• 5 applications across TWD, TD and TAD series engines
• Inlet and Exhaust System group

🔌 Function

Uses exhaust gas to spin a turbine and a compressor wheel on a common shaft, forcing more air into the cylinders so the engine can burn more fuel for the same swept volume.

⚠️ Common Signs of Failure

• Blue or black smoke, particularly under load
• A whistle, siren or grinding note from the turbine that changes with boost
• Loss of boost, sluggish pick-up and poor top-end power
• Oil in the inlet pipework or standing in the charge air cooler
• Shaft play felt at the compressor wheel, or wheel tips rubbed on the housing

🛠️ Service Notes

• Renew the oil feed and return pipes and prove both are clear before fitting
• Establish why the old unit failed - a starved, dirty or restricted oil supply will destroy the replacement in the same way
• Prime the bearing housing with clean oil and crank without starting before the first run
