Who knows how to adjust the valve of 12V 190 diesel engine according to the crankshaft angle?

It can be adjusted according to the ignition sequence, and the disc turns 0 degrees. When both tappets of a cylinder can rotate, it is the top dead center of the compression stroke of the cylinder, and then the exhaust valve of the cylinder can be adjusted. Then, according to the ignition sequence, adjust one cylinder at 60 degrees for each plate. The intake valve clearance of non-hydraulic tappets is 0.40mm, the exhaust valve clearance is 0.45 mm, and there is no clearance for hydraulic tappets. 12V 190 The general ignition sequence is 1, 8, 5, 10, 3, 7, 6,1,2, 9, 4,1. I hope I can help you!
