Good advice on carrying out regenerative repair of the engineGeneral information
The most part of procedures of major and regenerative maintenance of the engine is among the so-called standard. It is necessary to give special attention to strict observance of requirements of Specifications for the concrete engine. A lot of things depends also on qualification of the performer. Originators of the real Management recommend the following approach for preparation and performance of regenerative repair of the engine:
· The owner of the car can independently make dismantle, cleaning and check of a condition of components;
· After acquisition of necessary replaceable details it is necessary to deliver all removed elements in a car-care center workshop where preparation for installation and assembly of knots will be made by strengths of the qualified experts;
· The most part of assembly procedures (installation of a cranked shaft, bearings, shatunno-piston assemblies and so forth) also can be made by own strengths of the owner under condition of existence of necessary tools.
Before starting to work, try to define for yourself a range of works which you will independently make.
Number of the tools which use is a necessary condition of performance of complete major maintenance of the engine treats the following:
· Standard set of the metalwork tool;
· A set of cardboard or plastic containers / plastic bags for the organized storage of small components;
· Set of strippers of screw and nozhechny type;
· A scraper for cleaning of interfaced surfaces;
· The tool for compression of klapanny springs;
· The tool for pro-cleaning of flutes under installation of piston rings;
· The tool for removal and installation of piston rings;
· A special vertical drill for removal of step wear from walls of cylinders;
· Hon for processing of mirrors of cylinders;
· Set of micrometers;
· Telescopic nutromer;
· Tsiferblatny measuring instrument of plunzherny type (DTI);
· Plastigage set for definition of working gaps in bearings;
· The portable assembly stand for fixing of the engine removed from the car it (is desirable).
· Set of taps and lerok;
· Wire brushes;
· Cylindrical brushes for pro-cleaning of oil galleries;
Sometimes there is a need for use of some special tools which identification number in similar cases is specified in the text of the description of the corresponding procedure.
The materials used for manufacturing of knots and details of the power unit
Recently the increasing popularity in automotive industry, in a type of the low specific weight, is gained by aluminum. At service of aluminum details it is necessary to observe some special precautionary measures:
· Do not use for cleaning of aluminum details the aggressive solutions which application can lead to an alloy erosion;
· Before dry cleaning of the power unit remove from it all components made of aluminum;
· In order to avoid "prikhvatyvaniye" rolled in details of fixture made of aluminum previously grease its carving part with engine oil, or anti-taking hermetic;
· Try not to allow tightenings of the fixture rolled in aluminum components, with excessive effort, - watch observance of requirements of Specifications.
At unit assembly its moving internal components it is necessary to grease all before installation by the special greasing, a providing sparing mode of their operation at primary start (impellent oil is not necessary for greasing of such components).
For fixing of carving fixture subject to raised vibrating loadings it is necessary to use special not stiffening hermetic of the Loctite® type.
Before starting check of a condition of components of their engine it is necessary to clear carefully. Remember that cracks in molding of a block/head of cylinders can be looked through under a layer of these components of deposits inevitably present on a surface, a scum and a deposit.
Cleaning of components can be made with use of the ordinary metalwork tool and different solvents and детергентов. The main layer of coal deposits usually is removed by a skalyvaniye a special wooden chisel. The deposit and traces of a material of old laying act in film by means of a scraper and solvent. For removal of especially firm deposits it is possible to use special nozzles to an electrodrill, however, it is necessary to operate extremely carefully casually not to damage prokladochny surfaces, beds of bearings and a mirror of cylinders.
Try to adhere always to instructions of manufacturers of cleaners and tools. Do not forget about need of use of goggles and gloves.
Before cleaning of the block of cylinders take from it all caps provided by a design, vyzhimny jams and the pressed bearing loose leaves. For washing of remote cavities, galleries and маслотоков use special brushes.
Do not forget that all smallest components of the unit, including fixture and springs should be subject to reading. For dissolution of traces of corrosion and different deposits fine details should be placed previously in an oil bath.
Special attention give to deposit removal from the bottoms of pistons from flutes under installation of piston rings.
When cleaning a head of cylinders carefully remove coal deposits from walls of chambers of combustion.
In the absence of full confidence of the forces it will be reasonable to charge performance of cleaning of components of the engine to specialists of car-care center.
Restoration of the damaged carving openings
Twisted inserts under carving fixture of standard (American) and metric (European) type are issued. Separate inserts are applied to carving restoration in candle openings. Inserts are equipped with the special lock uvulas providing their fixing on the landing tool at installation. After an insert vvorachivaniye the uvula is bitten.
The structure of a typical set for restoration of carving openings includes a set of twisted inserts, a tap corresponding to an external carving of inserts and the adaptation for landing of inserts in an opening. Sets for carving restoration in candle openings differ from usual in view of need of application of taps with directing rounds and a razzenkovyvayushchy forward side a little. Sets are surely accompanied by the detailed instruction on application. In the absence of confidence of own forces do not hesitate to address for the help to specialists of car-care center.
For extraction from carving openings of the "become attached" fixture usually are used самоконтрящиеся nippers, - before a reversing it is necessary to impregnate fixture with getting structure.
