The toothed gears are used in the power transmission systems. It is result from advantages of them (e.g. efficiency, reliability, fatigue life, high-load transmission). In the power transmission systems for trucks, and for cars with back drive, gear pairs are used. In that case it is possible to transfer turning moment under right angle. The most common in use in so-called main axle are bevel or hypoid gear pairs. Differential gears are mainly built basis of straight bevel gears. The paper presents method of preliminary determination of usability bevel gears for transfer turning moment. The method uses gears' models which are made with Rapid Prototyping techniques. The gears are placed in the testbed, which enables to steady load of gear pair. The observation of tooth contact makes possible to preliminary evaluate of correctness of gear pair's working. The tooth contact's changes are observed during gear rotation. The direct observation of tooth gears can be done using transparent material for gears. Besides, it is possible to determine temporary tooth contact and its changes in function of gears' rotation for existing metal gear pairs. In order to analyse, it is necessary to make copy of existing gears vacuum cleaning method. It uses the silicone forms as a template to make copies. It should be use transparent material. The method enables to analyse tooth contact in gear pairs after lifetime, thereby evaluating impact of working on correctness of gear pairs' working.
