Cooling performance on compact excavators is directly tied to how consistently the radiator fan is driven under hydraulic control. The RITO 708-7S-00352 / 7087S00352 fan motor is engineered for PC60-7 / PC78MR-6 / PC78UU-6, converting hydraulic energy into controlled fan rotation to maintain stable airflow across the radiator core.

2-3 DAYSInstead of relying on fluctuating engine-driven airflow, this unit keeps fan speed aligned with system temperature demand. In high-dust or high-load environments, it helps prevent heat accumulation, supports steady engine breathing, and reduces the risk of thermal shutdown during long operating hours.
