It is most easier to assort the engine and to make all types of works at the figurative stand which has been specially intended for repair of the engine. Such stands can be hired often. Before engine installation it is necessary to shoot a flywheel with the stand with the coupling mechanism (or a leading disk of the hydrotransformer), and also the holder of a back epiploon of the crankshaft.

If the stand is not present, to assort the engine it is possible having strengthened it on a strong workbench or on a floor. When dismantling without use of the stand be very careful during manipulations with the engine.

If you get the ready engine of repair completeness, at first it is necessary to remove all hinged units to establish them subsequently precisely in the same order as well as at independent major maintenance. Such units treat:

 – generator and arms;
 – details of system of decrease in toxicity of exhaust gases;
 – distributor of ignition, candle and high-voltage wires;
 – thermostat and cover of the case of the thermostat;
 – the pump of cooling liquid and other details of system of cooling;
 – details of electronic injection of fuel;
 – inlet and final collectors;
 – oil filter;
 – engine mount details;
 – flywheel (or leading disk of the hydrotransformer);
 – back assembly flange.
Prevention

At removal from the engine of hinged units, with special attention treat those details which can be necessary at engine assembly. Put labels on laying, epiploons, remote plugs, pins, bolts, washers, nuts, etc., to establish them in former situation.


If the block of cylinders of an incomplete complete set (i.e. the block of cylinders with established by the krivoshipno-shatunny mechanism and piston group) is established, it is necessary to remove also a block head, the oil pallet and the oil pump then with the krivoshipno-shatunny mechanism and piston group it is possible to hand over the remained block of cylinders in repair.

If it is planned to carry out major maintenance with complete dismantling, the engine it is necessary to disassemble and remove completely engine details in the following order:

 – soaking-up and final collectors;
 – cover of a head of cylinders;
 – covers of a gear belt;
 – head of the block of cylinders;
 – oil pallet;
 – oil pump;
 – shatunno-piston group;
 – holder of a back epiploon of the crankshaft;
 – the crankshaft with radical bearings.

Before dismantling and performance of procedures of major maintenance be convinced, available all necessary equipment and the tools which list is provided below. (The list of tools which will be necessary at assembly is provided in subsection 3.1.2.15.)

 – standard set of the tool;
 – small cash desks or plastic sacks for storage of the removed details;
 – a shpatel for removal of the remains of laying;
 – development for removal of fillets from cylinders;
 – micrometers;
 – set of sliding measuring instruments;
 – set of display nutromer;
 – the adaptation for compression of springs of valves;
 – the adaptation for a honningovaniye of cylinders;
 – the tool for cleaning of flutes of piston rings;
 – electrodrill;
 – set of taps and dies;
 – wire brushes;
 – ершики for pro-cleaning of oil channels;
 – solvent.
