Manual Extract: Causes of Premature Turbocharger Failure

It is crucial to identify and address conditions that may lead to early turbocharger failure. Repairing the failure alone is insufficient; determining its underlying cause is essential to prevent repeat failures. Below are some common causes of premature turbocharger failure:

Lack of Lubricating Oil

Insufficient oil supply can result in inadequate lubrication or cooling of bearing and journal surfaces, leading to turbocharger failure. The volume of oil required increases with turbocharger speed and engine load. Note that insufficient oil for even five seconds can cause failure, emphasizing the importance of priming the turbocharger as part of routine operations. Ensure that proper lubrication reaches the turbocharger bearings before operating the engine at its rated speed to prevent damage.

High Exhaust Temperature

Excessive exhaust temperatures can cause lubricating oil to coke in the center housing drain annulus at the turbine end, leading to oil leakage and carbon deposits, ultimately damaging the turbine wheel. Additionally, high exhaust temperatures can erode the turbine housing, causing pitting and deposits on the turbine wheel. Sometimes, the turbocharger itself may cause high exhaust temperatures due to severe carbon build-up, which slows the rotating assembly and reduces inlet air flow.
