Sample questions

1. The oil in the transmission box is changed:

   • while the engine is running, the clutch engaged and with a neutral position of the gear lever
   • while the engine is running and with the clutch disengaged
   • while the engine is off

2. The function of the main transmission is:

   • only to reduce the torque transferred from the cardan drive to the driving wheels by changing its direction
   • only to change the direction of the torque transferred from the cardan drive to the driving wheels
   • to amplify the torque transferred from the cardan drive to the driving wheels by changing its direction

3. When the level of the fluid in the hydraulic cylinder tank of a hydraulically actuated clutch is reduced:

   • water is added
   • the same type of fluid is added
   • ethyl alcohol may be added
   • any kind of technical-purpose fluid may be added

4. When the clutch pedal is pressed:

   • the clutch is disengaged and the power train is uncoupled
   • the clutch is disengaged and the power train is coupled
   • the clutch is engaged

5. The type of oil in the casing of the steering axle and the period of oil change is determined by:

   • the driver, depending on weather conditions
   • the vehicle manufacturer
   • the driver, depending on road conditions

6. When the engine is running and the clutch is engaged, the transmission box is directly driven by:

   • the crank shaft of the internal combustion engine
   • the cardan drive
   • the clutch

7. Checking the level of fluid in the clutch tank is a compulsory operation:

   • for all clutch types
   • only for truck clutches
   • for hydraulically actuated clutches

8. The function of the transmission box is:

   • to change the transferred torque
   • only to couple the internal combustion engine to the transmission
   • to secure the turning of the front wheels

9. The transmission box is a component (unit) of:

   • the steering mechanisms of the vehicle
   • the power train (transmission) of the vehicle
   • the vehicle chassis
   • the steering system

10. The “sliding” of the clutch plates is an indication of:

    • large free play of the clutch pedal
    • small free play of the clutch pedal
    • normal free play of the clutch pedal
