Repeatedly engage and disengage the clutch
Drive the vehicle turning on both full left hand and right hand locks
Drive the vehicle at a constant speed on a straight road
Change down through all the gears
A constant velocity joint is used;
In a fully floating axle
In a rigid axle
In a dead axle
In a front wheel drive shaft
In a four-speed constant mesh gearbox the gears on the output shaft are always;
Integral with the output shaft
Splined to the output shaft
Straight cut gear teeth
Free to rotate on the output shaft
The gears used in a constant mesh gearbox are called;
Helical gears
Epicyclic gears
Hypoid gears
Spur gears
A worn rear wheel bearing is likely to make;
No noise
Humming noise
Knocking exhaust
A knocking noise
Misaligned propshaft universal joints on a rear wheel car can cause:
The clutch to judder
The transmission to whine at very high speeds
The transmission to vibrate
The clutch to wear excessively
A “live” rear axle arrangement:
Adjusts to road conditions
Is only fitted at the front of a vehicle
Combines gearbox and final drive components
Combines the differential and final drive in a rigid casing
Difficulty in engaging gears is most commonly caused by:
A clutch judder
A tight clutch cable
A weak clutch spring
A worn gear linkage
To give smooth transmission, front wheel drive vehicles use:
Constant velocity joints
Unequal length driveshafts
Sliding joints in the driveshafts
Hollow diveshafts
Which of the following clutch components is connected to the gearbox input shaft?
The pressure plate springs
The clutch cover drive straps
The centre plate splines
The release bearing arms
In a hypoid final drive unit the:
Limited slip differential is in the pinion
Pinion is offset to the centre line of the crown wheel
Pinion is positioned on the centre line of the crown wheel
Worm and wheel design is used
A coil spring clutch is
Heavier and more suitable to high engine speeds than a diaphragm clutch
Lighter and more suitable to high engine than a diaphragm clutch
Heavier and less suitable to high speeds than a diaphragm clutch
Lighter and less suitable to high engine speeds than a diaphragm clutch
A clutch has an excessive amount of free play, this could:
Make it difficult to disengage the clutch
Cause the clutch to occasionally slip
Make the clutch wear excessively
Make the clutch heavy
In a manual gearbox the purpose of an interlock mechanism is to:
Lock the gear in place once it has been selected
Prevent the gears from crashing during gear changing
Connect the gearstick to the gearbox using a linkage
Prevent two gears being selected at the same time
Which type of bearing is normally used in a semi floating hub arrangement?
Brass bearing
Plain bearing
Needle roller bearing
Taper bearing
If air is present in a hydraulic clutch operating system, this will:
Produce clutch judder during engagement
Cause clutch to slip when pulling away
Make it difficult to disengage the clutch
Cause the fluid to overheat
Transmission “Knocking” noise can be caused by a:
A badly scored flywheel
A worn prop shaft universal joint
A badly worn clutch centre plate
A badly worn gearbox synchromesh hub
A detent ball and spring mechanism is often used to:
Synchronise the speeds of the gears
Lock the selector shafts in position
Prevent excessive gear shaft end float
Lock the final drive gear
To allow for changes in the prop-shaft length due to suspension movements:
A universal joint is fitted
A rubber gaiter is fitted
A cv joint is fitted
A sliding joint is fitted
Which of the following is a likely cause of clutch slip?
Very dry clutch plate
Worn clutch pedal bushes
Not enough clutch free play
Too much clutch free play
A damaged gearbox interlock mechanism could allow:
The transmission to completely lock up
The driver to select reverse when driving
The gear lever to fall out
The gears to come loose on the main shaft
The component which transmits the drive between the input shaft and the main shaft in a rear wheel drive gearbox.
Lay shaft
Gear linkage
Differential
Synchromesh hub
The force a diaphragm clutch exerts on a friction plate:
Is adjustable for the friction plate wear
Decreases with friction plate wear
Remains constant with friction plate wear
Increases with friction plate wear
Multi plate clutches are often used when the flywheel diameter is limited and:
The engine produces high torque
The spring force has to be increased
The engine produces high revs
The engine produces low torque
What is a typical final drive ratio?
8:1-10:1
3:1-4:1
14:1-15:1
17:1-18:1
