Preparatory actions and the list of repair procedures which can be executed without engine extraction from the car

Make cleaning of an impellent compartment and external surfaces of the power unit with application of one of a wide range of special solvents. Such processing will allow to avoid dirt hit in the engine.

In case of need, the forthcoming work defined by character, it is possible to remove a cowl for the purpose of ensuring freedom of access to components subject to service (see. Head Body). Cover car wings with special covers, or simply old blankets in order to avoid casual damage of a paint and varnish covering.

If existence of suspicions on losses of depression or the leakage of oil cooling liquids, the fulfilled gases, etc. indicates need of performance of replacement of the corresponding laying or epiploons, practically any of the listed procedures can be executed without engine extraction from the car (in situ). Told concerns procedures of replacement of laying of the inlet pipeline and final collectors, the pallet of a case, heads of cylinders, and also both epiploons of a cranked shaft.

Dismantle, repair and installation of such external knots and hinged units as the inlet pipeline, final collectors, the case pallet, oil and water pumps, a starter, the generator, the distributor of ignition and power supply system components also can be made by in situ.

As heads of cylinders can be removed from the engine without preliminary extraction of the power unit, service of the klapanny mechanism also can be made directly on the car. Besides, in situ is usually carried out replacement of camshafts, a gas-distributing belt and cogwheels of a drive of GRM.

In an emergency without dismantle of the power unit performance of repair and replacement of piston rings, pistons, rods and shatunny bearings of a cranked shaft is allowed also. However it is not necessary to abuse such possibility in view of the difficulties connected with need of observance of purity and carrying out a number of preparatory procedures.
