How to adjust Cummins 6-cylinder valve?

There are two ways to adjust Cummins 6-cylinder valve. One is cylinder-by-cylinder adjustment, and the valve clearance of each cylinder can be adjusted only by rotating it to the top dead center of its compression stroke. It is required to find the top dead center of the compression stroke of each cylinder and remember the power sequence of various engines. The second method is twice adjustment, in which all valves on the engine are adjusted twice. The method has simple operation and high efficiency. Automobile valve, also known as throttle, is responsible for injecting fuel into the engine and discharging exhaust gas. In traditional engines, each cylinder has only one intake valve and one exhaust valve. This design has the advantages of simple structure, low cost, convenient maintenance and good low speed performance. The disadvantage is that the power is difficult to improve, especially at high speed, the inflation efficiency is low and the performance is weak.
