Rule N1: even on think of repair турбокомпрессора in house conditions.
In spite of the fact that details турбокомпрессора work at temperatures to 800 ° With and speeds in 50 000-85 000 turns in a minute, they are reliable enough. However and they wear out and grow old, and the first units of a turbo-supercharging (they became really mass 5-7 years ago) already fail and, sometimes, it is accompanied by serious consequences.
However, not always it is necessary to blame турбокомпрессор that the engine suddenly began to lose capacity. The banal collar which weakened and has flied from the pipeline, or the punched consolidation can become the reason for it.
More often, nevertheless, the reason of decrease in capacity of the power unit is faulty турбокомпрессор. It is not necessary to try to repair it, and here to replace it quite under force on the majority of widespread cars.
The most difficult – "the charged" sports models, especially what are equipped double турбонагнетателями among which it is considered one of the most difficult Audi S4. Standard work on their replacement at the dealer at this case is calculated at 12 o'clock. For models of such complexity it is recommended even not to think of repair in house conditions, and many of professionals refuse to undertake it if have no complete set of necessary tools and adaptations.
Nevertheless, it is not necessary to give in and in advance to surrender. On the majority of models replacement турбокомпрессора can be made independently. The motor compartments overflowed with units with the limited access to the engine will be the main problem. Sleight of hand and a S-shaped key will help here better any special tools.
As well as any work on repair, replacement турбокомпрессора demands concentration and methodicalness. Начинте that release access to units from pipelines, wires and other auxiliary knots. An empty seat it is required to you much, as it will be necessary to remove four (sometimes – three) nuts of a final collector, the reception pipe, three pipelines of giving and oil plum, and all pipelines of giving of air. turbochargerы with water cooling it is even more difficult because of additional details.
One of inevitable partners in life турбокомпрессора – high рабочиетемпературы. Thereof fastening nuts "are welded" on a final collector almost tightly and it is required to apply a significant amount of a preparation of type WD 40 before the beginning of work with them. After replacement of the main unit it is necessary to replace without fail nuts on new, made of stainless steel. If they are from a usual steel next time, possibly, to turn off them it will be almost impossible.
Hairpins can be turned on some turns at untwisting of nuts, or even to be turned out completely. Carefully check up, whether has occurred warps and carving damage. If the such has occurred – restore a carving and wrap hairpins into place against the stop.
Not all designs турбокомпрессоров provide a sealing lining in a junction with a final collector. Therefore be not surprised, if you have not found it at dismantle of this unit on your car. If the lining all the same was, necessarily establish new at the subsequent assemblage.
Having removed турбокомпрессор, check up all released маслопроводы. For this purpose ask someone to include a starter (having removed high-voltage wires from the engine to exclude possibility of its start-up), and be convinced that oil moves freely. Having established new турбокомпрессор, do this procedure once again that oil has arrived to its bearings prior to the beginning of the "present" work. Bearings турбокомпрессора without oil – even for a second this worst that he can test in the life!
