  1. 将挺杆杆体 (1) 放置于液压机内。

  2. 将发动机机油涂敷于挺杆 (1) 的内孔和适配器 (2) 的孔上。 将适配器 (2) 按压至杆体 ( 1) 内。 装配后,适配器的顶部应与杆体 (1) 的顶部齐平。

    注: 安装销后,将垫片放置于挺杆和滚轮间。 以防杆体的叉具弯曲,这一点非常必要。

  3. 将滚轮 (5) 放置于挺杆 (4) 的叉具间。 将这两个部件放置于压力机内,并使锁线槽位于顶部。

  4. 将导线安装至销 (3) 内,且两端超出的长度相等。

  5. 用清洁的发动机机油润滑销 (3)。

  6. 将导线与挺杆 (4) 的叉具上的槽对齐。

  7. 将销 (3) 压缩至挺杆 (4) 和滚轮 ( 5) 中。

  8. 将推杆镶圈安装在挺杆杆体 (4) 内。

  9. 将新导向弹簧 (9) 和导向弹簧 (11) 安装在挺杆上。

    注: 如果从阀挺杆上卸下导向弹簧,则不能再次使用导向弹簧。

  10. 将挺杆 (7)、 (8 )及 ( 10 )浸入清洁的发动机机油内。

    正确的气门挺杆方位。

  11. 将阀挺杆 (7 )和 ( 10) 安装在原始位置。 安装气门挺杆,使零件号朝外。 气门挺杆方位正确可确保导向弹簧处于正确位置。

    注: 使用大钳子压缩导向弹簧 (11),以便将阀挺杆组件安装至阀导管 (6) 内。
