⚙️ Key Features

• For engines up to serial number 147401
• Inlet and Exhaust System group
• 17.962 kg
• 30 applications across TD, TWD, TID and TAD

🔌 Function

Uses the exhaust gas to drive a turbine and compressor on a common shaft, forcing more air into the engine than it would draw on its own.

⚠️ Common Signs of Failure

• Loss of power with black smoke under load
• Whine, whistle or a rising screech that was not there before
• Blue smoke and oil consumption with oil found in the charge pipework
• Shaft play felt when the wheel is rocked, or blade tips rubbing the housing
• Oil leaking from either the turbine or compressor end seal

🛠️ Service Notes

• Check the engine serial number against the 147401 break before ordering
• Find out why the old unit failed before fitting a new one — oil supply, oil quality and air filtration are the usual causes and they will kill the replacement too
• Prime the new unit with clean oil and idle the engine before loading it
