A symptom of clutch slip is
A vehicle producing a very severe vibration
or jerk)‘ motion when taking off .
B transmission grinding trying to engage or
shift gears.
C a stiff clutch pedal .
D engine speeding up without an increase in
the vehicles road speed.
6.
During repairs, the value of clutch pedal frccplay when properly adjusted should be
A between 11.5cm and 13cm.
B about 20cm.
C half a centimeter.
D about 5cm.
2.
In the torque converter, the flow of oil is
redirected to the impeller by
A turbine.
B impeller.
C flywheel.
D stator.
7.
Two functions of the synchronizer in the
manual shift gearbox are to
A equalize lay and main shaft gears speed
thus preventing gears from grinding.
B prevent mating gears from grinding or
clashing and lock the output gear to the
input shaft.
C divide gear speeds and prevent clashing
gear teeth.
D increase gear speeds and facilitate
engagement.

In the simple epicyclic gear train shown in
figure 2 neutral condition is obtained by

Some common symptoms of a malfunctioning
synchromesh unit include
A clutch slip, gears grinding between change
and clutch dragging.
B clutch slipping and a quicker gear change.
C difficulty in engaging gears, gears
clashing during engagement and gears
jumping out of mesh after engagement.
D clutch spinning and gears jumping out of
mesh after engagement.

A locking together any two members while
the third is being carried around by the
teeth of the locked members.
B holding the annulus and the sun gear
rotated.
C holding any one member and the two
allowed to run freely.
D holding the planet carrier fixed while the
sun is rotated.

Semi centrifugal type clutches used in highspeed engines and racing cars
A don’t use clutch pedals.
B makes use of clutch springs to transmit
power at low engine speeds centrifugal
force transmit power at high engine speed.
C rely on centrifugal force to transmit
power.
D uses only clutch spring to transmit torque
at all engine speeds.

A Single plate clutch.
B Fluid coupling.
C Dog clutch.
D Centrifugal clutch.
Over drive is provided in transmission of a
vehicle to
A improve fuel consumption
B reach higher road speeds
C achieve better acceleration
D carry more load
i
The type of independent suspension system
which is simple in construction and allow more
deflection of the front wheel without effect on
the steering is
A strut type suspension.
B torsion bar suspension.
C coil spring suspension.
D conventional suspension.
17.
12. Gears jumping out of position in a manual
gearbox is caused by
A worn synchronizer
B bend gear fork
C low lubricant
D worn spline shaft
An advantage of a disc brake over an internally
expanded shoe brake is
A small effort gives larger braking torque.
B fades temperature are lower.
C great resistance to fade.
D greater self–servo action at high speed.
13. Differential lock comes into operation when the 18.
A vehicle is negotiating a bend.
B tyres are worn.
C tyres or road wheels are on a slippery
surface.
D driver wants the passengers to be
comfortable.
19. The type of spring which offers good load
carrying capacity and do not have noise in the
suspension system is
A multiple leaf spring.
B coil spring.
C mono leaf spring.
D fiber composite springs
