Common Excavator Fault & Solution
Fault: Excavator hydraulic system overheating, leading to reduced performance and potential damage.
Details: Overheating can be caused by several factors, including a clogged hydraulic oil cooler, low hydraulic fluid levels, a faulty hydraulic pump, or issues with the hydraulic system relief valve.
Solution:
Check Hydraulic Fluid Level: Ensure the hydraulic fluid is at the correct level. Low fluid can lead to overheating.
Inspect Hydraulic Oil Cooler: Check for any blockage or debris on the oil cooler. Clean the cooler thoroughly.
Examine Hydraulic Pump: A failing pump can generate excessive heat. Inspect the pump for unusual noises or leaks, and consider professional inspection or replacement.
Test Relief Valve: A malfunctioning relief valve can cause continuous cycling of hydraulic fluid, leading to heat build-up. Test and replace if necessary.
Regular Maintenance: Implement a schedule for hydraulic system maintenance, including fluid changes and filter replacements, to prevent future overheating issues.
