Unit 7 Test Chapter 17 Torque Converters
At what pressure should shop air be regulated to test a weld-sealed torque converter
75 psi
In torque converter operation, when does the stator start to freewheel
At the beginning of coupling phase
When the impeller and turbine speeds are turning within 10% of each other, this is known as
Coupling phase
A flex plate can also be known as a flex
Disc
Which of the following does most to determine the power output of a torque converter
Engine rpm
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
Neither Technician A nor B
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
Neither Technician A nor B
What is another term used to describe the impeller used on a torque converter
Pump
What type of stator tends to be found in heavy-duty truck torque converters
Rotating
What usually connects a torque converter turbine to the transmission input shaft
Splines
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
Technician A
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
Technician B
Which of the following components is locked to the front cover of a torque converter during the lock-up phase and not otherwise
Turbine
Which of the following is the output or driven member of a torque converter assembly
Turbine
In which of the following phases of torque converter operation will torque be multiplied
Vortex flow
