A     5P-3931     防粘结剂     -    


注意

检查涡轮增压器铭牌了解型号。 如果涡轮增压器铭牌上的型号或类型为 NA 297 或 Napier 297,使用 NA 297 涡轮增压器芯的安装步骤。


注: 如果喷嘴已拆下,执行步骤 1 至步骤5从涡轮增压器的压缩机侧安装喷嘴。

  1. 将喷嘴放到气体进口壳体中。

  1. 将夹紧环放到喷嘴上。 对齐各孔。

  1. 将工具 (A) 涂抹在螺栓的螺纹上。 将有头螺钉和锁紧垫圈安装到夹紧环中。 拧紧螺栓至扭矩为 67 N·m (50 lb ft)。

  1. 将护罩组件安装到气体出口壳体上。

  1. 将有头螺钉和锁紧垫圈安装到护罩组件中。 拧紧螺栓至扭矩为 30 N·m (22 lb ft)。

    注: 下文仅适用于前部涡轮增压器。 如果涡轮增压器芯 (5) 正被安装到发动机的气体出口壳体 (3) 上,务必正确放置 O 形密封圈。 将 O 形密封圈置于涡轮增压器支撑的机油排放口。 (以后设计去掉了 O 形密封圈,此类发动机使用一根插入到涡轮增压器支撑中的管路。)当更换涡轮增压器芯时,确保已从机油排放孔拆下了正确的护盖。 其它排放孔应塞上。

  1. 将芯组件安装到 (5) 气体出口壳体 (3) 中。

  1. 安装安装螺栓 (4) 。 拧紧安装螺栓 5 至扭矩为 492 N·m (365 lb ft)。

  1. 将螺母和垫圈安装到气体出口壳体 (3) 的柱塞上。 安装安全螺栓。

  1. 如有必要,连接备用的供油装置。

  1. 如有必要,安装备用的机油排放管。

  1. 如有必要,连接涡轮增压器清洗组件。

  1. 连接速度传感器接头。
