(1) 凸轮齿轮 |
(2) 凸轮轴
- 新曲轴的轴向间隙 ... 0.13 ± 0.08 mm (0.005 ± 0.003 in)
- 磨损凸轮轴的最大允许轴向间隙 ... 0.46 mm (0.018 in)
(A) 新凸轮轴轴承轴颈的直径 ... 65.126 ± 0.013 mm (2.5640 ± 0.0005 in)
(B) 板
- 新板的厚度 ... 4.7 mm (0.19 in)

(C) 凸轮轴凸轮规定升程
- 排气凸轮 ... 6.858 mm (0.2700 in)
- 进气凸轮 ... 8.655 mm (0.3407 in)
按照以下步骤确定实际凸轮轴凸轮升程:
- 测量凸轮轴凸轮高度 (D) 。
- 测量基圆 (E) 。
- 从凸轮轴凸轮高度 (D) 中减去基圆 (E) 。 二者之差就是实际凸轮轴凸轮升程。
新凸轮的实际凸轮高度和规定凸轮高度的最大可允许差值 ... ± 0.10 mm (0.004 in)
