🔌 Function

Uses exhaust gas energy to spin a compressor that forces extra air into the inlet, raising power output and improving combustion.

⚠️ Common Signs of Failure

• Black smoke, sluggish pick-up and a clear loss of power
• Whistling, whining or rumbling that rises and falls with engine speed
• Oil in the inlet pipe or exhaust elbow, with rising oil consumption
• Shaft play, or rub marks on the compressor wheel and housing
• Coked or restricted oil feed line to the bearing housing

🛠️ Service Notes

• At 15.1 kg this is a two-hand lift — support it while offering it up and renew the gaskets and nuts on both flanges
• Always establish why the old unit failed: renew the oil feed and return lines and prime the bearing housing before the first start
• Turbocharger 844034 is the 8.06 kg unit listed for the TD and TID series, so confirm which fits before ordering
