Replacement of injection pump (KAMAZ) - causes of failures and properties of the fuel pump of high pressure

KAMAZ engine has many complex parts and components. But the most complicated unit is a spare part, like a fuel pump. KAMAZ must be manned by this pump. At the same time, it does not matter what kind of modification and load capacity it has - the pump is on all models without exception. This unit is characterized by its complex design and functionality. It is simply indispensable in the fuel supply system, so you should not repair it yourself, it is better to entrust this work to professionals. The injection pump of KAMAZ ( high-pressure fuel pump ), although it has high reliability, but sooner or later, every detail requires replacement and repair. In this article, we will consider the cases in which the replacement of this unit is required, and also we will learn how it functions.

The device for injection pump (KAMAZ) and its replacement

Replacing this part is a complex technical process that requires certain knowledge, skills and efforts. Not the last place here and the availability of special equipment, without which the replacement or adjustment of the injection pump KAMAZ is simply impossible. It is also worth noting that KAMAZ's high-pressure pump plays an important role in supplying diesel fuel via the fuel line. If it does not work, the engine will die, and it will simply not be possible to start the car. A contributing to the breakage of contaminated jets, accidental ingress of dust and other small particles. But water is the main enemy for the KAMAZ injection pump. If this liquid gets into the pump device, all its work immediately stops, and repair here is indispensable. The only thing that can save the situation is a complete replacement of the pump, and it is also carried out on a specialized service station.

How can I extend the life of the fuel system?

In order for the pump to last as long as possible, it is enough just not to save on diagnostics of fuel lines, and also to make timely cleaning or replacement of injectors. In case of severe pollution (as a rule, this is detected after diagnosis), it is absolutely necessary to clean the entire fuel system, otherwise the failure of the KAMAZ injection pump is inevitable.

How can I find out about pump failure?

Of course, the injection pump itself will not tell you about a breakdown, so you need to be guided by certain rules, by which you can understand how long it took to "live" the pump and whether it's time to send it for diagnostics. So, let's look at the main signs that indicate the wrong operation of this unit:

1. The first thing that drivers notice is a significant reduction in engine power. KAMAZ is already weak, especially when it is overloaded, but when it becomes generally "frail," this is the very "bell" that indicates a malfunction of the fuel system.
2. Starting the engine with problems. If the engine does not want to work when turning the ignition key, it means it's time to go to the diagnosis.
3. Fuel consumption. This, of course, is a whole story - many drivers often scold even a good KAMAZ for such a large expense (about 40 liters of diesel fuel at a load of 15 tons), but if the mark went even higher, know that the problem is in the pump.
4. And the last sign is black smoke from the exhaust pipe.

Knowing these signs, you will always be aware of when you need to seek help from specialists and, if necessary, make repairs to the fuel system.
