What is the frequency at which the driveline's vibrations are the most damaging?
Resonance
What type of discs do not absorb engine torsional vibrations?
Rigid
, Which of the following could cause clutch hang-up?
misaligned intermediate plate drive pins

As clutch friction facings wear on a truck pull-type clutch, how is clutch pedal
free travel affected?
decreases
The harder the clutch is squeezed between the pressure plate and the flywheel,
the greater the ______the clutch can handle.
torque
A clutch that has too much free play can cause which of the following?
Gear clash
A driver reports that the free pedal in his cab is only half as much as it used to be.
What could be the problem.

A properly adjusted _________ clutch has a certain clearance between the tips of
the release fork and the wear pads on the release bearing.
pull-type
A properly adjusted push-type clutch will usually have a certain amount of
______________ between the clutch release levers and the release bearing.
free play
After bleeding the hydraulic clutch system, what type of specified fluid would you
fill the master cylinder with?
Brake
As the clutch wears, which of the following becomes thinner?
Friction disc
Clutch linkage must be adjusted to gain proper brake squeeze. ________the
linkage will lower the squeeze point.
Lengthening
In a clutch, which of the following supports the release fork?
Cross-shaft
Technician A says excessive clutch pedal free travel can result in a clutch that
does not fully disengage. Technician B says that too little free pedal travel can
result in a slipping clutch. Who is correct?
.Both A and B
Technician A says that coasting when a clutch is disengaged can cause engine
overspeed. Technician B says that coasting with a clutch disengaged can spin
the driven discs at speeds as high as 10,000 rpm due to the multiplication of
drivetrain ratios. Who is correct?
Technician B only
Technician A says that one of advantages of a clutch brake is its ability to bring a
vehicle to a halt at low speeds. Technician B says most current clutch brakes are
intended to smooth shifts from neutral to either first or reverse. Who is correct?
Technician B only
