GENERAL INFORMATION

Without engine dismantle from the car it is possible to execute a set of the main operations on repair.

Before the beginning of any works it is very desirable to wash out a motor compartment and the engine a water stream. To work with the pure engine it is easier, pollution of the internal device of the engine is prevented.

To expand working space and not to damage coloring, uncover a motor compartment and hinged mudguards.

If traces of leaks of oil or the cooling liquid, indicating need of replacement of laying are observed, all works as a rule are carried out without engine dismantle. Without dismantle it is possible to replace laying of the oil pallet, a head of the block of cylinders, laying of inlet and final collectors, forward and back covers, an epiploon of a cranked shaft.

Without dismantle of the engine it is also possible to remove such hinged units as the pump of cooling liquid, a starter, the generator, the distributor of ignition, inlet and final collectors, and also the fuel pump and the carburetor.

As the head of the block of cylinders too can be removed without engine dismantle, repair of the klapanny mechanism is possible also.

Without dismantle it is possible to perform also such works as replacement or check of a condition of a gear belt, gear wheels of a drive of a cam-shaft, the oil pump, consolidation of a forward cover.

In extreme cases when there is no necessary equipment, without removal of the engine it is possible to replace piston rings, pistons, rods and shatunny loose leaves, отхоннинговать cylinders. However, to perform these works without removal of the engine it is not recommended, as cleaning of accompanying details and preparatory activities are required.

In the corresponding heads of this management actions for dismantle, check and installation specified above units are in detail described.
