Practical Maintenance Tips for Model 725 (3T9 Series): Master Core Cycles to Keep Equipment Running Stable Longer

As a core equipment in production work, the stable operation of the 725 model (3T9 series) directly affects efficiency and cost, but many users have the problem of heavy use and light maintenance.

Next, I will bring you a customized maintenance guide for this device. From cognition to practical operation, it can help you extend the lifespan of equipment and improve operational efficiency. It's full of practical knowledge. Let's take a look together.

Short-cycle maintenance is the "cornerstone" of stable equipment operation, focusing on core lubrication and filtration systems, replacing worn parts promptly to prevent impurity buildup from impairing equipment performance.

• Every 4,000 hours: 178L  HYDO TO10 Oil (multi-system lubrication, high wear resistance)

• Every 5,000 hours: 378-3178 DEF Filter (filters impurities, protects SCR exhaust system)

• Every 6,000 hours: 83L  ELC Coolant + 318-0004 Thermostat (core only, no seals; temperature control, anti-scaling)

• Every 10,000 hours: 584-8135 DEF Manifold Filter (deep filtration, prevents nozzle clogging)

• Every 3 years: 566-5659 Cab Seat Belt (mandatory replacement, safety guarantee)

• Every 12,000 hours: 83.2L  ELC Coolant + 73 oz (2.15L) Coolant Extender (restores anti-corrosion performance)

The stable operation of the 725 model (3T9 series) is inseparable from the precise control of every maintenance node.If you have more maintenance experience, welcome to leave a message in the comment area to share!
