If your iron friend recently went through a major overhaul “heart” (i.e. motor) in the near future you need to take care of careful operation, without jerks and races. What does it do? The answer to this question you will learn in this article.running the engine after overhaul

Why do we need this process?

Running the engine after overhaul – the procedure is mandatory, without which it can not do any motor that have recently undergone serious structural changes. The reason is the following: new parts that have been installed to replace worn-out, must pass the stage of grinding, after which the level of friction between the sleeve and the rings will be back in place.

As a rule, after boring and grinding of new parts repaired motor must have 2 thousand kilometers in a sparing mode. Many motorists believe that after 2 thousand running the engine after the overhaul is completed and it can be used fully. It is fundamentally wrong, because during this period of time, the new parts only lapped each other, and finally they  are adapted only after 15 thousand kilometers. Only then can you squeeze out all the juices. If sooner, all new items will be heavily damaged, and then you have to go back to STO, when ordering those same services have familiar mechanics. Repair of engines, as a rule, is not cheap, and a buy a used motor will not save you from significant expenses.repair of engines UAZ

Experts say, the load on the refurbished unit should not exceed the level more than 60 percent of its total capabilities. It provides smooth shifting, slow acceleration and braking, no excessive speed. It was then running the engine after overhaul will give you a new, powerful and reliable motor that will provide the car a harmonious and smooth running.

Need quality parts in this procedure?

Of Course, Yes! Every detail, even the highest quality needs to be tested. And no matter what cars is the engines - "UAZ", "VAZ" or “BMW” (the result is the same). And if one of the mechanics says the opposite, this indicates a low level of qualification as a specialist (or the desire to “cut” more money from the client).
