LV12 Transmission

The purpose of the sliding joint on a propeller shaft is to allow for: 

• Any torque fluctuations that occur in the transmission 

• The drive to be transmitted through a variable angle 

• Changes in the propeller shaft length due to movement 

• The drive to be transmitted at constant velocity 

What type of gears are used in a sliding mesh gearbox? 

• Helical gears 

• Spur gears 

• Epicyclic gears 

• Hypoid gears 

Which of the following faults may produce clutch slip? 

• Lack of free play 

• Missing pedal rubbers 

• Too much free play 

• Lack of clutch fluid 

Multi-plate clutches are used when there is not much space and? 

• The friction force has to be increased 

• The friction force has to be decreased 

• The rate of wear needs to be reduced 

• A high torque has to be transmitted 

Which of the following is not a legal requirement when road testing a vehicle? 

• A current road fund license 

• Driver wearing a seat belt 

• Trade plates front and rear 

• A valid drivers license 

A detent ball and spring mechanism is often used: 

• To lock the selector shafts into position 

• To synchronise the speeds of the gears 

• In a constant velocity joint 

• To prevent excessive gear shaft end float

A fully floating hub arrangement is often used: 

• Four wheel drive cars 

• CVT transmission systems 

• Light commercial vehicles 

• Front wheel drive cars 

A FWD vehicle produces a knocking noise while cornering, what is the most likely cause? 

• A worn mainshaft bearing 

• A worn layshaft bearing 

• A worn differential bearing 

• A CV joint 

Air present in the hydraulic clutch mechanism will: 

• Cause the fluid to overheat 

• Produce clutch judder 

• Make it difficult to disengage the clutch 

• Cause the clutch to slip 

Insufficient clutch free play may cause: 

• The clutch to slip 

• Difficulty engaging gears 

• The clutch to drag 

• The clutch to judder
