Capital repairs - the general information
Capital repairs of RKPP demand from the performer of high skill level as it assumes performance of exact exposure of a set of gaps, by selection of adjusting washers and remote plugs. Besides, it is rather difficult to find internal components of the transmission on free sale, not to mention the high prices of them. In view of everything told, authors of the present manual recommend in case of problems in functioning of RKPP to make replacement it on the new or restored block.
Nevertheless, rather skilled amateur mechanic without effort can execute repair of the transmission by own forces on condition of existence of the special tool. Remember that all procedures have to be performed strictly as appropriate. You do not hurry, fuss, try to pass any trifles.
In number of special tools without which use repair of RKPP becomes impossible nippers for extraction of external and internal lock rings, a set of strippers, the hammer with sliding brisk, a set of drifts, the dial measuring instrument of plunger type and, whenever possible, hydraulic press belong. Besides, the workplace has to be equipped with a big strong workbench with a vice.
In the course of dismantling of the transmission it is necessary to fix carefully on paper the adjusting provision of all removed components for the purpose of a guarantee of correctness of placement them at assembly.
Before starting dismantling of RKPP it is necessary to try to define for itself the possible reasons of the violations taking place. Some problems are rather accurately tied to concrete knots of the transmission that allows to reduce significantly time for identification and elimination of defects.
