Regenerative repair of the engine The general information Far not always it is possible to define easily the moment when there is a necessity for carrying out of major repairs of the power unit. In attention the whole set of various factors should be accepted.Considerable run at all unessentially is a sign of that the engine requires major repairs. On the other hand, also it is impossible to consider the insignificant period of operation as a sufficient guarantee of a serviceable condition of the power unit. Perhaps, a major factor defining service life of the engine, frequency and a regularity of performance of procedures of the general and car routine maintenance is. At normal leaving the engine will reliably serve throughout many and many thousand kilometres of run whereas the careless relation to performance of procedures of routine maintenance together with a negligent manner of driving necessities of performance of major repairs of the power unit after very short term can already lead. It is possible to consider the excessive expense of engine oil as a signal about necessity of carrying out of check of a condition of piston rings, маслоотражательных caps and-or directing plugs of valves. Naturally, first of all, it is necessary to make sure, that oil losses are not connected with development of its external leaks. Address for the help to the qualified expert who will help to define the general condition of the engine of your car on the basis of results of check компрессионного pressure in cylinders and measurements of depth of depression at various initial parametres. Loss of developed capacity, infringement of stability of turns, excessive noise background клапанного the mechanism, the raised expense of fuel usually are characteristic enough signs of necessity of performance of major repairs of the engine, in particular, when all these factors are shown simultaneously. If performance of a full spectrum of options does not help with elimination of problems, carrying out of the general mechanical works on engine restoration will be a unique way out. Major repairs of the power unit mean restoration of all its working parametres to level, characteristic for the new engine. During major repairs replacement of piston rings and restoration of mirrors of cylinders (проточка and-or хонингование) is without fail made. In case of performance проточки cylinders selection of pistons of the corresponding repair size is made. Replacement radical and шатунных bearings is usually carried out, can be in case of need made проточка and restoration of necks of a cranked shaft. Service of the valves which condition at the moment of occurrence of necessity for performance of major repairs of the engine almost for certain leaves much to be desired is without fail carried out. In parallel with carrying out of the general repair of the power unit regenerative repair of such auxiliary components, as a starter and the generator is usually made also. As a result of repair engine parametres come back to the values peculiar to the new unit, thus last can serve smoothly still many and many thousand kilometres of run.
Before to start performance of major repairs of the engine, attentively familiarise with materials of the present Part of the Head for the purpose of theoretical preparation for forthcoming work. We will notice, that engine major repairs at all do not demand from the executor of high vocational training, however take away a lot of time. It is necessary to plan refusal of using the car for the term of not less than two weeks, in particular in need of the reference behind the help in a mechanical workshop for the purpose of performance of separate regenerative works. Spend small marketing, having checked up presence on sale of required spare parts, tools and the equipment. Beforehand prepare all necessary materials. The most part of works can be executed with application of a usual set of the metalwork tool, however some of checks by definition of suitability of separate components to further use demand application of the precision measuring equipment. In doubtful situations address for the help to experts of a workshop of car-care centre who always will help you to be defined with the decision on necessity of replacement or regenerative repair of any internal component of the engine.
In summary we will notice, that all efforts on performance of regenerative repair of the worn out components will appear spent for nothing at the negligent relation to the requirement of observance of cleanliness at unit assemblage. |
