How to adjust the valve of BYD F3473 machine

When adjusting, first loosen the lock nut and adjusting screw, insert the feeler gauge with the same thickness as the specified value of the valve clearance into the gap between the adjusted valve foot and the rocker arm, rotate the adjustment screw, and pull the feeler gauge back and forth, when you feel that the feeler gauge has slight resistance, you need to recheck after tightening the lock nut, and if the gap changes, you need to re-adjust.

There are two main ways to adjust the valve clearance:

1) Cylinder-by-cylinder adjustment method: The cylinder-by-cylinder adjustment method only requires that each cylinder to be adjusted be shaken to the top dead center of the cylinder's compression stroke (at this time, the intake and exhaust valves are completely closed) to adjust the cylinder valve clearance. This method requires finding the top dead center of the compression stroke of each cylinder and memorizing the work sequence of the engines of various models (ignition sequence for gasoline engines and fuel injection sequence for diesel engines).

2) Two adjustment method: The two adjustment method is to adjust all the valves on the engine in two times, this method is simple to operate and has high work efficiency. No matter how many cylinders you have, you only need to adjust them twice.

OneUse a wrench to loosen the BYD F3 valve adjustment screw.

2. Use a screwdriver to twist the BYD F3 valve screw shaft.

3. Use your fingers to lift the BYD F3 valve screw shaft upwards.

4. After determining the position, use a wrench to tighten the BYD F3 adjustment screw.

Note: Although there are many types of vehicles, the structure is similar. This should be said to be the credit of standardization, but also the need for large-scale production lines. With the development of society, the progress of science and technology and the change of demand, the shape of railway vehicles has begun to change, especially the passenger car is no longer the same old face.

However, their basic structure has not changed significantly, but the specific parts have a more scientific and advanced structural design.

Generally speaking, the basic structure of the vehicle is composed of five parts: the car body, the undercarriage, the running part, the coupler buffer device and the braking device.

The body is the part of the vehicle that is used to load goods or passengers, and is the basis for the installation and connection of other components of the vehicle. The body of the early vehicles was mainly made of wood, supplemented by steel plates, bow rods, etc. In modern times, the car body is mainly steel structure or light metal structure.

The valve must know the ignition sequence, such as 1-3-4-2 of 4 cylinders, first turn 1 cylinder to the compression top dead center to adjust the near exhaust valve of 1 cylinder, then rotate the crankshaft 180 degrees according to the working direction of the engine, turn the 3 cylinders to the compression top dead center to adjust the near exhaust valve of the 3 cylinders, turn 180 degrees again, turn the 4 cylinders to the compression top dead center to adjust the near row top dead center of the 4 cylinders, and adjust the 2 cylinders, each turn of the 6 cylinders is 120 degrees, and the 8 cylinders are 90 degrees each time. However, the 8-cylinder one generally does not need to be adjusted. In addition, you can also use the "double, row, no, in" method.

Such as 4 cylinders: 1-3-4-2

For the first time, the top dead center of the 1-cylinder compression double row does not enter.

The second 4-cylinder compression top dead center does not enter the double row.

Adjust the two fingers close to the exhaust valve, adjust the exhaust valve with the exhaust finger, do not adjust near the exhaust valve, and adjust the intake valve with the intake finger.
