三、发动机标牌
发动机号码位于进气歧管的下方缸 体上。
四、驱动皮带
1、驱动皮带的位置
1-发动机 2-水泵/动力转向泵 3-压缩机 4-惰轮 5-曲轮轴 6-张紧轮
2、驱动皮带拆卸与更换
当更换成调整发电机传动带时,按照正确 的张紧度来调整传动带。传动带张紧度过大可 能导致交流发电机、动力转向泵带轮轴承的损 坏,而过松又会产生传动带打滑或早期磨损。
传动带更换时要将传动带恰当地绕在带轮 上。应在更换传动带之前留意到传动带的绕行 路径。
1)使用快速板手,将快速棘轮板手的接头插入 到皮带张紧轮上。
2)使用98N(221bf)的力施加在皮带张紧轮的 中间部位,其挠度应为9.0~11.5mm (0.35~0.45in)。
3)反方向压下快速扳手,松开张紧器,取出旧 的传动皮带。
4)安装时注意皮带的绕向,反方向压下 快速扳手,装入驱动皮带。
5)松开张紧器,检查皮带位置是否正确。
注: 传动皮带与张紧器总成对中的调整方法: ——用扳手旋转发动机曲轴皮带轮,让传动 皮带运行一周以上。
——观察传动皮带与张紧器总成对中情况, 如传动皮带中心超出张紧器总成的中心,拆 卸张紧器总成,加垫片进行调整。
