KAMAZ engine has many complex parts and assemblies. But the most complex unit is such a spare part as a high-pressure fuel pump. KAMAZ is necessarily equipped with this pump. At the same time, it does not matter what modification and load capacity it has - the pump is on all models without exception. This unit is distinguished 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. KAMAZ injection pump (high pressure fuel pump), although it has high reliability, sooner or later every detail needs to be replaced and repaired. In this article, we will consider cases in which replacement of this unit is required, and also learn how it functions.

Injection pump device (KAMAZ) and its replacement

Replacing thisspare parts is a complex technical process that requires certain knowledge, skills and efforts. Not in the last place here is the availability of special equipment, without which the replacement or adjustment of the KAMAZ high-pressure fuel pump is simply impossible. It is also worth noting that the KAMAZ high-pressure pump plays a crucial role in the supply of diesel fuel through the fuel line. If it does not work, the engine will also stall, and it will simply be impossible to start the car. And contribute to the breakdown of contaminated nozzles, accidental ingress of dust and other small particles. But water is the main enemy for KAMAZ injection pump. When this liquid enters the pump device, all its work immediately stops, and repair is no longer enough. The only thing that can save the situation is a complete replacement of the pump, and it is also carried out at 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 the diagnosis of fuel lines, as well as to clean or replace the injectors in a timely manner. In case of severe contamination (as a rule, this is detected after diagnostics), it is imperative to clean the entire fuel system, otherwise the breakdown of the KAMAZ high-pressure fuel pump is inevitable.

How can I find out if the pump is faulty?

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 much the pump has left to "live" and whether it is time to send it for diagnostics. So, let's look at the main signs that indicate the incorrect operation of this unit:

1. The first thing 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 you turn the ignition key, it means that it is time to go for diagnostics.
3. Fuel consumption. This, of course, is a whole story - many drivers often scold even a serviceable KAMAZ for such a high consumption (about 40 liters of diesel fuel with a load of 15 tons), but if the mark goes even higher, know that the problem is in the pump.
4. And the last sign is black smoke from the exhaust.

Knowing these signs, you will always know when to seek help from specialists and, if necessary, repair the fuel system.
