Chapter 36—Clutches
TRUE/FALSE
1. Clutch slippage occurs when the clutch disc is not gripped firmly between the flywheel and the
pressure plate.
ANS: T PTS: 1
2. Chatter is a shuddering felt in the vehicle when the pressure plate releases the
clutch disc.
ANS: F PTS: 1
3. Chatter is caused by liquid contaminants on the friction surfaces.
ANS: T PTS: 1
4. Clutch drag occurs if the clutch disc is not completely released when the
depressed. clutch pedal is fully
ANS: T PTS: 1
5. Until recently, the material that was molded or woven into facings of the clutch disk was
predominantly asbestos.
ANS: T PTS: 1
6. When compared to a diaphragm-type pressure plate, a coil spring pressure plate assembly has fewer
moving parts.
ANS: F PTS: 1
7. There is approximately 10 psì residual pressure in the hydraulic clutch lines when the clutch is in the
engaged position.
ANS: F PTS: 1
8. Shaft and lever clutch linkage are used on most modern passenger cars.
ANS: F PTS: 1
9. The fluid level in the hydraulic clutch reservoir should be approximately one-
fourth inch from the top.
ANS: T PTS: 1
10. Most hydraulic clutch release systems should be adjusted once a year.
, ANS: F PTS: 1
Some transaxles have a short, self-centering input shaft that does not require a
11. pilot bushing or bearing.
, ANS: T PTS: 1
12. Particles of cotton, brass, rope, and wire are added to prolong the life of the
clutch disc and provide
torsional strength.
ANS: T PTS: 1
13. Coil spring-type pressure plates require less pedal effort than diaphragm-type
pressure plates.
ANS: F PTS: 1
14. When the clutch is fully engaged, the release bearing is normally stationary.
ANS: T PTS: 1
15. The flywheel should not be resurfaced unless there are hot spots on its surface
or themade
clutch disk have rivetscontact
on thewith the flywheel surface.
ANS: F PTS: 1
