| 凸轮轴标有 "F" 的一端必须处于发动机前部。 用 8T-2998 润滑剂 和清洁的发动机机油的 50/50 混合剂润滑凸轮轴轴承、轴颈和凸轮。 | |||
| A | - | - | 凸轮轴轴颈的直径为 84.85 ± 0.02 mm (3.341 ± 0.001 in)。 |
| B | - | - | 请使用以下程序得出实际的凸轮升程： 1. 测量凸轮轴凸轮高度 (C) 。 2. 测量基圆 (D) 。 3. 从步骤 3 中得到的凸轮轴凸轮高度值中减去步骤 2 中得到的基圆测量值。 二者之差即为实际凸轮升程。 规定的凸轮轴凸轮升程 排气凸轮为 8.51520 mm (0.33524 in)。 喷油器凸轮（右排）为 10.33667 mm (0.40695 in)。 喷油器凸轮（左排）为 10.33718 mm (0.40697 in)。 进气凸轮为 9.61850 mm (0.37868 in)。 步骤 3 中得出的实际凸轮升程与规定的凸轮轴凸轮升程之间的最大允许差值为 0.13 mm (0.005 in)。 |
