LV13 Revision Test 2

Which component, when engaged, allows maximum tractive force?

• Transfer box
• Differential lock
• Differential

ONE advantage of using a CVT transmission is:

• It uses epicyclic gearing making it very compact
• To increase the complexity
• 4, 5, or 6 possible gear ratios
• infinite number of possible gear ratios

What is the purpose of the grooves on the conical surface of a synchromesh baulk ring?

• Smaller contact area to reduce friction between surfaces
• Better lubrication of the friction faces prevent overheating
• provide rapid breakdown of the oil allowing synchronisation
• To prevent the engagement of more than one gear at a time

Which one of the following can be used as a third differential on a 4WD system.

• Viscous coupling
• Synchroniser hub
• Transfer box
• Hookes joint

A worn syncromesh baulk ring can cause

• The gears to crash when being engaged
• Excessive vibration on overrun
• Difficulty when disengaging gears
• Noisy reverse

The springs in the centre of the clutch disc help to

• Engage the clutch
• Slow down the pressure plate
• Provide a smooth take up of drive
• Make the engine smoother

When the clutch is engaged, is power transmitted from the engine to the manual transmission?

• Not always
• Yes
• No
• Maybe

Planetary gears are held in place by a

• Sun gear
• Ring gear
• Planet carrier
• Turbine

A typical gear ratio for 4^th gear, in a five speed gearbox is:

• 0.56: 1
• 1.00: 1
• 1.43: 1
• 2.07: 1

A vehicle with manual transmission has a tendency to jump out of gear. ONE possible cause is:

• Broken selector detent spring
• Low transmission oil level
• Worn synchromesh baulk ring
• Worn clutch friction plate
