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: 间隙检查完成后,先不要涂覆机油,安装连杆轴承。 最后组装时,在连杆轴承上涂覆清洁的发动机机油。
- 将连杆轴承的上轴瓦安装到连杆内。
- 将连杆轴承的下轴瓦安装到连杆内。
注: 将连杆轴承背面的凸键对准连杆上的凸键凹槽。
- 为了检查连杆轴承间隙,将工具 (A) 放置在连杆轴承上,如图所示。

- 拆卸连杆盖。 在拆下工具 (A) 前,测量轴承表面上的工具 (A) 。 连杆轴承和新的曲轴之间的间隙应为 0.076 至 0.168 mm (.0025 至 .0066 in)。 连杆轴承和使用过的曲轴之间的间隙应为 0.25 mm (0.01 in)。
- 将连杆盖 (2) 和连杆螺母 (1) 安装在连杆 (3) 上。 重复第 6 步,拧紧螺母。
- 对于其余的连杆轴承重复第 1 至 8 步。
