(1) 变矩器、举升装置、制动器和变速箱液压油箱

(2) 变矩器、举升装置和制动器段

(3) 变速箱段

变矩器、举升装置、制动器和变速箱液压油箱 (1) 位于机架右侧的外面。 变速箱段 (3) 与变矩器、举升装置及制动器段 (2) 由液压油箱 (1) 中的一面内壁隔开。 变速箱段 (3) 为变速箱的运转提供机油。 变矩器、举升装置和制动器段 (2) 向制动器、制动器冷却系统、变矩器系统及举升装置液压部件提供机油。 制动器段 (2) 的通气装置和变速箱段 (3) 的通气装置位于卡车右侧的直立机架构件上。

变矩器、举升装置和制动器段 (2) 有两个液位标尺。 顶部的液位标尺通常用于检查油位。 当举升装置液压油箱处于 RAISE 位置时,可以使用底部的液位标尺。 变速箱段 (3) 也有两个液位标尺。 底部的液位标尺用于检查冷油的油位。 顶部的液位标尺用于检查热油的油位。 有关液压油箱这两段部件的润滑剂粘度及续加注量,请参阅运行和维护手册。
