11.20.3. Preparation and anticorrosive processing of the hidden cavities

In view of use of difficult processing equipment and need of high-quality performance of work processing of the hidden cavities is recommended to be carried out only at service stations of cars.
Order of performance of operations for protection against corrosion of the hidden cavities:
– install the car on the elevator, remove the details and an upholstery interfering access to the hidden cavities;
– wash out water with the temperature of 40-50 °C through technological and drainage openings the hidden cavities (tab. 11.2) and a bottom of a body to a pure effluence. At the same time lowering glasses of doors have to be lifted;
– remove the moisture which got to salon and a luggage carrier, blow compressed air all places of drawing anticorrosive structures;

Fig. 11.5. Hidden cavities of a body: 1 – cowl pockets; 2 – pockets of a forward door; 3 – pockets of a back door; 4 – cavities between arches of back wheels and back wings; 5 – back longerons of a floor; 6 – average cross-piece of a floor; 7 – forward cross-piece of a floor; 8 – thresholds of doors; 9 – forward longerons of a floor; 10 – cavities of amplifiers of a board of a front; 11 – cavities of amplifiers of a board of a front (from a motor compartment); 12 – cavities of connectors of thresholds of a floor; 13 – floor thresholds (from end faces); 14 – forward longerons; 15 – forward longerons of a floor (from below bodies); 16 – forward cross-piece of a floor (from below bodies); 17 – average cross-piece of a floor (from below bodies); 18 – back longerons of a floor (from below bodies); 19 – lower cross-piece of a back

– overtake the car in the camera of drawing anticorrosive structure and put on the elevator. Put with dispersion anticorrosive structure to the places shown in fig. 11.5;
– lower the car from the elevator, clear of pollution front surfaces of a body the rags moistened in white spirit.
