For the diesel engine on the Dongfanghong-75 and 802 tractors, the timing mark on the camshaft gear should be located at the position where the gear teeth of the camshaft gear positioning hole center line are offset counterclockwise by one tooth. At present, due to too many manufacturers producing agricultural machinery parts, the marks on the camshaft gears produced are often misplaced, such as marking the mark on the second tooth or the third tooth. Therefore, when performing timing gear assembly, special attention should be paid to whether the marks on the newly purchased gears are correct and cannot be installed blindly according to the marks. Otherwise, it will cause a change in the phase of the valve, making the engine difficult to start, and seriously affecting the power and economy of the engine, and even causing damage to the parts. Of course, the better way is not to buy such unqualified accessories; further, the best way is to not allow the production of such unqualified accessories. (Yang Tongquan) Aluminum piston can be checked by scale. According to the design requirements, the quality of the aluminum piston of the S195 diesel engine should be 0.86kg, but some inferior pistons are only 0. 65kg, the top thickness is only 7~8mm. There is a S195 type. After the diesel engine was replaced with this inferior piston, it worked less than three days and was scrapped due to cracks on the top of the piston. It can be seen that when there is doubt about the qualification of the aluminum piston, in addition to measuring the size, it can be over-scaled.
