Turbine Shaft & Wheel – Broken Turbine Wheel Base This image shows a damaged turbine wheel base – look closely and you can see that the base has several sections cut out of it, which have been chipped off. Damage like this is caused by excessive thrust bearing wear, which has caused the turbine wheel

Bearing Housing – corrosion damage Here you can see an example of bearing housing corrosion . Corrosion damage like this results in a loss of seal between the bearing housing and turbine housing, and can cause a series of knock on effects, including damage to the bearings, turbine, compressor wheel, and housing. This kind of

Turbine Shaft & Wheel – Corroded Piston Ring Seal Area In this image, you can see some moderate corrosion to the piston ring seal area of the turbine shaft – the surface of the metal has become worn, pitted and roughened. A corroded piston ring can lead to major faults in your turbo and is

Bearing Housing – Carbonised Oil Blockage in the Galleries In this example, we’ll discuss how the bearing housing galleries can become completely blocked and choked up with carbonised oil (oil blockage). Whilst build up of oil in the bearing housing like this has a number of causes, the most common are a lack of regular

Turbine Shaft & Wheel – Worn Piston Ring Seal Groove This example shows a worn piston ring seal groove – in the image, you can see that the outer edge of the piston ring seal groove is sloping outwards, when it should be straight. This is fairly common, and has a number of causes. Sometimes,

Turbine Shaft & Wheel – Engine Failure This image shows a turbine shaft and wheel with fairly serious impact damage as a result of engine failure. If you look at the wheel itself, you can see that the blades are uneven and chipped, and that the surface of the wheel has become severely pitted. In
