Exam 17: Torque Converters

What is another term used to describe the impeller used on a torque converter?

Which of the following components can be used to transfer engine crankshaft torque to the torque converter assembly?

At what pressure should shop air be regulated to test a weld-sealed torque converter?

Which of the following does most to determine the power output of a torque converter?

Where is a flex plate located?

Technician A says that when it is necessary to rebuild a torque converter stator assembly,it should be removed first.Technician B says that cracked stator vanes can be TIG welded.Who is correct?

Technician A says that during the coupling phase,the impeller and turbine should be turning within 10% of the same speed.Technician B says that the only time that the impeller and turbine turn at exactly the same speed is when the lock-up clutch is engaged.Who is correct?

What should be used to check endplay when inspecting a torque converter assembly?

When is vortex flow at its maximum during torque converter operation?

Technician A says that when a torque converter flex plate is used,a flywheel is never required.Technician B says that when a flex plate is used,the starter motor pinion engages with teeth on the converter housing.Who is correct?

What type of stator tends to be found in heavy-duty truck torque converters?

Which of the following is a key difference between a torque converter and other types of fluid couplings?

When will torque multiplication be the greatest?

Technician A says that a torque converter stator has a direct mechanical connection to the impeller.Technician B says that a torque converter stator has a direct mechanical connection with the turbine.Who is correct?

Technician A says that all heavy-duty trucks with automatic transmissions use centrifugal lock-up converters.Technician B says that a centrifugal lock-up clutch consists of a piston,clutch plate,and back plate.Who is correct?

Technician A says that a torque converter is a type of fluid coupling.Technician B says that because a torque converter makes no direct mechanical connection between the engine and transmission,some loss of torque output results when the unit is not in lock-up mode.Who is correct?

Which of the following components is locked to the front cover of a torque converter during the lock-up phase and not otherwise?

What usually connects a torque converter turbine to the transmission input shaft?

Technician A says that vortex flow is at its maximum at full stall.Technician B says that vortex flow is at a minimum during coupling phase.Who is correct?

When the impeller and turbine speeds are turning within 10% of each other,this is known as:
