| 342-6366 活塞和连杆总成 的技术规格 | |||
| 项目 | 数量 | 零件 | 技术规格说明 |
| 1 | 1 | 334-1158 活塞环 | 安装时将标有 "UP-1" 的一侧朝向活塞顶部。 |
| 新的顶部活塞环的厚度为 3.93 mm (0.15472 in)。 |
|||
| 在组装到孔径为 130 mm (5.1 in) 的新缸套中时，端隙为 0.51 ± 0.05 mm (0.020 ± 0.002 in)。 |
|||
| 缸套孔径每增加 0.03 mm (0.001 in)，间隙便增加 0.09 mm (0.004 in)。 |
|||
| 2 | 1 | 331-6025 活塞环 | 安装时将标有 "UP-1" 的一侧朝向活塞顶部。 |
| 新活塞环的厚度为 2.980 ± 0.010 mm (0.1173 ± 0.0004 in) |
|||
| 活塞中的槽宽为 3.0525 ± 0.0125 mm (0.12018 ± 0.00049 in)。 |
|||
| 在组装到孔径为 130 mm (5.1 in) 的新缸套中时，端隙为 1.00 ± 0.10 mm (0.039 ± 0.004 in) |
|||
| 缸套孔径每增加 0.03 mm (0.001 in)，间隙便增加 0.09 mm (0.004 in)。 |
|||
| 3 | 1 | 265-1113 活塞环 | 应该将弹簧圈的端部与机油控制活塞环的端隙成 180 度放置。 从机油控制活塞环端隙中必须能看到弹簧圈中的绿色条纹。 |
| 新机油控制活塞环的厚度为 3.980 ± 0.010 mm (0.1567 ± 0.0004 in)。 |
|||
| 活塞中的槽宽为 4.052 ± 0.012 mm (0.1595 ± 0.0005 in)。 |
|||
| 在组装到孔径为 130 mm (5.1 in) 的新缸套中时，端隙为 0.45 ± 0.15 mm (0.018 ± 0.006 in)。 |
|||
| 缸套孔径每增加 0.03 mm (0.001 in)，间隙便增加 0.09 mm (0.004 in)。 |
|||
| - | 活塞环安装完成之后，旋转活塞环使各端隙之间成 120 度。 | ||
| 装配到缸体中之前，在区域 (C) 360° 润滑整个活塞。 使用清洁的发动机机油。 | |||
| 4 | 1 | 197-9327 活塞销 | 装配前，用清洁的发动机机油彻底润滑活塞销。 |
| 直径为 53.155 ± 0.005 mm (2.0927 ± 0.0002 in) |
|||
| 孔径 (D) 为 53.250 ± 0.010 mm (2.0965 ± 0.0004 in)。 |
