1.1.3. Working conditions and tools

For carrying out repair work the pure, well shined workplace which is equipped with a workbench and a vice is necessary. There should be enough place to spread out details and to arrange them so that not to clean constantly. Work in well equipped room it gives pleasure, the car can be disassembled and built again. Unfortunately, not everyone has such ideal workplace and consequently is compelled to improvise. Compensation of this shortcoming needs more time and accuracies.

The necessary component at repair is a complete set of the high-quality tool. Quality here the major requirement as the cheap tool can become very expensive because it comes off and destroys thus expensive details. The good high-quality tool can be used long time and compensates finally costs of its acquisition. The basis of a tool kit is made by a set of wrenches which it is possible to establish on any well available place. A set of cap keys - excellent addition to the previous set, especially in case of sitting tight bolts and nuts or at a lack of a place. For reduction of expenses it is possible to use also a set of the combined keys on which one end there is a usual rozhkovy key, and on other a cap key of the same size. In drawing it is shown below, how these keys look.

Appearance usual (above) and the combined keys (below).

Also the set of face heads is required. With their help it is possible to weaken bolts and nuts with deep landing. The following necessary item is a set of krestovy screw-drivers, nippers and a hammer. In addition to a base set it is possible to add some special tools which in most cases render the invaluable help, especially if certain works are required to be made quite often. It saves a large number of time. As an example it is possible to mention a shock screw-driver without which weakening of industrially tightened krestovy bolts hardly is possible, without having damaged them. Certainly it can be used for an inhaling of tight connections. Nippers are also often necessary for lock rings by which transmission gear wheels are fixed, shaft and similar details, and with a usual screw-driver to remove lock rings quite difficult. There are two types of nippers for the lock rings, one for external rings, others for the internal. They have straight lines or the bent captures. One of the most useful tools is the dinamometrichesky key, one of types of keys which can be adjusted so that it will be freely turned at achievement of a certain moment of an inhaling. There are similar keys with the strelochny indicator which points to the reached moment of an inhaling. The moments of an inhaling are specified in any modern repair manual so difficult groups of elements, for example, a head of cylinders can be tightened without damage threat owing to a peretyazhka.

The car model is more modern, the bigger number of tools is required for car maintenance in a condition ready for operation. Unfortunately, some specific works cannot be made without use of the special equipment, and which can strongly undermine your budget if not to charge them to experts. There are also simple works which too it is best of all to charge to experts. In spite of the fact that the universal measuring device renders significant assistance, in inept hands he can lead to large damages of electric equipment.

Though in this management it is shown, how it is possible to perform various works without the special tool (when its use is not obligatory), nevertheless it is better to work with the special tool. Especially it is necessary to do it, if the car has big run. It is possible to remove and establish various details also improvised methods and tools without danger of their damage. However use of the special tool ordered by firm in any case will save a lot of time and nerves.
