Repair and operation of the car

To clean and check of a condition of a head of cylinders

Cleaning

ORDER OF REALIZATION

1. The scratch had been all the aspects of the material of old placing and selante of the inter-connected surfaces of a head of cylinders, the oil pipeline of entry and a final collector – tries not to damage surfaces. The application of a special razmyagchitel that must impregnate deposits previously pricked will make easy significantly the work. 2. Withdraw all the aspects of a foam of walls of water channels. 3. A rigid wire brush carefully clean all the available cavities and openings. In the moment of the strong pollution of channels the clearing of a head must be accused to experts. 4. Each one of very fast openings "banishes" the convenient faucet for the size, when withdrew products of corrosion, aspects of the old man selante of a woodcarving and when restored the damaged circles. In the presence of the access to a fountain of compressed, light air openings, having withdrawn of them the shave and the small garbage. When it uses compressed air do not forget of putting wide eyes! 5. A wire brush smooths a woodcarving of pins of the fixation of coverings of the axle (axles). 6. Wash out a front solvent and carefully dry it. The use of compressed air will allow to reduce significantly the term of the drying and there will give an asseguramento of the quality of a clearing of cavities badly available and openings. The structures different from the removal of aspects of a deposit that significantly makes easy the implementation of the proceeding of the cleaning can be acquired in many shops of motor accessories. Remember that such ways normally are chemically aggressive and have to devote themselves with the observance of the measures seized the precaution, – strictly they join to educations of the manufacturers whom they give normally in the etiquette of a container. 7. Wash out the solvent of a yoke of the walk of valves and the coverings of the loads of the axle (axles), then carefully dry them. Try not to mix component in the course of the cleaning – it controls the marking of the relevance of details to the cylinders / valves. The use of compressed air will make easy significantly the implementation of the proceeding (do not forget of putting wide eyes). 8. Wash out in the solvent and carefully dry springs valvate, his plates and fine cookies of cutting locks. Try not to mix component. 9. Scratch had gone to most of the valves of deposits created in surfaces, soon a wire mouth to the electric furadeira finally smooths surfaces of nucleuses and plates of valves – looks that the valves were not mixed.

Check of a state

Before taking the decision on the necessity of the realization of the mechanical work of a head of cylinders, carry out the careful control of his state. Attentively to study the material affirmed in the true subsection, do the list of the component ones that need special attention.

Head of cylinders

ORDER OF REALIZATION

1. Attentively check a head of cylinders of the existence of aspects of the hole of cooling liquid, slits and other damages. The head of explosion is subject to the substitution without fail. In case of the lack of the confidence in the definition of a condition of a head, it is necessary to send it for the check to a workshop of the service of the car. If the repair is not possible, substitute an incorrect head. 2. Through the instrument of measuring of planeness and the probe of the check of type of lezviyny the inter-connected front surface of the existence of signs of the deformation (companion to see an illustration). If not the planeness will exceed the value admissible of standards (to see Specifications in the beginning of the present Chapter), the head has to be sent to an in favor point in a garage. 3. Check a condition of saddles of valves in each one of cameras of combustion. In case of the identification of cavities, slits, aspects of a progar, the head must submit to the repair of special recuperation which realization is on the outside of the qualification of the middle amateur mechanic and has to be entrusted to specialists of the service of the car. 4. Through the DTI to measure it of instrument appreciates the size of a play of side of nucleuses of valves in the captures of direction (companion sees an illustration). The valve has to be lifted on a saddle approximately in 1,6 mm. It is soon necessary to divide the size full of a thrashing of side of the valve in two to define a slit of the landing of the valve in the direction capture. Compare when they resulted from the calculations done to demands of Specifications. In the presence of doubts in the fairness of the definition of a condition of component ones, his check must be accused to experts of a workshop of the service of the car.

Valves

ORDER OF REALIZATION

1. Attentively check the surfaces of work of valves of the existence of signs of unequal use, deformations, slits, cavities and aspects of a progar. Point of estimate of operation of nucleuses of valves. Check if there are no slits in nucleuses necks. For valves of repercussion of rotation of a curve of nucleuses. One secures of lack of cavities and signs of the excessive use of faces of end (companion sees an illustration). The identification of some of the enumerated defects demands the delivery of valves of the repair of recuperation in a workshop of the service of the car. 2. The width of measure of a cylindrical part (the consolation) of a plate of each one of valves (companion sees an illustration). If the width of a consolation will appear less than the value stipulated in Specifications, substitutes the valve.

Component of valves

ORDER OF REALIZATION

1. The degree of estimate of the use of parts of face of each one of springs valvate, check springs to cavities existence. Measure the free spring length (companion sees an illustration) and compare when they resulted from measurements to Specifications demands. If the spring will be shorter than the lowest admissible limit, is sunk and is subject to the substitution. Also there checks the complaisance to demands standard of the effort, developed per springs (this work that is better to collect to experts of a workshop of the service of the car). 2. Establishment of each one of springs vertically in a flat surface, check the gravity of his tortsovka (companion sees an illustration). The springs with the violation of a tortsovka as well as that was sunk are subject to the substitution. 3. Check spring plates and fine cookies of his locks cut of existence of slits and signs of the use. All the details that are in a doubtful state must be substituted new to avoid the development of defects in the future. 4. In the considerable degree of the use of component ones of valves that is quite probable for the motor that needs capital repairs, join meetings valvate, establish them at the regular places in a head and it passes to artistic proceedings of the service of valves (to see the Service of valves).
