"Remember - a turbocharger is a part of the engine, and it plays a very important part. A faulty turbocharger may cause damage to the engine,and if the engine is not operating properly, it may damage the turbocharger. Lack of lubrication, an overly low level of oil, failure to change the oil for too long, as well as dirt or filings suspended in it – all these factors may cause damage to the bearings and cause the rotating assembly to seize up. Turning off a hot engine too soon causes oil charring and carbon deposits in the turbocharger's lubrication system – over time the lubrication channels become clogged with carbon and the entire system seizes up due to lack of lubrication. In extreme cases, turning off a very hot engine leads to swelling of the material and breaking of the shaft, which is why it is advisable to wait for a few minutes to let the engine cool down before turning it off.

The reconditioning process

  • Disassembly of the turbocharger into its individual component parts,
  • washing and cleaning of all components,
  • checking and measuring the of the dimensions – in keeping with the model / manufacturer,
  • replacement of worn or damaged parts with new ones,
  • precision balancing of the rotating assembly,
  • re-assembly of the turbocharger,
  • inspection and possible adjustment of boost pressure.

Our policy is simple: all our used turbochargers pass a thorough review, where we find whether they are suitable for further use. If everything is in good working order, the turbo is cleaned and sold as a used item, but if we do find that one of the elements needs to be replaced, the turbocharger is additionally cleaned and sandblasted with special abrasive grit with very small grains, so that only accumulated dirt and rust are removed, and the item's structure remains intact.

After being thoroughly cleaned, all the parts are diagnosed further, to determine their usefulness, and all the elements responsible for lubrication and sealing are replaced with new ones. The shaft and wheel, and the compressor wheel, if they are in perfect condition and need not be replaced, are balanced within the minimum values using a high precision Schenck balancing machine. Then the rotating assembly is mounted in the bearing housing, and the entire core is then balanced at high speeds, up to 200 000 rpm, on a CIMAT balancing machine, where we can balance it with significantly more precision than what is required in the industry standard. As the conditions on a high-speed balancing machine are similar to those under normal engine operation, we can make sure of the efficiency and proper sealing of our reconditioned turbochargers. After balancing, the turbocharger is reassembled, and if it has variable geometry, it is then tested on a TurboTest machine, where we can adjust it to achieve factory settings. The latest turbocharger models have electronic tilt sensors or actuators. If necessary, they are replaced or repaired as well, if it is possible. For testing the electronics we use Delta-Tech or TurboTest devices.
