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 capital or general repairs, some preparatory steps have to be taken.

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

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

The necessary requirement is existence of the winch or the And-shaped frame. Make sure that the acquired or hired equipment conforms 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 this work is the safety of its performance reached due to 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 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 makes work by forces of one person almost impossible.

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

Be ready to refusal of use of the car for the period of carrying out capital repairs of the engine. For implementation of some procedures it is necessary to use services of automobile repair shop (it is about procedures which implementation demands use of the special and machine equipment). Such workshops usually have very busy schedule of loading therefore it is necessary to take care beforehand of the arrangement on performance of the required repair.

At extraction and installation of the engine always observe extreme care. The neglect this requirement is fraught with receiving serious injuries and mutilations. Preliminary planning, preparation and care of implementation of all procedures are the key to a successful completion of work.
