Repair and car operation

14.13.1. To repair or change?

THE GENERAL DATA

Speak, cars as people. The known share of justice in this comparison is. "Life" of generators, for example not very much differs from the human. One units work and reach mature age, others suffer from uncountable set of malfunctions. Some reliably serve some years, and then pulled hard "illnesses" lead up them to a stop. Duration of existence of others does not overstep the bounds of youth.

Despite it, большинтво generators it is possible to return to a life. Capitally repaired, restored, updated – name somehow – the generator – the phenomenon quite usual. There are two ways with which help he can be born"anew.

The first – when the old knot is cleared by streams of steam or simply washed out, and then painted outside and is on sale as restored, is frequent with "guarantee" of the replacement in most cases expressed by a phrase: "If it does not work, bring it back". Whether there is such generator out of operation in a month or later – it is not known.

The second way is to buy really restored unit. They differ high quality as were exposed to full dismantling, are cleaned, checked up, and the faulty and raising doubts of their part are replaced.

The generators restored industrially, pass in much similar process of restoration, and such small parts as brushes, contact rings and bearings are replaced without fail. The knot repaired at factory, is good, as new and at the same guarantees has the service life close to operation time of the new unit.

In the latter case generators are put on trial on the maximum loading and capacity. You receive that, for what pay. The recoloured generators usually considerably are cheaper, than qualitatively touched knots. You, of course, can get the repair complete set but if the case of your generator is faulty a choice at you does not remain.

By the way of generator replacement

The application and replacement tables which are let out by manufacturers, are usually exact, but some firms establish on the cars generators of various marks and the sizes. Even if old and new generators are at first sight identical, necessarily check up electric sockets, the maximum current of loading, adjusting arms, fastening of pulleys and distance from a plane of installation to a pulley – to be convinced that the generator pulley will be in one plane with pulleys on cranked to a shaft and the water pump.

Sometimes, in spite of the fact that the knot looks a little differently, its operation is possible. Despite "an origin" difference, generators have an identical maximum current of loading more often and are made so that all points of fastening and connection are in the same places.

Pulley, шпонка and a nut can not enter into the repair complete set. Then they are rearranged from old knot on the new.

It is necessary to find out also that has caused generator refusal. If the reason external the established spare parts can fail with the same success. Today it will be a question of most often meeting malfunctions of generators.

We repair

Besides unit replacement, there are other ways of the decision of problems about which it is told above. For example, many replace generators at bad contact of brushes though this malfunction it is possible to eliminate idle time зачисткой.

Way the first – to clear brushes independently and free of charge. Even if spare parts be required to you, this variant will appear the cheapest. It not such difficult to what it seems at first sight. If at you it will turn out nothing, in the worst, than earlier, position you will not appear.

The way of the second – to address for check and repair of the faulty generator to the expert. It is difficult to predict, in what repair cost will manage. It depends on character of the malfunction, necessary spare parts and their cost. In any case your expenses will make approximately half of cost of the unit restored industrially, but it is less than half of cost of the new generator – the economy will be considerable.

However in each of these situations it is necessary to take into consideration age of the generator, and also economic feasibility of replacement of one or two details (brushes or contact rings) if others shortly, possibly, fail. Replacement of details is more preferable to non-standard or expensive generators, but it makes sense to replace the most widespread models entirely.
