Question 1

A diaphragm clutch has a(n) ____________________ spring, also called a Belleville spring, that is used instead of release levers and coil springs.

Answer 1

diaphragm

Question 2

The ____________________ is the inner part of the disc. It includes the splines that slide over the input shaft.

Answer 2

clutch hub

Question 3

A clutch is found on vehicles with automatic transmissions.

Answer 3

False

Question 4

A ____ is used on a few vehicles to reduce noise and vibration and allow smoother gear shifting.

A)spread
B)housing
C)ball socket
D)dual mass flywheel

Question 5

Which of the following is LEAST-likely a component of the clutch?

A)Flywheel
B)Pressure plate
C)Shim
D)Clutch disc

Question 6

The part MOST-Likely attached to cover assembly at pivot points is:

A)release levers
B)shims
C)slip plates
D)clutch hub

Question 7

While having a discussion, Technician A says that standard release bearings remain in constant contact with the clutch cover. Technician B says that standard release bearings do not remain in constant contact with the clutch cover. Who is correct?

A)A only
B)B only
C)Both A and B
D)Neither A nor B

Question 8

All of the following statements are true EXCEPT:

A)Some newer hydraulic systems have the slave cylinder as part of the release bearing.
B)Hydraulic systems are popular on custom vehicles because adaptation of the clutch release mechanism is easy.
C)The output piston is located in the reaction or actuator cylinder, commonly called a slave cylinder.
D)The master cylinder input piston is located in the diaphragm spring.

Question 9

____________________ dampers are usually coil springs, although they are occasionally made of rubber. They are positioned between the disc plate and the clutch hub to absorb shock during engagement.

Question 10

____________________ control allows the clutch to be applied gradually.

Question 11

All of the following statements are true EXCEPT:

A)the release bearing is lubricated and then sealed at the factory.
B)self-centering release bearings are used on front-wheel-drive cars because they do not use a pilot bearing in the crankshaft.
C)curved release levers go against curved bearings, and flat release levers go against flat bearings.
D)some release bearings are flat on their face and others are curved.

Question 12

The ____ disengages the engine from the transmission, allowing it to continue running while the vehicle is at rest.

A)slave cylinder
B)clutch
C)radius plate
D)shim

Question 13

The pressure plate assembly is also called the ____________________ assembly.

Question 14

While having a discussion about clutch application, Technician A says that when you apply the pedal, you release the clutch. Technician B says that when you release the pedal, you apply the clutch. Who is correct?

A)A only
B)B only
C)Both A and B
D)Neither A nor B

Question 15

The part that MOST-Likely allows the pressure plate release mechanism to operate as the crankshaft rotates is:

A)shim
B)release bearing
C)slip plates
D)ball joint

Question 16

Which of the following statements is LEAST-Likely true?

A)Some release bearings found on older European cars use a round carbon ring that slowly wears away with each use.
B)An overcenter assist spring pulls the pedal toward the floor during the first half of travel and upward during the second half of travel.
C)The clutch fork fits between the release bearing and the clutch cable or linkage.
D)The release bearing hub has a provision to attach it to the clutch fork.

Question 17

A series of large rivets, called stop pins, prevent the hub from excessively compressing the springs.

Question 18

The engine side of the transmission input shaft is supported by a pilot bearing or sintered bronze bushing pressed into the end of the crankshaft.

Question 19

When compared to a diaphragm clutch, a coil spring clutch is better balanced.

Question 20

Facing material must be able to withstand the extreme heat that is generated as the clutch is slipped during engagement.

Question 21

What is a drawback to mechanical linkage systems?

Question 22

What are the advantages of coil springs over diaphragm springs?

Question 23

What are the disadvantages of a coil spring clutch?

Question 24

What is a drawback to clutch cables?

Question 25

What are some differences between a clutch master cylinder and a single brake master cylinder?
