If your iron friend has recently experienced a major overhaul of the "heart" (that is, the motor), then in the near future you need to take care of its careful operation, without jerks and jumps. What is it for? You will learn the answer to this question in this article.
Why is this process necessary?
Running in an engine after a major overhaul is a mandatory procedure, without which not a single engine can do, which has recently undergone major structural changes. The reason is this: new parts that were installed to replace worn parts must go through a lapping stage, after which the level of friction between the sleeve and the rings will return to its place.
As a rule, after boring and grinding new parts, the repaired motor must go 2 thousand kilometers in a gentle mode. Many motorists believe that after 2 thousand, the engine run-in after overhaul is completed and it can be operated to its fullest. This is fundamentally wrong, because during this period of time new parts only rub against each other, and finally they adapt only after 15 thousandkilometers. Only after that you can squeeze all the juices out of the machine. If this happens earlier, all new parts will be badly damaged, and then you will have to go to the service station again, ordering the same services from a familiar mechanic. Engine repairs tend to be expensive, and buying a used engine won't save you a lot of money.
As experts say, the load on the repaired unit should not exceed more than 60 percent of its total capacity. This provides for smooth gear shifting, slow acceleration and braking, and the absence of increased revs. It is then that the engine break-in after the overhaul will give you a new, powerful and reliable engine that will provide the car with a smooth and smooth ride.
Do quality parts need this procedure?
Of course, yes! Any detail, even of the highest quality, needs to be run-in. Moreover, it does not matter on which machines the engines are being repaired - UAZ, VAZ or BMW (the result is the same). And if one of the mechanics claims otherwise, this indicates a low level of his qualifications as a specialist (or a desire to “cut down” more money from the client).
How effective is this procedure?
After running-in, a refurbished internal combustion engine will fully display its inherent characteristics, namely:
- Will run steadily at idle (frequency does not exceed 600 rpm).
- When shifting gears fromlow to high or vice versa, as well as when the gearbox is in neutral, the car does not stall and does not make unusual sounds.
- The rotation of the crankshaft (using the handle) is made without any additional effort.
The car will acquire such properties, of course, not immediately, but be sure - after 2 months of operation in the city and beyond, running the engine after overhaul will allow it to be operated in full.
