The power unit consists of the engine, coupling and a transmission. Remove it by means of the hydrolift or a waist, lowering from an engine compartment on the cart. Thus tips of shaft of drives of forward wheels are disconnected from the power unit and remain on the car.
Removal of the power unit: methods and safety measures
If the decision on engine removal for carrying out major maintenance is made or
repair of the main knots, it is necessary to hold certain preparatory events.
It is extremely important to define a place where works will be performed. Undoubtedly, the best place for this purpose – a 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 is necessary. Consult and ask the help for those who has experience of performance of such works. There are many modes of work on engine lifting from a motor compartment which exclude their performance alone.
In advance plan the actions. Get 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 it is supposed to hire the lift, 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, probably, long 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 is 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 for the main thing is a work without traumas.
