Definition of Part Numbers Status Codes (May 15, 2004)

Due to the Fact that Garrett has been building turbochargers for 50 years, there is now an immense range of part numbers to deal with.

We will explain briefly the different categories of parts that exist along with the different ways of servicing them when they are no longer in current production.

• TURBOCHARGERS : According to their age and population in the market the following situations could present themselves.
  1. In production : The turbocharger is in production and the availability depends only on the time to build and deliver.

  2. In production but substituted by another : This is the case where a technical design improvement has been made, normally the turbocharger has the same part number but a different dash, for example 454135-0002 substituted for 454135-0010. These substitutions can be seen in Garrett’s catalog. Sometimes, a completely different part number may be used and in either case, it will be shown as “Service with xxxxxx-xxxx”. This means that it is a Direct Service Replacement for the old part.

  3. Obsolete : Due to the age of the turbocharger or insufficient market demand it is no longer produced. The only way to service these units is by repairing them, or substituting them for reconditioned turbochargers.

  4. Exclusives : Garrett has signed exclusivity agreements with some manufacturers such as Caterpillar, Navistar, Detroit Diesel, Toyota, etc... , so that there is no authorization to sell these turbochargers through their distributors. In some cases, only the complete turbocharger is exclusive and some cartridges and other parts are available, in other cases such as Toyota all parts are exclusive. In this case we recommend repairing the turbochargers if possible or replacing them for reconditioned turbochargers.

• PARTS : In the case of parts, although the turbochargers are in production they are not all available for sales.

• Variable Nozzle Turbochargers : None of the parts are available for sale ( only the complete turbochargers are available ) due to the fact that instruments do not currently exist in the market for the correct calibration of the valves of these turbochargers.

• Electronic Actuator Turbochargers : None of the parts are available for sale ( only complete turbochargers are available ) due to the fact that instruments do not currently exist in the market for the correct calibration of the valves of these turbochargers.

• Ball Bearing Turbochargers : The smallest service part available is the cartridge, due to the fact that the high technology used in its development is not available in the repair market.

• GT Series : Due to the large variation in parts that exist only the most popular parts are sold.

• T Series : Many of the parts of turbochargers that are more than 20 years old are no longer available, although most of the rest are still available.
