GENERAL INFORMATION

If the decision on engine dismantle for carrying out major maintenance, or repair of the main knots was made, it is necessary to hold certain preparatory events.

It is extremely important to plan 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 the demontazhy 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 units. Observance of security measures plays a paramount role, as engine lifting from the car – operation dangerous.

If works on dismantle of the engine are carried out by the inexperienced person, the assistant is necessary. Consult and ask to help the persons having experience in such works. There are many types of works when lifting engine from a motor compartment which exclude their performance by one person.

In advance plan the actions. Agree or get all necessary tools and the equipment before beginning works. To some adaptations providing safety at dismantle 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 liquids. If the lift is hired, agree in advance, having performed all works in which this mechanism is not necessary. 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 in a car-care center workshop. These enterprises work according to the schedule and expedient will consult there before engine dismantle precisely to estimate costs of time of repair and restoration of details.

Always at dismantle of the engine be very attentive. Rash actions can cause serious traumas. In advance consider the actions. Do not feel sorry on it for time, for the main thing – work without traumas.
