Description

 

The 124-7634 is a genuine CAT (CAT) OE engine assembly, tailored for heavy-duty excavators and compatible with CAT 3406, 3408, 3412 platforms. As the core of large excavators, it integrates cylinder block, crankshaft, fuel system and other key components, precisely matched to meet the demands of construction, mining and infrastructure projects.
Built to CAT’s strict QC standards, it endures extreme conditions (-30°C to 50°C, dusty environments, high loads) and delivers stable power for digging, rock breaking and bulk handling. Each unit undergoes dynamometer, leak and endurance tests to meet OE specs, avoiding risks from non-original rebuilds.

 


Advantage

  • Perfect OE Compatibility: 100% fit for 3406/3408/3412 excavators, with matching mounting points and interfaces. Plug-and-play installation cuts downtime significantly.
  • Heavy-Duty Durability: Reinforced cast iron block, forged steel crankshaft and wear-resistant components extend service life by 50% vs. aftermarket rebuilds; fuel system tolerates low-quality fuel.
  • Efficient Power: CAT ACERT tech provides high low-RPM torque (critical for digging) and reduces fuel consumption by 10-15% vs. older versions.
  • Comprehensive Assurance: Backed by CAT’s global warranty, serial number traceable, meets EU Stage IIIA/China National III emissions to avoid compliance risks.

Performance

  • Strong Power Output: Delivers 300-500 HP and 1200-2000 N·m torque, enabling 250 kN bucket force and 20% higher efficiency. Stable performance at up to 3000m altitude.
  • Stable Operation: Advanced cooling system maintains 85-95°C under heavy load; balanced components reduce vibration/noise. Mechanical wear stays within 5% of OE limits after 10,000 hours.
  • Low Maintenance: 500-hour oil change intervals, 20,000-25,000-hour overhauls. Annual failure rate <1%, far below 10% industry average for non-original engines.
  • Operator-Friendly: Smooth power and low vibration enhance comfort. Integrates with excavator ECU for auto idle and load-sensing, optimizing fuel use; reliable cold start (-30°C) with pre-heater.
