c. The clutch friction disc is stationary
A driver complains that his clutch drags when disengaged. Which of the following could cause this condition?
a. Glazed friction faces b. Loose flywheel bolts c. Clutch misalignment d. Warped pressure plate
d. Warped pressure plate
What is the function of a pilot shaft when installing a new clutch?
a. Align the transmission with the flywheel housing b. Ensure concentricity of the crankshaft with the bell housing c. Align the friction disc splines with the pilot bearing d. Ensure concentricity of the pressure plate with the flywheel housing
c. Align the friction disc splines with the pilot bearing
Extreme wear is observed on a transmission input shaft sleeve. Which of the following should be done to correct the problem?
a. Replace the transmission b. Use a repair sleeve and accommodating release bearing c. Repair wear marks and weld and refinish with crocus cloth d. Install a new release bearing only
b. Use a repair sleeve and accommodating release bearing
Which of the following would be the most likely cause of poor clutch release?
a. Worn clutch fork b. Noisy release bearing c. Air in the slave cylinder d. Worn friction disc
c. Air in the slave cylinder
Which of the following is the most common cause of gear clash when is occurs in gear ratios?
a. Defective synchronizer b. Dragging clutch c. Slipping clutch d. Damaged countershaft gear
b. Dragging clutch
After pilot bearing installation, what should it be lubricated with?
a. Plenty of wheel bearing grease b. A small amount of lithium grease c. A small amount of high temperature grease d. Dielectric compound
c. A small amount of high temperature grease
Which of the following is most likely caused by low lubricant levels in a manual transmission or transaxle?
a. Gear clashing b. Hard shifting c. Gear seizure or lock up d. Jumping out of gear
c. Gear seizure or lock up
When a transaxle is in neutral with engine running, a growling noise is heard. If the vehicle is in motion and the clutch is engaged, where is the problem most likely to be?
a. Transaxle input shaft bearings b. Intermediate shaft bearings c. First / Second synchronizer assembly d. Pinion and ring gear mesh
a. Transaxle input shaft bearings
A rear wheel drive transmission has a bearing rumble in all gears except in direct drive. The most likely bearing to be defective is:
a. Input shaft ball bearing b. Release bearing c. Pilot bearing d. Both B and C
a. Input shaft ball bearing
A noise is present when the engine is at idle, in neutral, and the clutch is engaged. The most probable cause is:
a. Input shaft ball bearing b. Output shaft bearing c. Pilot bearing d. Output shaft ball bearing
a. Input shaft ball bearing
A noise is only present when your foot is resting on the clutch pedal. The most probable cause is:
a. Input shaft ball bearing b. Pilot bearing c. Release bearing d. Counter shaft needle rollers
c. Release bearing
A noise is heard at engine speed with the clutch disengaged. What is the most likely cause?
a. Input shaft ball bearing b. Pilot bearing c. Release bearing d. Countershaft needle rollers
b. Pilot bearing
The transmission grinds into reverse after the clutch pedal is depressed, the probable cause is:
a. Reverse gear synchronizer is worn b. Reverse idler gear is worn c. Incorrect clutch free-play adjustment d. Reverse shaft brake is worn out
c. Incorrect clutch free-play adjustment
Transmission “pops out” of second gear only when decelerating. The most likely cause is:
a. 2nd speed gear b. 1-2 synchronizer sleeve c. 2nd speed synchronizer ring d. Both A and B
d. Both A and B?
While attempting to down shift into second gear, the attempted shift fails and a “grinding” noise is heard. The most likely cause is:
a. Clutch disengagement problems b. 1-2 synchronizer hub c. 2nd speed synchronizer ring d. All of the above
d. All of the above
