Turbo And Lubrication Of Bearings

Posted Jan 12th 2011 8:24AM


Lubricating oil inside the turbo shaft is not too difficult, and most of the turbo enough oil supplies to the bearing axis. However, the extremely high temperatures that the turbine housing creates a cause of bearing oil disintegrate and lose viscosity and lubricating properties and cause coking in the turbo bearing housing. Coking stop the oil bearing and makes the problem worse. Four things contribute to coking coal:

  • The high temperatures are the bearing housing of the turbo
  • Use of motor oil can not operate at high temperatures
  • Use of motor oil, which is a large multi-grade oil in the area – of the additives used to obtain multi-grade oils are the material, which results in coke
  • Do not change engine oil often enough.

There are two easy solutions to this problem:

  • Change engine oil more frequently
  • Get a water jacket around the turbo bearing housing. It might be a good idea to watch out for water jacket around the choice of the bearing turbo turbo

Best motor oil can be used in its turbo engine is a synthetic oil, the viscosity law that is suitable for the temperature range of both climate in the region in which they live, and the engine.

The important thing is to change the engine oil and oil filter regularly. Even if the turbo has a water jacket around the bearing housing, always change the engine oil more frequently than naturally aspirated engines, and you have to do due diligence! Change engine oil every 2,000 miles must do the trick.

You must also ensure that the oil pressure of the turbocharger does not exceed 70 psi or more that oil will go beyond the oil seals in the turbo and common cause, if not smoking consistently. If your oil pump produces more oil than the pressure of the turbo seals can handle, you must install an opening in the oil supply line or a bypass system to reduce the oil pressure and turbo. A bypass system is more reliable, but in both cases, you must ensure that the oil pressure, turbo enough at idle and at full operation.

Turbo oil seals will not work properly if they are in an oil bath should be ensured that the oil return line of the cup is large enough to allow proper drainage. oil return pipe must have an internal diameter of at least half an inch. the oil drain hole in the turbo system must be aligned as closely as possible in a downward direction as possible.

The best way to ensure that the Turbo takes you to a cruise at low speeds, without the boost pressure is created in the last 15 minutes to cool down the turbo. Some suggest that you let the engine idle for 30 seconds before turning off the engine, or install a turbo timer to automate the task, but the oil pressure at idle speed is too small for proper lubrication. You need at least 1500 rpm, oil pressure enough for the bearings and shaft may be sufficient lubrication when the turbo is cooled. E ‘for this reason, we recommend installing the turbo timer. You should also change the engine oil every 2000 km, and high-quality, synthetic oil direct viscosity. These three simple things to make sure you extend the life of the turbo, and not have to worry about coked up to the failure of the new bearing turbo.
