How to adjust the valve of Isuzu truck 10 cylinder

Without knowing the ignition sequence, there are two methods: 1: in-line four-stroke cylinder, which divides the number of cylinders into two and takes the middle as the symmetry axis to make the number of cylinders on both sides equal. Two people cooperate, and one person turns the crankshaft. When checking and adjusting the valve clearance of a cylinder on the right side of the symmetry axis, just pay attention to the intake valve of the corresponding cylinder on the left side of the symmetry axis. When the valve moves slightly, the valve clearance of the right cylinder can be checked and adjusted. 2: When the 1 valve in a cylinder is in the maximum open position (the side valve train can be observed from the valve cover, that is, when the cam tip faces the plunger; The overhead valve mechanism can observe the valve rocker arm, and when its end opens the lowest position of the valve downwards, it can check and adjust the clearance of the other valve of the cylinder. According to this, all valve clearances of cylinder engines can be adjusted one by one. When you know the ignition sequence, you can use the twice adjustment method.
