1. Having removed a turbocompressor from the engine, make visual survey of its casing, checking it for existence of cracks and other visible mechanical damages.
2. Check freedom and smoothness of rotation of a shaft of a turbocompressor, manually turning one of assembly wheels. We will allow an insignificant side play as in work the shaft is hung out on an oil pillow. Check an external condition of turbine shovels of both wheels.
3. On turbocompressors like KKK the actuation mechanism of the waste gate is built in assembly and is not subject to check or replacement in an individual order. On Garrett system compressors the device is installed by the separate block and performance of check of its state / replacement should be charged to qualified specialists of car service.
4. Presence of oil in final or induction canals with high probability demonstrates failure of epiploons of a shaft of the turbine. And, if oil is present from the induction party, it inevitably gets as well to the built-in cooler (Intercooler) which in this case should be washed out solvent.
5. Performance of recovery repair of a turbocompressor lies outside qualification of the average amateur mechanic. The failed assembly can always be exchanged on new or restored.
