THE GENERAL DATA

If the decision on dismantle of the engine for major repairs carrying out, or repair of the basic knots it is necessary to spend certain preparatory measures was accepted.

Will plan extremely important a place in which to be made works. Undoubtedly, 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 and pure concrete or asphalted platform is required at least.

Washing of a motor compartment and the power unit before the dismantle beginning will allow to keep the tool clean and a constant working condition.

Also will be necessary the floor lift or тельфер. Be convinced that these devices have a stock on load-carrying capacity and are capable to lift the engine with transmission. Observance of security measures here plays a paramount role, as lifting of the engine from the car – operation potentially dangerous.

If works on engine dismantle are spent by not skilled person the assistant is necessary. Consult and ask to help the persons having experience in such works. There is a set of examples of that as attempts alone to execute dismantle of the engine with lifting of last of a motor compartment came to an end unsuccessfully.

In advance plan the actions. Before beginning works hire or get all necessary tools and the equipment. To some adaptations providing safety at dismantle and installation of the engine, and also decrease in expenditures of labour concern (besides the lift) a jack-cart of the sufficient load-carrying capacity, a full set of keys and оправок, wooden Pads, rags and solvent for cleaning of inevitable pools from the spilt working liquids of the engine. If the lift is hired, about it agree in advance, having performed all works in which this mechanism is not required. It will allow to save money and time.

Keep in mind that considerable time you cannot take advantage of 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 centre workshop. These enterprises work under the schedule and expedient will consult there before engine dismantle precisely to estimate expenses of time for repair and restoration of details.

Always at dismantle and installation of the power unit 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.
