General information
Originators of the real Management do not recommend to owners of cars to undertake performance of major maintenance of RKPP independently. During performance of procedures of dismantling and assembly of a transmission it is necessary to remove, and then to establish into place a set of small components. It is necessary to make mass of the most exact measurements and, by selection of adjusting washers, rings and remote plugs, accurately to expose a set of gaps. In view of all aforesaid, it will be more reasonable to charge performance of major maintenance of RKPP to specialists of car-care center. Let's notice that in many cases there is a possibility on an exchange basis to get the restored block that often there is cheaper, than a carrying out difficult repair.
Despite the told, independent performance of repair of RKPP by the amateur mechanic at all is not absolutely impossible action. Indispensable conditions are only existence of the necessary special tool and accuracy in an approach to performance of all procedures.
The number necessary for performance of regenerative repair of RKPP of tools includes nippers for removal of internal and external lock rings, a stripper of bearings, a hammer with sliding brisk, a set of drifts and center punches, a tsiferblatny measuring instrument of DTI and, probably, a hydraulic press. Besides, certainly, the workbench, or the special assembly stand is required strong, equipped with a vice.
During performance of procedures of dismantling of RKPP try to remember, and it is better to write down, an order of installation of each of removed details.
Before starting transmission dismantling, it will be reasonable to try to analyse symptoms of its refusals for the purpose of approximate definition of their reasons. Many refusals are unequivocally connected with failure of quite certain components. See also Section devoted to diagnostics of malfunctions of RKPP, at the beginning of the Management.
Let's consider in more detail three of applied on cars of a box of gear shifting considered in the real Management: F5М31 (Galant), F5М21 (Mirage of 1.5 l) and F5М22 (Mirage of 1.8 l).
