简介

以下步骤用于检查终传动止推垫圈的磨损。

检查准备工作

------ WARNING! ------

吊装或垫塞不当可能会造成人员伤亡。

当使用起重机或千斤顶顶升任何零件或部件时,与之保持距离。 确保起重机或千斤顶具备正确的部件吊装能力。 在沉重部件下面进行任何工作之前先安装垫块或台架。

图上显示的是部件的近似重量。 清洁要安装零件的所有表面。


------ WARNING! ------

机器突然移动,会造成人员伤亡。

机器突然移动,会对机上或机器附近的人员造成伤害。

在处理机器之前,执行以下程序,以防止可能的伤害。


  1. 将机器停放在水平地面上。

  2. 接合行车制动器使机器停下。 将变速箱操纵杆移至空档位置。

  3. 将变速操纵杆移至低怠速位置。

  4. 接合停车制动器。

  5. 停止发动机。

  6. 将发动机起动开关转到断开位置,然后拔出钥匙。

  7. 将蓄电池断路开关转到断开位置。

检查程序

    查看机器通道与外罩之间的空隙

  1. 将机器放在水平地面上,记录从外罩或后机架到纵列传动箱内侧顶角的距离。

    注: 确保机具都抬起,使机器重量完全落在轮胎上。

  2. 将机器后端从地面抬起。 对外罩和通道使用相同的参考点,记录尺寸 (B)。

  3. 从步骤 2 中的值中减去步骤 1 中的值,记录差。 两者的差即为纵列传动箱下垂度的测量值。

  4. 如果纵列传动箱下垂度测量值达到表 1 中提供的测量值,请安排立即翻新,以防止方形或顶帽壳体损坏。

    表 1
    型号  纵列传动箱下垂度 
    120K  5 mm (0.20 inch) 
    12K  5 mm (0.20 inch) 
    140K  5 mm (0.20 inch) 
    160K  5.5 mm (0.22 inch) 

  5. 对机器的另一侧重复此步骤。
