Motor Mechanic (Light Motor Vehicle Motor Mechanic)



Light motor vehicle mechanics service, repair and overhaul the mechanical parts of motor vehicles such as the engine, the transmission (clutch, gear box and differential), and the suspension systems (springs, steering, brakes, wheels and tyres).

Light vehicle motor mechanics work mainly in workshops and wear protective clothing. They need to keep up with changes in motor industry technology.

With the changes in automotive t ....etc
