⚠️ Common Signs of Failure

• Coolant temperature climbing while the fan turns slowly or not at all
• Whine, growl or knock from the motor under load
• Hydraulic oil weeping from the shaft seal or casing joints
• Fan speed not following engine load
• Hydraulic oil overheating or discoloured

🛠️ Service Notes

• Check the hydraulic oil level, condition and the supply pressure before condemning the motor - low flow gives exactly these symptoms
• Flush the circuit if the old motor has broken up internally, or the debris will destroy the new one
