Repair without extraction from the car of the petrol engine of 1.3 l Engine cross-sectionLongitudinal section of the engine Instructions for use Head's material This Part of the Head is devoted to the repair of the petrol engine of 1.3 l which is not connected with its extraction from the car (in situ). The description of the most part of the considered procedures is made, proceeding from the assumption that the power unit remains on the regular place in a motive compartment of the car. In view of told in case the engine is already dismantled and installed on a workbench or the assembly stand, many of the described steps have to be lowered. Let's notice that despite physical capacity of performance of repair of in situ of such components as conrod and piston groups, works of this sort are usually performed after dismantling of the engine in view of need of holding some auxiliary procedures, not to mention requirements to respect for purity of details and absolute passability of maslotok. General description of the engine The considered engine concerns to family of 4-cylinder petrol engines with line placement of cylinders and the top arrangement of valves (OHV). Cross and longitudinal cuts of the engine are presented on illustrations. The engine is installed cross in a forward part of the car and inclined forward at an angle 20 °. Assemblies of transmission and coupling are in the left part of the power unit. The block of cylinders, head and cover of a head are cast from aluminum alloy. The lower part of cylinders gilzutsya by inserts of iron casting. The bases of sleeves are equipped with sealing laying in order to avoid penetration of cooling liquid into the case pallet. The bent shaft is installed in three radical bearings. A flywheel with assembly of coupling fasten to a flange at the left end face of a shaft. The forward end of a bent shaft is equipped with an asterisk for installation of a two-row chain of the drive of the camshaft. Radical and conrod bearings have a demountable design and are equipped with two inserts. In the top head of a rod the bronze plug deployed under landing of a piston finger is pressed. The right end of the camshaft is equipped with a spiral gear wheel of the drive of the distributor of ignition. The drive of the oil pump is also made from the camshaft through a distributor axis. The compulsory lubrication system of the engine is organized by means of the gear pump which is taking away oil from the case pallet through the maslozabornik equipped with the mesh filter and giving it to internal components of the engine previously banishing through the full-line oil filter of replaceable type established outside in a forward part of the block of cylinders. In spite of the fact that the engine is not high-speed and does not differ in big power, it provides to the car quite decent dynamic characteristics. Thanks to the fact that the engine is not overloaded, on condition of use high-quality oils and fuels it differs in the increased reliability and durability.
The list of repair procedures which implementation does not demand extraction of the engine from the car Procedures of repair and service of the engine which implementation can be made by in situ are listed below: a) Removal and installation of a belt of the drive of auxiliary units; b) Removal and installation of a cover of a head of cylinders; c) Removal and installation of assembly of yokes; d) Removal and installation of a head of cylinders; e) Removal and installation of a cover of a chain of the GRM drive; f) Removal and installation of a chain of the GRM drive with asterisks; g) Removal and installation of the oil cooler; h) Removal and installation of the oil pump; i) Removal and installation of the pallet of a case; j) Decarbonization of a head of cylinders and pistons; k) Replacement of epiploons of a bent shaft; l) Removal, check of a state and installation of a flywheel; m) Check of a state and replacement of support of a suspension bracket of the power unit; |
