Application
This unit of competency defines the skills and knowledge required to diagnose, repair and replace diesel engines used in mobile and stationary plant and equipment.
It covers the diagnosis of diesel engine operation to determine location and cause of faults and whether in situ repair, more specialist investigation or engine removal for off-site repair is required. It includes bottom and top end repair of engines and re-installing repaired or replacement engines into stationary and mobile plant.
Where repairs to fuel, coolant, electrical and starting, exhaust systems, as well as transmissions and accessories and their components are required, see the appropriate units.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Band: A
