A vehicle with a manual transmission will not disengage the clutch. ONE possible cause is a:
worn clutch pressure plate
contaminated clutch linings
broken friction plate torsional springs
friction plate sticking on input shaft splines
When engaging gear there is noticeable clutch judder. ONE possible cause is:
badly worn engine mountings
clutch cable worn
centre plate sticking on input shaft splines
broken clutch diaphragm spring
A typical gear ratio for 4th gear, in a five-speed gearbox is:
0.56:1
1.00:1
1.43:1
2.07:1
In a vehicle fitted with a manual transmission it 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
ONE possible cause of a manual transmission jumping out of gear is:
worn synchromesh baulk ring
worn selector forks
incorrect transmission fluid
weak interlock mechanism
What is the purpose of the grooves on the conical surface of a synchromesh baulk ring?
To allow a smaller contact area and thereby reduce friction between surfaces
To allow for better lubrication of the friction faces to prevent overheating
To provide a rapid breakdown of the oil film and allow the cone faces to lock
To prevent the engagement of more than one gear at a time
A vehicle is fitted with an overdrive gear arrangement. At cruising speeds this will mean:
torque output is increased, speed output is increased
torque output is reduced, speed output is reduced
torque output is reduced, speed output is increased
torque output is increased, speed output is reduced
