液压油箱 (1) 位于操作台后部。 下述系统共享一个公用液压油箱:推进液压系统, 风扇液压系统, 辅助液压系统, 喷水系统 和 乳化液喷洒系统。
目测表 (2) 指示油箱中的油位。 液压油箱的容量为 233 L (61.5 US gal)。 油箱配备有呼吸器 (3) 。 呼吸器将油箱中的最大压力限制为 50 ± 20 kPa (7.3 ± 3 psi)。 呼吸器也将油箱中可能形成的真空限制为不超过 2 ± 0.7 kPa (0.3 ± 0.1 psi)。 加注口 (4) 位于呼吸器后部。
油经过回油滤清器 (5) 从下述部件流入液压油箱:风扇回路箱体排油, 制动阀回油, 发动机罩提升阀回油 和 推进液压系统中的箱体排油管路。 滤清器壳体包括滤清器指示器 (6) 和旁通阀。 滤清器指示器显示滤清器是否需要维修。 当机器在正常操作条件下运转时,检查滤清器指示器。 如果滤清器指示器处于红色区域,更换滤清器。 如果滤清器前后的压差大于 172.5 kPa (25 psi),旁通阀开启,回油直接流入液压油箱。
