Chapter 31 The Clutch System questions and answers with
complete solution
What are the two most common pressure plate designs?
Select one:
a. Viscous and coil spring
b. Diaphragm and floating disc
c. Dual mass and diaphragm
d. Diaphragm and coil spring
d. Diaphragm and coil spring
While preparing a manual transmission/transaxle to be reinstalled, Tech A says the
input shaft splines should be lightly lubricated to prevent binding during assembly. Tech
B says the components should be assembled totally dry, as there is too much risk of
lubricant getting onto the disc faces. Who is correct?
Select one:
a. Tech A
b. Tech B
c. Both Techs A and B
d. Neither Tech A nor B
a. Tech A
Technician A says clutch slippage can best be diagnosed with the vehicle stopped,
parking brake applied, placing the transmission in 4th gear, and slowly releasing the
clutch pedal to see if it stalls the engine. Technician B says an excessively slipping
clutch can cause friction surface warpage or hot spots. Who is correct?
Select one:
a. Technician A
b. Technician B
c. Both Technician A and Technician B
d. Neither Technician A nor Technician B
c. Both Technician A and Technician B
If the clutch pedal is ________, the technician should perform some preliminary checks,
such as checking the level of fluid in the hydraulic clutch master cylinder, before test-
driving the vehicle.
Select one:
a. Worn
b. Rigid
c. Spongy
d. Resistant
c. Spongy
One advantage of using a multi-plate clutch is increased torque capacity. Another
advantage of this design is:
Select one:
a. no increase in spring pressure is needed.
b. no increase in diameter is needed.
, c. no increase in pedal effort will occur.
d. All of the above
d. All of the above
Increasing the spring force of the pressure plate that clamps the clutch disc to the
flywheel increases torque capacity but takes more foot pressure to operate the clutch
pedal.
Select one:
True
False
True
Technician A says a diaphragm-type pressure plate requires less pedal effort to operate
than a coil spring type. Technician B says a clutch with a coil spring type pressure plate
uses one large spring to create the clamping force. Who is correct?
Select one:
a. Technician A
b. Technician B
c. Both Technician A and Technician B
d. Neither Technician A nor Technician B
a. Technician A
Continuing to drive a vehicle with insufficient clutch pedal free play would likely result in:
Select one:
a. premature failure of the clutch assembly.
b. excessive wear on the pilot bushing.
c. clutch hydraulic cylinder failure.
d. excessive wear on the transmission input shaft.
a. premature failure of the clutch assembly.
The inner workings of the _________ helps absorb engine vibrations, thus minimizing
gear rattle and putting less strain on the drivetrain components.
Select one:
a. Flywheel ring gear
b. Single one-piece flywheel
c. Dual mass flywheel
d. Planetary gearing flywheel
c. Dual mass flywheel
The automotive technician should check that all hydraulic lines are not kinked or leaking
at their connection points.
Select one:
True
False
True
A vehicle has clutch pedal pulsation whenever the pedal is applied. Tech A says the
pulsation may be the result of clutch abuse and overheating. Tech B says the cause
may be lever misalignment in the pressure plate. Who is correct?
Select one:
a. Tech A
b. Tech B
