In the process of machining, it is found that the initial position of the cylinder is wrong, so the cylinder should be adjusted.

1, the piston of the cylinder is placed at the compression end point, and then the intake and exhaust valves of the cylinder can be adjusted.

2. According to the principle of "three rows of two". That is to say, at this time, the intake valve of cylinder 2 and the exhaust valve of cylinder 3 must be completely closed, and the adjustment can also be checked.

3. For two cylinders with connecting rod diameters in the same plane, only one pair of valves can be adjusted at a time, so it is also possible to check and adjust the exhaust valves of five cylinders and the intake valves of four cylinders at this time.

4. Turn the flywheel 360 degrees, so that the six-cylinder piston is at the end of compression, and the remaining valves that have not been checked and adjusted will be completely closed. Therefore, turn the crankshaft twice to check and adjust all the valves of the engine.
