Options of restoration of the engine

At independent performing procedures of capital repairs of the engine the amateur mechanic will face a possibility of implementation in its several various ways. The first of criteria by which need of carrying out replacement of the block of the engine is determined conrod and piston assemblies and a bent shaft is the condition of the block of cylinders. Material inputs, existence of access to the machine park, definition of the list of necessary spare parts and a possibility of their acquisition are among other factors. Besides, necessary conditions are existence of free time and experience of independent performance of mechanical works.

The cost of carrying out the listed below alternatives of capital repairs of the engine can vary depending on quality of the acquired spare parts, extensiveness of a range of necessary machining and required for high-quality performing procedures of the special tool and the equipment. Many automobile repair shops in addition to repair of separate components undertake performance of full assembly of the engine (with installation of the full or reduced set). Consult in the nearest auto repair shops about a range of the works performed by them and the prices of them.

Are main of options of restoration of the engine:

Replacement of separate components - If the preliminary analysis of a condition of the engine showed that the block of cylinders and the most part of components of the engine are in a state, suitable for further application, acquisition and installation only of separate defective components can be the most reasonable and economical way out. At the same time conditions of the block, a bent shaft and conrod and piston assemblies have to be checked very carefully. Even at insignificant degree of wear of the block without fail it is necessary to make a honingovaniye of cylinders.

Installation of the reduced set of the block - the Reduced set consists of the engine block complete with a bent shaft and conrod and piston assemblies. At the same time all new bearings have to be installed and all gaps are exposed. On such block after insignificant (if it is required) machining the old camshaft, components of the valvate mechanism, a head (i) of cylinders and hinged units are installed.

Installation of a totality of the block - Full set includes the reduced set, plus the oil pump, the case pallet, a head (i) of cylinders, a cover (and) heads, the camshaft and components of the valvate mechanism, distributive asterisks with a chain or gear wheels and a cover of the drive of the gas-distributing mechanism (chain). All components are installed with new bearings, epiploons and laying and everything that is required to be made, it to install the inlet pipeline, a final collector(s) and hinged units.

Carefully weigh everything pros and cons at the choice of option of restoration of the engine, consult in a local workshop of car service or dealer office and only then start purchase of necessary spare parts.
