RITO Hydraulic Fan Motor 708-7S-00352 7087S00352 Cooling Motor PC60-7 PC78MR-6 PC78UU-6 Excavator Radiator Fan Motor

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.

Instead 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.

FAQ


QWhat indicates hydraulic fan motor malfunction?
A: Engine temperature rises quickly, fan speed becomes irregular, or cooling efficiency drops.
 
QWhy is hydraulic cooling preferred on excavators?
A: It provides variable-speed cooling that matches real-time thermal demand more effectively than fixed drive systems.

 

 
QWhat should be inspected before installation?
A: Hydraulic pressure supply, hose condition, fan blade balance, and motor mounting alignment.
 
Q: Can this improve overheating issues?
A: Yes, restoring proper fan drive control significantly improves engine cooling stability.
 
Q: What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
