Revolving component involved in the transmission of power from the engine to the drive wheels
What is Drive train
100
This can be identified as tiny indentations high on the shoulder or in the valley of the bearing raceway.
What is Brinelling
100
A rotating metal disc mounted to the rear end of a crankshaft. Used for standard transmissions
What is Flywheel
100
Surfaces scratched, cut gouged or grooved.
What is Abrasive
100
caused by high temperatures and overload, crack begins internally and moves outward, metal fatigue and rear is prominent.
What is Ductile, Fracture Failure
200
This is a gear driven or forced to turn by another gear
What is Driven Gear
200
Progressive destruction of shaft or gear teeth material
What is
Fatigue failures
200
A rotating metal disc mounted to the rear end of a crankshaft. Used for Automatic transmissions
What is Flex Plate
200
Surfaces melt and stick together
What is Adhesive
200
caused by sudden shock or impact signs are rough surfaces with little wear
What is Brittle, Fracture Failure
300
A wheel with internal or external teeth that serves to transmit or change motion
What is Gear
300
Occurs as a result of vibration when the outer race of a bearing picks up the machined pattern of the bearing bore
What is Fretting
300
a device that connects or disconnects power source from the part it operates to provide a smooth transition of torque to working parts in movement.
used on standard transmissions
What is Clutch
300
Surfaces show signs of pitting, rusting and scaling
What is Corrosive
300
interval time between oil and filter change too long or depletion of additives
What is Degradation, Lubrication Failure
400
the number of revolutions the driving gear must make to turn the driven gear one revolution
What is Gear Ratio
400
Surface irregularities caused by corrosion due to foreign material coming in contact with its surface.
What is Pitting
400
A fluid clutch used on automatic transmissions
What is Torque converter
400
Particles strike and break away smaller pieces
What is Erosive
400
presence of combustion by products, fuel or coolant, water, dust, dirt or gasses
What is Contamination, Lubrication Failure
500
Multiple keys in the general form of internal and external gear teeth
What is Splines
500
This occurs when metal is cropped off or displaced due to friction between surfaces
What is Galling
500
Last phase of a power train. it gives final reduction in speed and increases in torque to the drive wheels
What is final drive
500
Micro-welding and pitting result when two surfaces that are held together rub against each other
What is Fretting corrosion.
500
caused over time by part failure, signs are flat, smooth fractures and light color
