input shaft

Chatter

a shaking or shuddering that is felt when the clutch or other device is engaged

13. Before making a clutch adjustment, it is necessary to

check the hydraulic fluid level

12. Insufficient clutch pedal clearance results in

premature release bearing failure

3. While discussing the different types of pressure plates: Technician A says that coil spring types are commonly used because they have strong springs. Technician B says that Belleville-type pressure plates are not commonly used because they require excessive space in the bell housing. Who is correct?

A. Technician A only

3. What is another name for the diaphragm spring?

Belleville Spring

4. While discussing the purpose of a clutch pressure plate: Technician A says that the pressure plate assembly squeezes the clutch disc onto the flywheel. Technician B says that the pressure plate moves away from the clutch disc so that the disc can stop rotating. Who is correct?

C. Both Technician A nor B

6. While discussing different abnormal clutch noises: Technician A says that pilot bushing noises are most noticeable in cold weather and usually occur when the pedal is being depressed and the transmission is in neutral. Technician B says that release bearing noise is most noticeable when the transmission is in neutral and occurs when the clutch pedal is depressed and stops when the pedal is fully released. Who is correct?

C. Both Technician A nor B

9. Which of the following is probably not the cause of a vibrating clutch?

Excessive crankshaft end play

1. Name two types of friction facings.

Molded and Women

2. True or False? If the fluid reservoir for a hydraulic clutch is low, the entire system should be checked for fluid leaks.

True

Clutch fork

a forked lever that moves the clutch release bearing and hub back and forth

Pilot bushing

a plain bearing fitted in the end of a crankshaft. The primary purpose is to support the input shaft of the transmission

Clutch release bearing

a sealed, prelubricated ball bearing that moves the pressure plate release levers or diaphragm spring through the engagement and disengagement process

7. Torsional coil springs in the clutch disc

are the mechanical force holding the pressure plate against the driven disc and flywheel

11. When the clutch is disengaged, the power flow stops at the

pressure plate and flywheel

2. While discussing ways to determine if a pilot bushing is faulty: Technician A says that if it operated quietly, it does not need to be replaced. Technician B says that a careful inspection of the transmission's input shaft can determine the condition of the pilot bushing. Who is correct?

B. Technician B only

8. While discussing the cause of a pulsating clutch pedal: Technician A says that this can be caused by low fluid level in the hydraulic system. Technician B says that this can be caused by a warped flywheel. Who is correct?

D. Neither Technician A nor B

Bell housing

a term often used for clutch housing

15. Which of the following would not cause clutch binding?

an oil-soaked clutch disc

Friction disc

in the clutch a flat disc, faced on both sides with friction material and splined to the clutch shaft. It is positioned between the clutch pressure plate and the engine flywheel. Also called the clutch disc or driven disc

Throwout bearing

in the clutch, the bearing that can be moved inward to the release levers and clutch-pedal action to cause declutching, which disengages the engine crankshaft from the transmission. A common name for a clutch release bearing.

10. When the clutch pedal is released on a hydraulic clutch linkage, the

master cylinder piston is released by hydraulic pressure
