Usage:

C4.4 L1K
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。

检查

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。

典型示例

  1. 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。

    典型示例

  2. 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。

  3. 将防护罩 (2) 与发动机对齐。 安装螺栓 (1)。 拧紧螺栓。

调整

  1. 松开螺母和螺栓 ( 1)。 然后松开螺母和螺栓 ( 2)。


    图 4g01626064

  2. 松开螺栓 (3),并调整交流发电机以改变皮带张力。 拧紧所有因调整交流发电机而松开的螺栓至 22 N·m (16 lb ft)

  3. 安装端盖。 更多信息,请参阅 "检查" 。
