Problem Description
A user reported that on their Kobelco Model 35 SR-2 excavator, one track drives significantly slower than the other. This speed discrepancy was causing difficulties in maneuvering and operation.
Potential Causes
Community members suggested several possible causes for the uneven track speed. Common issues included low hydraulic flow to one track, a failing or clogged hydraulic motor, problems with track tension, or mechanical binding in the undercarriage.
Hydraulic System Checks
Advice was given to inspect hydraulic fluid levels and condition first. Testing the hydraulic motors and valves on each side could help identify if one motor is losing pressure or efficiency. Checking for leaks or damaged hoses was also recommended.
Mechanical Inspections
Some users emphasized inspecting the tracks, rollers, and sprockets for damage or excessive wear that could impede movement. Ensuring proper track tension and alignment was noted as critical for smooth operation.
Diagnostic Tips
Using pressure gauges and flow meters to compare output on both sides was suggested to pinpoint hydraulic issues. Additionally, observing any unusual noises or resistance during operation could indicate mechanical faults.
Conclusion
When one track on a Kobelco 35 SR-2 runs slower than the other, systematic checks of the hydraulic and mechanical systems are necessary. Proper diagnosis and maintenance can restore balanced track speeds and improve machine control.
