- 从曲轴主轴承盖 (2) 上拆下曲轴主轴承的下半部分。
- 利用下述步骤拆下曲轴主轴承的上半部分:
- 转动曲轴,使工具 (A) 能够安装在曲轴轴颈中。 安装工具 (A) 。
- 转动曲轴,以便拆下曲轴主轴承的上半部分。 为了先将凸舌取出,曲轴必须按正确的方向旋转。
- 检查曲轴主轴承的状况。 请参阅再使用零件和修补操作指南, SEBF8009, "主轴承和连杆轴承"以及专门出版物, SEBD0531, "发动机轴承和曲轴"。

如果曲轴按错误的方向旋转,曲轴主轴承的锁键会在曲轴和缸体之间移动,这可能导致曲轴和缸体同时或其中之一损坏。 |
注: 一些曲轴主轴承轴颈没有油孔。 安置一薄片不会损坏抵在轴承端部的轴颈的软质材料。 确保此材料位于轴承凸舌的相对侧。 用软质材料敲打轴承,使轴承凸舌脱离缸体中的轴承凸舌槽。
