Methods of removal of the engine and necessary precautionary measures

If the analysis of a situation showed need of removal of the engine for carrying out its major or general maintenance, some preparatory steps should be undertaken.

Existence of a suitable workplace is an important condition of successful performance of repair in the highest measure. The convenient working platform with a place for car parking is required. If using a garage room or a room of a workshop of car-care center is impossible, a necessary condition is existence at least a flat horizontal platform with a firm covering (it is desirable asphalt or concrete).

Careful cleaning of an impellent compartment and the engine before extraction it from the car will allow to keep the tool during procedure performance clean and an order that considerably helps the correct organization of works.

The necessary requirement is existence of the winch or And-shaped..... Make sure that the acquired or hired equipment corresponds according to the load-lifting characteristics to the requirement for keeping of total weight of the engine with all hinged units. The main condition during carrying out this work is the safety of its performance reached at the expense of observance of the appropriate measures of safety.

If independent extraction of the engine is made by the amateur mechanic for the first time, presence of the assistant is desirable. Useful there will be also timely council of more skilled expert. During posting of the engine there is a set of the moments when need of simultaneous performance of several operations does work by strengths of one person almost impossible.

Carefully plan in advance all course of the forthcoming works. Take care of preliminary acquisition or rent of the necessary special equipment and the tool. (Except the elevating equipment) it is possible to carry to number of the adaptations doing procedures on extraction of the engine and its installation into place safer and convenient also such, as the powerful floor (telezhechny) jack, a complete set of wrenches and replaceable heads (see. The tool), wooden blocks, and also rags and solvent enough for collecting the spilled oils, fuel and a cooler and destruction of their traces. If the load-lifting equipment is planned to hire, it is necessary to take care of it the day before and beforehand to make all preparatory procedures and procedures which can be executed before connection of an elevating rigging. Such approach will allow to save time and means.

Be ready to refusal of using the car for the period of carrying out major maintenance of the engine. For performance of some procedures it is necessary to use automobile repair shop services (it is a question of the procedures which performance demands use of the special and stanochny equipment). Such workshops usually have very busy schedule of loading therefore it is necessary to take care beforehand of the arrangement on performance of demanded repair.

At extraction and engine installation always observe extreme care. The neglect this requirement is fraught with receiving serious traumas and mutilations. Preliminary planning, preparation and care of performance of all procedures are pledge of a successful conclusion of work.
