How to adjust the valve of 18 k tractor

Valve adjustment must know the working sequence. For example, cylinder 4, 1-2-4-3, first turn cylinder 1 to the intake and exhaust valves of cylinder 1, then turn the crankshaft to 180 degrees according to the working direction of the engine, turn cylinder 3 to the intake and exhaust valves of cylinder 3 to the compression top dead center, and then turn cylinder 4 to +080 degrees.

In addition, you can also use the method of "double, row, no, advance". For example, cylinder 4: 1-2-4-3

1 2 4 3

The top dead center of 1 cylinder is compressed for the first time, and the exhaust valve is adjusted with two fingers instead of two fingers.

For the second 4-cylinder compression, the top dead center does not enter the double row, the intake and exhaust valves are not adjusted, and the intake valves are adjusted.
