组装步骤

表 1
需要的工具    
工具     零件号     零件说明     数量    
A     1P-1861     挡圈钳     1    
B     1P-1863     挡圈钳     1

注意

保持所有零件清洁无杂质。

杂质会造成快速磨损和缩短部件寿命。


注: 清洁度是一项重要的因素。 组装之前,应彻底清洁所有零部件。 检查所有零件。 如果任何零件磨损或损坏,则应使用新件进行更换。 必须在清洁的工作面上及清洁的液压区域中进行所有的解体和组装步骤。 总是盖好并保护好清洁的零件。

注: 在组装之前必须先使用丝锥清理所有需要使用密封胶的螺纹。

注: 务必更换 O 形密封圈、密封垫和密封。 旧 O 形密封圈的密封性能可能不如新 O 形密封圈。 在组装过程中使用 1U-6396 O 形密封圈装配附着剂 。

注: 在组装之前先使用润滑剂润滑要密封的所有部件。
