Description:

This fault code indicates that the hydraulic oil temperature sensor has detected oil temperatures higher than normal operating levels, but not yet reaching a critically hot threshold. This situation can still adversely affect system efficiency and increase wear on hydraulic components.

Reaction:

The function of the hydraulic system is degraded, limiting some operations to prevent damage due to elevated temperatures.

Recommendations:

• Check Hydraulic Oil Level: Verify that the hydraulic oil is at the proper level and top up if necessary. Low oil levels can lead to higher operating temperatures.
• Inspect Transmission Components: If the issue arises predominantly during transport speeds, inspect the transmission suction screen for clogging and the transmission scavenge pump for any damage or wear.
• Evaluate Cooling System: Ensure that the hydraulic system’s cooling components are functioning correctly and efficiently.
• System Monitoring: Monitor the hydraulic system during operation to identify potential causes of increased temperature, such as excessive load or insufficient cooling.
• Reset and Test: After performing necessary maintenance, reset the CCU and test the hydraulic system to ensure temperatures remain within normal ranges during operation.

Note:

Regular maintenance and monitoring of hydraulic oil levels and cooling systems are crucial to maintaining optimal temperatures and preventing overheating.
