The General Process

First and foremost, rebuilding a turbocharger helps us understand why your turbo failed and this is an important piece of knowledge. When we take a turbocharger apart, we find out a number details about the general condition of the parts, the appearance, as well as the wear on various internal components. We also learn about your driving habits, how well the oil you use is really functioning for your vehicle, and how your maintenance schedule is working or not working for your turbocharger.

One of the details that pleases people the most, is that a rebuild will save you a great deal of money. The average rebuild can cost around less than half of what a new turbocharger might cost.

What happens during a turbocharger rebuild?

  1. First, the turbo is taken apart and thoroughly inspected. New seals, gaskets, and bearings are usually part of putting the turbocharger back together.
  2. Clearances, including bearing and seal journals, housing bores, wheel dimensions, collars, seals, and bearings, are all usually measured.
  3. A careful balancing procedure, including checking, correcting, and rechecking is performed to rectify imbalances that inevitably occur when the new thrust collar assembly is installed.
  4. All the parts are very thoroughly cleaned. Every tiny detail matters in a precision device like a turbocharger. Small amounts of dirt or carbon, even a speck, can cause quick and severe damage, which will reduce the life of your rebuilt turbo.
  5. Every bolthole, fitting, thread, and gasket surface is carefully inspected to ensure it is in proper working order. Any damaged hardware is replaced and all fittings are sealed to ensure your turbocharger will be trouble free upon installation.
