In the process of adjusting the valve clearance of the mechanical tappet, selecting a quiet place, avoiding wind and reducing dust, opening a valve chamber cover, after opening the cover, taking 8 valves close to the direction of a vehicle head as exhaust valves, taking 8 valves close to a cab as intake valves, speaking the gear to be hung on a 5 gear, jacking a front wheel on one side by using a jack, remembering a tightening hand brake, turning a manual tire, turning the bulge of a camshaft to the right top, and measuring the valve clearance by using a feeler gauge when the camshaft is turned to the position right above. And then continuously turning the wheels, respectively measuring the data of 16 valves, accurately recording the data, and determining an error allowable range according to official engine parameters, wherein the valve with the error exceeding the range is the valve clearance to be adjusted. Then, the valve gasket needing to be adjusted is taken out from the cam shaft and the tappet, the frequently used tool is a large-small straight screwdriver, the small screwdriver needs to grind the knife edge as thin as possible, firstly, the notch of the valve tappet barrel is rotated to the position between the two cam shafts, the large screwdriver props against the edge of the valve tappet barrel and presses the tappet barrel downwards with force, the very large force is needed to resist the valve spring, the small screwdriver is used for assisting the large screwdriver to press downwards, the force is applied between the gasket and the tappet barrel to jack the gasket up and tilt the gasket upwards, and when the gasket is seen to be separated from the tappet barrel, the force application direction of the large screwdriver is slightly transverse and drives the gasket outwards. When the pad is half out, the pad is protected by gloves and the like, and then the pad is ejected out from the other side. The original data on the pad is visible after the pad is wiped clean. Calculating to obtain the thickness of the new gasket, and then putting the new gasket in. It follows from the above process that a large amount of effort is consumed against the valve spring during the process of removing a gasket and placing a new gasket.
