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

If the decision on removal of the engine was made, then before it hold preparatory activities.
It is extremely important to define the 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 the place for storage of the car. If there is neither workshop, nor a garage, then the flat smooth concrete or asphalt platform will be required.
Washing of a motor compartment and the engine before removal will allow to keep the tool clean and the constant working condition.
Also will be necessary the elevator or a telfer. Make sure 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 raising of the engine from the car – potentially dangerous operation.
If works on removal of the engine are carried out by the inexperienced person, then 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 raising of the engine from a motor compartment which exclude their performance alone.
In advance plan the actions. Podgotovte all necessary tools and the equipment before beginning works. To some devices ensuring safety at removal and installation of the engine, and also decrease in labor costs strong supports, a full set of keys and mandrels, wooden blocks, rags and solvent for cleaning of inevitable pools from the spilled operational liquids belong (besides the elevator). If you hire the elevator, then agree about it in advance and perform all works during which this mechanism will not be required. It will allow to save money and time.
Keep in mind that considerable time you will not be able to use the car. For performance of some works inaccessible in house conditions (due to the lack of the special equipment), it is necessary to address services of service station or a specialized workshop. These enterprises work according to the plan therefore it will be expedient to consult before removal of the engine there precisely to estimate expenses of time for repair and restoration of details.
