Fig. 11.35. Details of a longeron and mudguard

In fig. 11.35 the details of a longeron and a mudguard delivered in spare parts are presented.

At repair of a front of a body the following works can be carried out:

1) replacement of a forward longeron, for what:

— open access to internal and external surfaces of a longeron;

Fig. 11.36. Preparation of an installation site of a new longeron and longeron for installation

— previously cut out a longeron, as shown in fig. 11.36;

— adjust the interfaced surfaces;

— fix a new longeron (the size A has to make 100 mm);

— the joint has to settle down on the site 250 mm (size B);

— adjust and insert a longeron on the place, fix it by the fixed pincers or take welding;

— check the control amount of installation of a longeron (see соотв. section);

Fig. 11.38. Way of installation of a longeron entirely

— at their coincidence weld a longeron (fig. 11.37, 11.38);

— execute where it is possible, contact spot welding;

— on other sites execute welding by electrorivets (MAG);

2) replacement of a part of a longeron (see fig. 11.37), for what:

— open access to the site of works;

— previously cut out the damaged section;

— drill or a soshlifuyta of a point of welding;

— remove a longeron;

— adjust the interfaced surfaces and apply welding primer;

— record a longeron in fastenings.

— weld a longeron electrorivets outside, execute where it is possible, contact spot welding;

— weld electrorivets from within;

3) replacement of an arch of a forward wheel (fig. 11.39), including the strengthening arch element, for what:

— cut out the replaced element;

— to a soshlifuyta or drill its connections with the interfaced details;

— smooth out surfaces of the interfaced details;

— apply welding primer;

— adjust and fix a wheel arch;

— weld a wheel arch;

4) replacement of a support of the engine, for what:

— drill and remove the replaced engine support;

— smooth out and align a support installation site;

— apply welding primer;

— fix an engine support by a clamp;

— check correctness of installation of an arm;

Fig. 11.40. Ways of fixing of a support of the engine

— weld an engine support (fig. 11.40);

5) replacement of the lower beam of a radiator, top beam of a radiator and trailer panels, for what:

— cut out the deleted elements, having receded 10 — 15 mm from connection with the interfaced details;

— drill and remove their remains;

— to a welding point soshlifuyta;

— remove the remains of the deleted details;

— grind to naked metal;

— apply welding primer.

— fix the established details;

— check correctness of their installation;
