Diagnosis Steps

To effectively diagnose issues with a John Deere S670 combine, follow these structured steps:

1. Visual Inspection

   • Check for visible leaks in hydraulic systems.
   • Look for wear signs on belts and augers.

2. Review Error Codes

   • Use the onboard diagnostic system to retrieve any error codes.
   • Common codes include:
     • SPN 126 - Engine Oil Pressure
     • SPN 414 - Motor Speed Indicator

3. Functional Testing

   • Test all hydraulic functions to identify unresponsive components.
   • Conduct an engine start check to evaluate starting performance.

4. Fluid Checks

   • Inspect oil, hydraulic fluid, and coolant levels for necessary adjustments.
   • Ensure filters are clean and free from debris.

5. Examine Controls

   • Verify that all control settings are correctly calibrated for the harvest conditions.
   • Assess any dashboard readings for anomalies.

A thorough diagnosis can pinpoint the root cause and guide subsequent actions.

Troubleshooting and Repair Procedures

Once the issues are diagnosed, appropriate troubleshooting methods may follow:

• Engine Issues

  • Problem: Engine won’t start.
    • Solution:
      • Inspect the battery; replace if necessary.
      • Check the fuel system for blockages or ensure fuel quality.
      • Replace faulty ignition components.

• Hydraulic Failures

  • Problem: Unresponsive hydraulic systems.
    • Solution:
      • Assess hydraulic fluid levels; top up if low.
      • Check for leaks and replace damaged hoses or connectors.
      • Test the hydraulic pump for functionality.

• Grain Quality Issues

  • Problem: Poor grain sample quality.
    • Solution:
      • Adjust settings according to the crop type.
      • Clean out any blockages in the intake and auger systems.
      • Inspect and replace worn-out components.

• Mechanical Maintenance

  • Problem: Excessive wear on belts.
    • Solution:
      • Replace belts regularly during maintenance intervals.
      • Ensure proper tension is maintained to prevent slippage.

Regular maintenance and immediate response to issues will foster efficiency and reliability.

Estimated Repair Costs

Understanding the potential costs associated with repairs can better prepare owners for maintenance decisions. Some estimated repair costs include:

• Battery Replacement: $200 - $400
• Hydraulic Pump Repair/Replacement: $1,500 - $3,000
• Engine Overhaul: $5,000 - $10,000
• Minor Electrical Repair: $100 - $500
• General Maintenance (Filters, Fluids): $500 - $1,500 annually

Costs may vary based on location, parts availability, and labor charges. Always consider obtaining multiple quotes for significant repairs.

Prevention Tips

Prevention is the best strategy to minimize issues with your John Deere S670 combine. Consider the following tips:

• Regular Maintenance: Stick to a strict maintenance schedule, including changing fluids, filters, and worn components.
