Good advice on carrying out of regenerative repair of the engineThe general information
The most part of procedures of capital and regenerative repair 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. Much depends also on qualification of the executor. Composers of the present Management recommend the following approach to 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 centre workshop where preparation for installation and assemblage of knots will be made by forces of the qualified experts;
· the Most part of assembly procedures (installation of a cranked shaft, bearings, shatunno-piston assemblages and so forth) also can be made own forces of the owner under condition of presence of necessary toolkit.
Before to start to work, try to define for yourself a spectrum of works which you will make independently.
Number of the tools which use is a necessary condition of performance of full major repairs of the engine concerns the following:
· the Standard set of the metalwork tool;
· the Set of cardboard or plastic containers / polyethylene packages for the organised storage of small components;
· the Complete set of strippers screw and ножечного type;
· the Scraper for зачистки interfaced surfaces;
· the Tool for compression клапанных springs;
· the Tool for procleaning of flutes under installation of piston rings;
· the Tool for removal and installation of piston rings;
· the Special vertical drill for removal of step deterioration from walls of cylinders;
· Хон for processing of mirrors of cylinders;
· the Set of micrometers;
· Telescopic нутромер;
· Циферблатный a measuring instrument плунжерного type (DTI);
· Set Plastigage for definition of working backlashes in bearings;
· the Portable assembly stand for fixing of the engine removed from the car it (is desirable).
· the Electrodrill;
· the Set of taps and лерок;
· Wire brushes;
· Cylindrical brushes for procleaning of oil galleries;
Sometimes there is a necessity for use of some special tools which identification number in similar cases is underlined in the text of the description of corresponding procedure.
The materials used for manufacturing of knots and details of the power unit
Recently the increasing popularity in motor industry, in a kind of the low relative density, is got by aluminium. At service of aluminium details it is necessary to observe some special safety measures:
· do not use for cleaning of aluminium details the aggressive solutions which application can lead to alloy erosion;
· Before dry cleaning of the power unit remove from it all components made of aluminium;
· In avoidance “прихватывания” rolled in details of fixture made of aluminium preliminary grease its carving part with engine oil, or antitaking hermetic;
· Try not to suppose a tightening of the fixture rolled in aluminium components, with excessive effort, - watch observance of requirements of Specifications.
At unit assemblage it is necessary to grease all its moving internal components 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 type Loctite®.
Before to start check of a condition of components of their engine it is necessary to clear carefully. Remember that cracks in moulding of the block/head of cylinders can be looked through under a layer of given components of adjournment inevitably present on a surface, a scum and a deposit.
Cleaning of components can be made with application of the usual metalwork tool and a various sort of solvents and детергентов. The basic layer of coal adjournment usually leaves by скалывания a special wooden chisel. The deposit and traces of a material of an old lining act in film by means of a scraper and solvent. For removal of especially firm adjournment it is possible to take advantage of special nozzles to an electrodrill, however, to operate follows extremely cautiously casually not to damage прокладочные a surface, bed of bearings and a mirror of cylinders.
Try to adhere always to instructions of manufacturers of cleaners and tools. Do not forget about necessity of use of goggles and gloves.
Before cleaning of the block of cylinders take from it all provided by a design заглушки, выжимные stoppers and запрессованные подшипниковые loose leaves. For washing of remote cavities, galleries and маслотоков use special brushes.
Do not forget, that all most smallest components of the unit, including fixture and springs should be subject to reading. For dissolution of traces of corrosion and a various sort of adjournment small details preliminary should be placed in an oil bath.
Special attention give to removal of a deposit from the bottoms of pistons from flutes under installation of piston rings.
At cleaning of a head of cylinders carefully remove coal adjournment 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 experts of car-care centre.
Restoration of the damaged carving apertures
Twisted inserts under carving fixture of standard (American) and metric (European) type are issued. Separate inserts are applied to carving restoration in candle apertures. Inserts are equipped by the special lock uvulas providing their fixing on the landing tool at installation. After вворачивания inserts the uvula is bitten.
The structure of a typical set for restoration of carving apertures includes the complete set of twisted inserts, a tap corresponding to an external carving of inserts and the adaptation for planting of inserts in an aperture. Sets for carving restoration in candle apertures differ from usual in view of necessity of application of taps with directing coils and раззенковывающей a forward side a little. Sets are necessarily accompanied by the detailed instruction on application. In the absence of confidence of own forces do not hesitate to address for the help to experts of car-care centre.
For extraction from carving apertures of the "become attached" fixture usually are used самоконтрящиеся nippers, - before a reversing it is necessary to impregnate fixture with getting structure.
