2.2.5. General information and safety measures at removal of the power unit

If the decision on engine removal was made, before it hold preparatory events.
It is extremely important to define a place where works will be performed. Undoubtedly, the best place is the workshop. It is very important to have the equipped working platform, and also a place for car storage. If neither a workshop, nor the garage is not present, the equal smooth concrete or asphalt platform is required.
Washing of a motor compartment and the engine before removal will allow to keep the tool clean and a constant working condition.
Also will be necessary the lift or a telfer. Be convinced that these devices have a stock on loading capacity and are capable to lift the engine with all hinged units. Observance of security measures plays a paramount role, as engine lifting from the car – potentially dangerous operation.
If works on removal of the engine are carried out by the inexperienced person, the assistant will be necessary. Consult and ask to help persons who have experience of performance such works. There are many ways of performance of work on engine lifting from a motor compartment which exclude their performance alone.
In advance plan the actions. To Podgotovta all necessary tools and the equipment before beginning works. To some adaptations providing safety at removal and installation of the engine, and also decrease in labor costs belong (besides the lift) the strong supports, a full set of keys and opravka, wooden blocks, rags and solvent for cleaning of inevitable pools from the spilled operational liquids. If the lift will hire, agree about it in advance and perform all works at which this mechanism is not required. It will allow to save money and time.
Keep in mind that considerable time you cannot use the car. For performance of some works inaccessible in house conditions (in the absence of the special equipment), it is necessary to address to services of service station or a specialized workshop. These enterprises work according to the plan, therefore it will be expedient to consult there before engine removal precisely to estimate costs of time of repair and restoration of details.
At removal of the engine be always very attentive. Rash actions and haste can become the reason of serious traumas. In advance consider the actions. Do not feel sorry on it for time as the main thing is a work without traumas.
