This turbocharger is driven by exhaust gas to force compressed air into the intake manifold of the D0836LE501 engine. It increases the density of the air charge, allowing the engine to burn more fuel per cycle and produce higher power output. The set includes the necessary gaskets for reinstallation. A failing turbocharger typically presents as a loss of engine power, increased exhaust smoke, or a whistling noise from the rotating assembly. The manufacturer's original machining tolerances for the shaft and bearing housing are critical to maintaining the correct oil clearance and preventing premature bearing failure.
