A clutch driven plate is splined to the gearbox:
layshaft
transfer shaft
output shaft
input shaft
A clutch is necessary to move a vehicle from a stand still because the engine develops:
low power at low speeds
low power at high speeds
high power at high speeds
high power at low speeds
The purpose of a simple ball and spring acting on a selector shaft is
to prevent accidental selection of reverse
to prevent two gears being selected at the same time
to hold the selected gear in mesh
none of the answers shown
The purpose of a simple idler gear, meshed between a layshaft and a mainshaft gear, is to:
change the speed of the layshaft gear
turn the mainshaft in the same direction as the layshaft
alter the gear ratio between the two gears
enable smaller mainshaft and layshaft gears to be used
A single plate clutch has one or more springs mounted between the:
cover and pressure plate
driven plate and the pressure plate
flywheel and the driven plate
flywheel and the cover
A single plate clutch:
normally has friction faces riveted to the pressure plate
has a driven plate which has one driving surface
has a driven plate which has two driving surfaces
has main thrust springs between the driven plate and cover
Drive for the speedometer is usually taken from the gearbox
input shaft
differential
countershaft
output shaft
In a final drive assembly, it is usual for the:
crown wheel to drive the pinion
pinion to rotate slower than the crown wheel
pinion to drive the crown wheel
crown wheel to be driven by the propshaft
In relation to hydraulic clutch release mechanisms, which of the following is true?
it has a master and slave cylinder
slave cylinder forces fluid in a pipe to the master cylinder
the clutch pedal is connected to the slave cylinder
the movement ratio is only set by the lever ratios
It is necessary to fit a constant velocity joint in the drive shaft of a vehicle
when a split propshaft and a centre bearing are used
with fully floating axle arrangement
when the driven wheels are also steered
with independent rear suspension
A multi-plate clutch may have
two friction plates and two intermediate plates
three friction plates and three pressure plates
three friction plates and two pressure plates
two friction plates and one intermediate plate
On a four-wheel drive vehicle, the transfer box is normally positioned:
between the engine and gearbox
on the front axle
At the rear of the gearbox
in the rear axle casing
One disadvantage of a cable clutch release mechanism is:
a release bearing clearance is not necessary
control may be affected by engine movement
it requires a slave cylinder
it requires regular topping up
One function of a vehicle clutch is to:
limit engine torque
provide a means of stopping the engine
quick acceleration from rest
disengaging the engine from the transmission
One function of the gearbox in a motor vehicle is to
allow the clutch to disengage
vary engine speed and torque
multiply the engine torque
provide a means of emergency braking
One purpose of a propeller shaft assembly is to?
turns the drive through 90 degrees
drive the road wheels
transmit a rotational drive through a varying angle
link the front and rear of the vehicle together
The clutch spigot bearing is positioned in the:
friction plate
end of the crankshaft/flywheel
clutch cover
release mechanism
The effect upon the gearbox output shaft when 1st gear is engaged is:
torque and speed are increased
torque and speed are decreased
torque is increased and the speed is decreased
torque is decreased and the speed is increased
The fourth gear ratio of most rear wheel drive light goods vehicles is
1:1
3:1
2:1
4:1
The most suitable axle shaft arrangement for a heavy commercial vehicle is
Three-quarter floating
Semi-floating
Quarter floating
Fully floating
Which component causes the inlet valve(s) to open?
Valve springs
Crankshaft
Timing chain
Camshaft
What simple function of a multimeter is used to check for a break in an individual wire (the wire is not part of a circuit)?
Continuity tester (noise indicates continuity)
Ammeter
AC volts
Voltmeter
Why are the main wires on a vehicle starter motor very large?
To create a large resistance
Because they have to allow a very large current flow
Because the voltage is very high
To reduce the current flow
What feature determines the stroke of an engine?
Select one:
Height of the piston
The length of the crankcase cylinder bore
The length of the crankshaft throw
Length of the connecting rod
A battery must be in a well-ventilated place when being charged because:
Select one:
explosive gases are being given off
toxic gases are given off
a lower charge voltage is required
it prevents the plates from buckling
Four post and single post are types of:
Select one:
bearing puller
vehicle lift
transmission jack
torque wrench
What feature determines the stroke of an engine?
Height of the piston
The length of the crankcase cylinder bore
The length of the crankshaft throw
The bore diameter X 2
Air is present in a hydraulic clutch operating system. This will:
produce clutch judder during engagement
cause clutch to slip when pulling away
cause the hydraulic fluid to overheat
cause the clutch to drag
A clutch is necessary when moving a vehicle from a stationary position because the internal combustion engine develops:
low power at low speeds
low power at high speeds
high power at low speeds
high power at high speeds
Why are the main wires on a vehicle starter motor very large?
To reduce the current flow
To create a large resistance
The main wires on a starter circuit are very small
Because they have to allow a very large current flow
