| 项目 | 数量 | 零件 | 技术规格说明 |
| 1 | 1 | 349-2568 活塞环 | 安装顶部活塞环，同时使标有 "Up-1" 的一侧朝向活塞顶部。 顶部活塞环的端隙为 0.53 ± 0.10 mm (0.021 ± 0.004 in)。 新顶部活塞环的厚度为 3.845 mm (0.1514 in)。 |
| 2 | 1 | 344-5153 活塞环 | 安装中间活塞环，同时使标有 "Up-2" 的一侧朝向活塞顶部。 中间活塞环的端隙为 0.825 ± 0.125 mm (0.0325 ± 0.0049 in)。 新中间活塞环的厚度为 2.94 mm (0.116 in)。 |
| 3 | 1 | 246-5659 活塞环 | 装配控油环时，控油环末端应和环端隙相差 180 度。 槽与新机油控制活塞环之间的间隙为 0.55 ± 0.15 mm (0.022 ± 0.006 in)。 新控油环的厚度为 2.980 ± 0.010 mm (0.1173 ± 0.0004 in)。 新活塞体组件中用于安装控油环的槽宽为 3.020 ± 0.010 mm (0.1189 ± 0.0004 in)。 |
| 4 | 1 | 180-7350 活塞销 | 将活塞销插入活塞体组件和连杆组件中之前，先用清洁的发动机机油彻底润滑活塞销。 新活塞销的外径为 59.975 ± 0.005 mm (2.3612 ± 0.0002 in)。 新活塞销的内径为 25.4 ± 0.5 mm (1.00 ± 0.02 in)。 新活塞销的长度为 89.80 ± 0.15 mm (3.535 ± 0.006 in)。 新活塞体组件中用于安装活塞销的孔径为 60.125 ± 0.005 mm (2.3671 ± 0.0002 in)。 |
| 5 | 2 | 230-2569 销固定器 | 安装销固定器，同时使开口处于活塞底部，如图 1 中所示。 |
| 6 | 1 | 150-1156 专用螺栓 | 拧紧至扭矩为 25 ± 6 N·m (221 ± 53 lb in)。 |
| A | - | - | 在装配进缸体中之前，先使用清洁的发动机机油彻底润滑区域中的整个活塞。 |
| - | - | - | 活塞环安装完成之后，旋转活塞环，以便使各端隙之间成 120 度。 |
