730 EJ Model (3T4 Series) Maintenance Guide: Periodic Care for Sustained Efficiency

Hourly Maintenance: Control Wear, Prevent Failures

Operating hours are key for maintenance cycles. Targeted care is needed based on varying component wear over time.

4,000 Hours: Replace with 199L HYDO TO10 oil at 4,000 hours. Its excellent anti-wear and thermal stability suits harsh conditions and protects core engine parts.

5,000 Hours: Replace 378-3178 DEF filter at 5,000 hours. Check seal tightness post-replacement to prevent leaks.

6,000 Hours: Replace 83L ELC long-life coolant + 73oz (2.15L) extender; change 2x 248-5513 thermostats with 341-1429 seals. Ensure proper installation and sealing.

10,000 Hours: Replace 2x 506-5818 DEF manifold filters at 10,000 hours to ensure SCR efficiency.

12,000 Hours: Replace 83L ELC coolant + 73oz extender at 12,000 hours to remove impurities and restore heat dissipation.

3 years: Replace 566-5659 cab safety belt every 3 years to ensure reliable locking and operator safety.

Conclusion: Scientific Maintenance is Key
