(1) 销
- 销会从左后凸轮轴处伸出以下距离： ... 12.0 ± 0.5 mm (0.47 ± 0.02 in)
(2) 垫圈
- 新垫圈的厚度 ... 8.50 ± 0.05 mm (0.335 ± 0.002 in)
- 新凸轮轴中凹槽的厚度 ... 8.75 ± 0.05 mm (0.344 ± 0.002 in)
- 新凸轮轴的端隙 ... 0.15 至 0.35 mm (0.006 至 0.014 in)
- 新凸轮轴中凹槽的厚度 ... 8.75 ± 0.05 mm (0.344 ± 0.002 in)
(3) 左凸轮轴
(4) 右凸轮轴
(5) 轴颈表面
- 新凸轮轴轴承表面（轴颈）的直径 ... 85.88 ± 0.02 mm (3.381 ± 0.001 in)
- 组装后的凸轮轴轴承孔孔径 ... 86.00 ± 0.06 mm (3.386 ± 0.002 in)
(6) 凸轮轴凸轮高度
请使用以下步骤来确定这一高度：
- 测量凸轮轴凸轮高度 (6) 。
- 测量基圆 (8) 。
- 用凸轮高度（步骤 2）减去基圆（步骤 1）。 二者之差即为实际凸轮升程。
- 规定的凸轮轴凸轮升程 (7)
进气凸轮 ... 9.314 mm (0.3667 in)
喷油器凸轮 ... 13.731 mm (0.5406 in)
排气凸轮 ... 9.078 mm (0.3574 in)
