4.15. An order of dismantling of the engine by its preparation for major repairs
The scheme of an arrangement of hinged units
Design of the block of cylinders
Most easier to carry out engine dismantling, having established it on the portable assembly stand. The such adaptation always can be borrowed rather cheaply in a car-care centre workshop. Before to fix the engine at the stand, it is necessary to remove from it a flywheel / приводной a disk.
If possibility to take advantage of the stand is absent, dismantling should be made, having placed the engine on a strong workbench, or reliably having arranged it on firm to a garage floor. At work without the stand watch that the engine casually has not overturned.
If it is planned to make replacement of the engine on restored, remove with old all hinged units and external components and transfer them on the replaceable block. In number such, subject to shift, components enter (illustrations the Scheme of an arrangement of hinged units and the Design of the block of cylinders) see:
- The generator with arms;
- The steering pump with arms;
- Components of systems of decrease in toxicity of the fulfilled gases;
- The distributor, ВВ wires and spark plugs;
- The thermostat with a casing cover;
- Perepusknoj branch pipe / a hose of the water pump;
- Components of system of injection of fuel;
- The inlet pipeline and final collector ();
- The oil filter
- Support of a suspension bracket of the power unit;
- Flywheel / приводной a disk.
At removal from the old engine of external components try to remember prominent features of their installation. Fix in a notebook landing positions of linings, epiploons, remote rings and plugs, pins, arms, washers, bolts and other fine details.
At a choice of the scheme with use of the reduced set of the block consisting of the block of cylinders with established in it by cranked shaft and shatunno-piston groups, remove from the old unit also a head of cylinders, the pallet картера and the oil pump (alternative variants of schemes of performance of major repairs — see Alternative variants of schemes of regenerative repair of the engine).
At carrying out of full major repairs of the old unit, make its dismantling and take all internal components. The optimum order of performance of procedure of dismantling of the engine is more low resulted:
- The inlet pipeline and final collectors;
- Covers of heads of cylinders;
- Covers of drive ГРМ with bolts;
- Drive ГРМ (газораспределительный a belt with cogwheels);
- Assemblages коромысел and camshafts;
- Heads of cylinders;
- The water pump;
- The pallet картера;
- Маслозаборник with the mesh filter;
- Forward cover / the oil pump;
- Assemblage of covers of radical bearings;
- Shatunno-piston assemblages;
- Cranked shaft and radical bearings.
Before to start engine dismantling, prepare following materials, tools and details (the engine Assembly order see also):
- Standard set of the metalwork tool;
- Set of cardboard or plastic containers / of polyethylene packages for the organised storage of small components;
- Scraper for зачистки interfaced surfaces;
- Vertical drill for removal of step deterioration in the top part of cylinders;
- Stripper for dismantle демпфера крутильных fluctuations;
- Set of micrometers;
- Telescopic нутромер;
- Tsiferblatnyj measuring instrument плунжерного type (DTI);
- The tool for compression клапанных springs;
- Хон for processing of mirrors of cylinders;
- The tool for procleaning of flutes under installation of piston rings;
- Set of taps and лерок;
- Wire brushes;
- Cylindrical brushes for procleaning of oil galleries;
