(1) 排气凸尖
(2) 以下尺寸位于上图所示位置。
- 新止推垫圈厚度 ... 4.70 mm (0.185 in)
- 至 ... 4.76 mm (0.187 in)
- 新凸轮轴轴向间隙 ... 0.10 ± 0.08 mm (0.0039 ± 0.0031 in)
- 磨损凸轮轴的最大可允许轴向间隙 ... 0.46 mm (0.018 in)
- 至 ... 4.76 mm (0.187 in)
(3) 进气凸尖
(4) 凸轮轴轴颈直径 ... 65.126 ± 0.013 mm (2.5640 ± 0.0005 in)

(5) 凸轮高度
- 排气凸尖 ... 6.858 mm (0.2700 in)
- 进气凸尖 ... 8.655 mm (0.3407 in)
采用以下步骤来确定凸轮高度：
- 测量凸轮轴凸尖高度 (6) 。
- 测量基圆 (7) 。
- 将步骤 2 中得到的基圆数值从步骤1中得到的凸轮轴凸轮高度中减去。 差值是实际的凸轮生成 (5) 。
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 (.004 in)
