1.更换齿轮要注意正反面齿轮室共有6只齿轮,每只齿轮的正面都刻有钢印记号,装配时应保证齿轮有记号的一面是正面。若新换的齿轮无钢印记号,则凸轮轴齿轮、起动轴齿轮有凸台台肩的一面为正面;调速齿轮、平衡轴齿轮的正面为一个大平面,曲轴齿轮内孔倒角小的一面为正面。然后再根据旧齿轮上记号的相应位置。在新齿轮上重新做上记号。齿轮装反后,会带来不良后果。如凸轮轴齿轮装反会使配气时间发生变化,起动齿轮装反会缩短其使用寿命。 2.齿轮装配顺序及注意事项装配齿轮时,先把飞轮盘到上止点,凸轮轴油泵
1. Replace the gear to pay attention to the front and rear gear room a total of six gears, each gear is engraved with a steel seal on the front mark, assembly should ensure that the gear side of the mark is positive. If the new gear without steel imprint, the camshaft gear, the starter shaft gear has a boss shoulder side is positive; speed gear, balance shaft gear front is a large plane, crankshaft gear chamfer small side Positive. Then according to the old gear mark the corresponding position. Re-mark the new gear. After the gear is installed, it will bring undesirable consequences. Such as anti-camshaft gear fitted anti-gas valve will change the time, starting gear anti-assembly will shorten its service life. 2. Gear assembly sequence and precautions When assembling the gear, the first flywheel plate to the top dead center, camshaft oil pump
