- Technician A says that crankshaft counterweights offset the weight of the connecting rods and pistons. Technician B says that crankshaft counterweights are used to dampen crankshaft torsional vibrations. Who is correct? Technician A Technician B Both A and B d. Neither A nor Barrow_forwardTechnician A says that delayed shifting can be caused by worn planetary gearset members. Technician B says that delayed shifts or slippage may be caused by leaking hydraulic circuits or sticking spool valves in the valve body. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardWhile installing a timing belt: Technician A installs the belt, turns the crankshaft two full rotations, then applies tension to the belt.

- Which of the following is probably not the cause of a vibrating clutch? a. Excessive crankshaft end play b. Out-of-balance pressure plate assembly c. Excessive flywheel runout d. Loose flywheel boltsarrow_forwardWhile diagnosing a noise from a transmission: Technician A says that the noise is caused by something internal if it is most noticeable during a test drive. Technician B says that the noise is caused by the clutch if it disappears when the clutch is disengaged. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardWhile diagnosing the cause for an engine having good results from a compression test and cylinder leakage test but poor results from a cylinder power balance test: Technician A says that incorrect valve timing is the most likely cause. Technician B says that a severely worn cam lobe is a likely cause. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
- Technician A says that if a drive belt does not have the proper tension, it may produce squealing and chirping noises. Technician B says belt tension should be checked even if the engine has an automatic belt tensioner. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardA car jumps out of gear into neutral, particularly when decelerating or going down hills: Technician A checks the shift lever and external gearshift linkage first. Technician B says that the clutch pilot bearing could be the problem. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardTechnician A says that an in-line six-cylinder diesel engine is usually longer and heavier than a V8 engine of the same displacement. Technician B says that there are twice as many teeth on the crankshaft as there are on the camshaft sprocket. Who is correct? and why? Technician A Technician B Both A and B Neither A nor Barrow_forward
- When discussing shift problems,Technician A says that worn or broken engine and transaxle mounts can cause a transaxle to have shifting problems.Technician B says that poor shift boot alignment can cause a transaxle to jump out of gear?arrow_forwardWhile discussing ways to determine if a pilot bushing is faulty: Technician A says that if it operated quietly, it does not need to be replaced. Technician B says that a careful inspection of the transmissions input shaft can determine the condition of the pilot bushing. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardWhile diagnosing the cause of noise from a transfer case: Technician A says that a probable cause is incorrect tire size. Technician B says that the most probable cause is a faulty bearing or gear. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forward
