The valve adjustment method is: 1. Preheat the engine until the cooling water temperature reaches 80℃-90℃, open the timing mark inspection holes on the clutch housing and cylinder head cover, and confirm that the cylinder head bolts are tightened to the specified torque. 2. Turn the crankshaft so that the "0" engraved line on the flywheel is aligned with the marking line on the clutch housing, and confirm that the cambered surface of the rocker arm of the intake and exhaust valve of the first cylinder is in contact with the base circle of the camshaft cam, that is, the piston of the first cylinder is at the compression top dead center (if the rocker arm is in contact with the cam, the crankshaft should rotate 360), and the valve is in the closed position. 3. Loosen the lock nut 2 of the adjusting screw 1 and turn the adjusting screw with a screwdriver to make the gap a between the lower end face of the screw and the upper end face of the valve stem 3 reach the specified value (determined by the thickness of the thickness gauge). Keep the screwdriver still, tighten the lock nut to the specified torque, and then insert the thickness gauge into the gap A for re-inspection, so that the gap between the intake valve and the exhaust valve of the first cylinder can be adjusted.
