注: 发动机可能会自动起动。 进行任何维修或修理之前,确保电源已断开。
为获得发动机的最高性能,应检查传动皮带是否磨损和断裂。 更换磨损或损坏的皮带。
如果皮带太松,振动会对皮带和皮带轮产生不必要的磨损。

- 卸下螺栓 (1),并拆下防护罩 ( 2)。
对皮带进行检查和调整后,安装防护罩。
Show/hide table图 2 g01626059 典型示例 - 要检查皮带张力,请安装 144-0235 皮带张力表。 在最长自由长度的中心安装张力表 ( 3),并检查张力。
使用过的皮带正确张力为
355 N (79.8 lb) 。 如果皮带张力低于250 N (56 lb) ,调整皮带到355 N (79.8 lb) 。新皮带的正确张力为
535 N (120 lb) 。 为了补偿新皮带的弹力,需要更高张力。 只在未曾使用的皮带上使用较高张力。 使用过的皮带是指工作 30 分钟或更长时间的皮带。 - 将防护罩 (2) 与发动机对齐。 安装螺栓 (1)。 拧紧螺栓。
- 松开螺母和螺栓 ( 1)。 然后松开螺母和螺栓 ( 2)。
