(1) 从前惰轮组件上拆下管螺塞，并施加空气压力到此端口。 前惰轮组件应保持 245 至 265 kPa (36 至 38 psi) 空气压力至少 30 秒钟。 添加 0.38 ± 0.02 L (0.100 ± 0.005 US gal) SAE 30-D 机油。 在管螺塞的螺纹上涂抹 4C-4030 螺纹固定剂 并安装管螺塞。
(2) 安装时，橡胶曲面密封和所有接触面必须清洁干燥。 组装之前，在金属密封环的接触面上涂一薄层 6V-4876 润滑剂 。 密封圈必须装配成方形。 橡胶曲面密封不能凸起也不能扭曲。
(3) 在 O 形密封圈上涂抹少量 SAE 30-D 机油。
(4) 安装环，确保切口在规定的范围内。 环的正确位置如图所示。
