The power unit consists of the engine, coupling and a transmission. Remove it by means of the hydrolift or тали, 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 precautions
If the decision on removal of the engine for carrying out of major repairs is accepted or
Repair of the basic knots it is necessary to spend certain preparatory measures.
It is the extremely important to define a place where works will be performed. Undoubtedly, 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 тельфер. Be convinced that these devices have a stock on load-carrying capacity and are capable to lift the engine with all hinged units. Observance of security measures plays a paramount role, as lifting of the engine from the car – potentially dangerous operation.
If works on engine removal are spent by not skilled person the assistant is necessary. Consult and ask the help at those who has experience of performance of such works. There are many modes of work on lifting of the engine 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 expenditures of labour, concern (besides the lift) the strong supports, a full set of keys and оправок, wooden колодки, rags and solvent for cleaning of inevitable pools from the spilt operational liquids. If it is supposed to hire the lift agree about it in advance and will 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 servicing deport or a specialised workshop. These enterprises work according to plan, therefore it is expedient to consult there before engine removal precisely to estimate expenses of time for repair and restoration of details.
At engine removal 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.
