163 TRANSMISSION

Full name:

Q1. The gear change operation in a CVT transmission relies on a

• torque converter
• selectors and synchromesh hubs
• fixed pulleys and belt
• moving pulleys and belt

Q2. A CVT transmission would provide

• one forward and one reverse ratio.
• 6 individual ratios
• 5 individual ratios
• smooth unlimited ratios

Q3. After fitting taper roller bearings in a final drive unit they would need to be

• shrunk to fit
• preloaded
• preselected
• stretched to fit

Q4. One cause of a leaking final drive pinion oil seal is

• excessive differential side gear end float
• lack of pinion bearing preload
• worn synchromesh device.
• loose planet wheel spindle

Q5. A fault which causes only third gear to crunch, when being selected in a synchromesh gearbox, would be

• a worn thrust bearing
• a worn baulk ring
• lowfluid level in clutch master cylinder
• a chipped third gear tooth

Q6. One main component which would be identified within a Continuously VariableTransmission, would be a

• layshaft gear assembly
• steel belt
• synchromesh device
• turbine and impeller.

Q7. To operate a manual six forward speed conventional gearbox, it would require

• 6 synchromesh hubs
• 3 synchromesh hubs
• 12 synchromesh hubs
• 2 synchromesh hubs

Q8. One method used to enable selection of a sequential manual gearbox is

• pinion shaft and selector drum
• continuous chain and gears
• electric motor and rotating selector drum
• magnetic rollers and selector drums

Q9. A transmissions electronic speedometer uses a

• high voltage coil
• high voltage spark.
• pulse generator
• phased generator
