- 拆卸前壳体。 拆下 C 形夹 (1)。
注: 拆下前壳体之后，不要转动曲轴。
- 拆解发动机机油泵。 有关更多资料，请参阅拆解和组装, "发动机机油泵 - 拆卸"。 没有观察到损坏的情况下不要从惰轮 (10) 上卸下衬套 (9)。
- 清洁所有零件并检查零件的金属部分有无裂纹或是其他损坏。 检视部件有无磨损。 确保惰轮 (10) 中的衬套 (9) 没有松动。

(1) C 形夹
(2) 套环
(4) 垫片
(12) 塞尺 - 使用塞尺 (12) 测量 C 形夹 (1) 与套圈 (2) 间的距离。
- 发动机机油泵部件安装在前壳体上时，C 形夹 (1) 和套圈 (2) 之间的新部件测量值 (B) 必须在
0.10 to 0.15 mm (0.004 to 0.006 inch) 之间。 旧零件的尺寸 B 不得超过0.20 mm (0.008 inch) 。表面间的距离通过垫片 (4) 调节。 垫片的厚度由技术规格, "发动机机油泵"中给定。

图 4 g00826185 - 将发动机机油泵的部件和前壳体安装到缸体上。 确保两个定位销与衬套、外转子和惰轮上的孔对齐。
将惰轮安装在机油泵轴上时，对齐惰轮 (10) 上的正时标记 (15) 与曲轴齿轮 (16) 上的正时标记。 此外，还要对齐惰轮 (10) 上的另一个正时标记 (15) 与凸轮轴齿轮 (13) 上的正时标记。 机油泵盖 (5) 上的孔 (14) 应与前壳体上的定位销对齐。
注: 若前壳体未安装在发动机上，请勿转动曲轴。
