Methods of removal of the engine and necessary safety measures

If the situation analysis has shown necessity of removal of the engine for carrying out of its capital or general repair, some preparatory steps should be undertaken.

Presence of a suitable workplace is the important condition of successful performance of repair in the higher measure. The convenient working platform with a place for car parking Is required. If using a garage premise or a premise of a workshop of car-care centre is impossible, a necessary condition is presence 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 its extraction from the car will allow to keep the tool during procedure performance clean and an order that appreciably helps the correct organisation of works.

The necessary requirement is presence лебедки or the A-shaped frame. Make sure that the got or hired equipment corresponds under the load-lifting characteristics to the requirement on keeping of total weight of the engine with all hinged units. The basic condition during carrying out of the given work is the safety of its performance reached at the expense of observance of corresponding security measures.

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

Carefully plan all course of 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 more safe and convenient also such, as powerful floor (тележечный) a jack, the complete set of wrenches and replaceable heads (the Tool see), wooden blocks, and also enough of rags and solvent for gathering of the spilt 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 of major repairs of the engine. For performance of some procedures it is necessary to take advantage of automobile repair shop services (it is a question of the procedures which performance demands application special and станочного the equipment). Such workshops usually have very much a loading busy schedule, 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 reception of serious traumas and mutilations. Preliminary planning, preparation and carefulness of performance of all procedures are pledge of successful end of work.
