KAMAZ-740 fuel system: structure and principle of operation


Dimensions

What is necessary for high-quality installation of a tank on KamAZ? Full compliance with dimensions. Before you purchase it, you need to make sure it is fully compatible with a specific KamAZ truck model. One of the most important indicators of dimensions is the length of the tank. The KamAZ plant and its subsidiaries adhere to the following values ​​for this parameter (in mm):

  • 710;
  • 750;
  • 950;
  • 1200;
  • 1360;

As for the cross-sectional dimensions, they range from 400×490 to 660×660 mm. But, again, these indicators are characteristic of the main manufacturer, while others may have almost any modification. To date, the maximum length does not exceed 1920 mm.

Volumes

For the simplest tasks, without having to travel a long way without stopping to refuel, a standard 125 liter fuel tank is used. This is the smallest volume possible. But due to the high level of fuel consumption and to increase the amount of reserves, larger options are used. The manufacturer provides the following liter variations:

  • 125;
  • 170;
  • 210;
  • 250;
  • 300;
  • 350;
  • 400;
  • 450;
  • 500;
  • 600.

In addition to standard modifications, there are many others with non-standard volumes. The largest capacity can reach 700 liters. This is explained by the fact that the fuel tank is produced not only at KamAZ plants. In fact, among the offers there are more products from other enterprises. But in order to produce such high-tech products, compliance with all necessary GOST standards is required. If this is the case, then the fuel tank will last a very long time, regardless of the manufacturer.

The procedure for adjusting the injection pump

The adjustment process is accompanied by the following actions:

  • washing the structure with special compounds;
  • checking the low pressure valve. It should be unscrewed when closed, the upper section is upholstered for settling. As a result, the bypass hole should close;
  • assessment of the correct operation of injection advance;
  • adjust the cyclic feed by unscrewing or tightening;
  • idle adjustment - normally it gives 770 rpm;
  • checking the hydraulic corrector is done by turning it in any direction.

The installation of fuel injection pumps should be entrusted to specialists - this requires experience and the availability of equipment. Otherwise, there is a risk of unpleasant consequences - from a fuel leak to a major engine overhaul.

Rules of care

The fuel tank of a KamAZ truck is unpretentious and requires only some preventive measures. What should be done to extend the service life?

  1. Replace filters in a timely manner.
  2. Reliable installation.
  3. Make sure there are no scratches and the condition of the paint.
