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

    弹簧压缩零件如果安装不当,会伤害人体。

    为避免伤害,遵照出版的装配程序,并穿上保护装备。


  2. 在内转子 (4) 的表面和惰轮齿轮 (3) 的叶片上涂敷清洁的发动机机油。

  3. 对正惰轮齿轮 (3) 上的正时标记 (X) 与齿轮 (19) 和 (20) 上的相应正时标记。 将惰轮齿轮 (3) 安装到惰轮轮毂 (1) 上。

  4. 将内转子 (4) 安装到惰轮齿轮 (3) 上。

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

    突然释放弹簧作用力可能会导致人身伤害。

    驱动轴、活塞和传动齿轮都受到弹簧力的作用。

    在拆卸部件前,使用压具慢慢释放弹簧作用力。


  5. 将以下部件安装到惰轮轮毂 (1) 上:

    • 机油泵盖 (5)

    • 垫片 (6)

    • 弹簧 (7)

    • 套圈 (8)

    参考图 3。

  6. 将挡圈 (9) 安装到惰轮轮毂 (1) 上。
