This Isuzu 4BG1TC (TCG as a specific configuration identifier) engine assembly is the original power core for Hitachi ZX120 excavators, compatible with sub-models such as ZX120/-3, with common original part numbers including CC-4BG1TC series (e.g., YA00051958). A 4-cylinder in-line water-cooled diesel structure with a displacement of 4.329L and a rated power of 66kW/2150rpm, it adopts direct injection + turbocharging technology, featuring abundant low-speed torque and excellent fuel economy, serving as the core power source to ensure efficient operation of 12-ton excavators.

It adopts a high-strength alloy cast iron cylinder block, nitrided for outstanding wear resistance and deformation resistance. Key components such as pistons and connecting rods are made of forged steel, combined with a high-precision fuel injection system, ensuring high combustion efficiency and compliance with emission standards. Suitable for working conditions from -25°C to 45°C, it has a service life of over 8,000 hours without major overhauls, adapting to medium and heavy-load scenarios such as municipal administration and infrastructure. It operates without leakage or abnormal vibration for a long time, with excellent reliability and durability.

It strictly matches the original installation interface and flywheel housing size of ZX120, enabling quick replacement without additional modification. The assembly replacement can be completed in 2-3 hours with special lifting tools, significantly reducing downtime. Its stable power output can increase excavation efficiency by more than 12% and reduce fuel consumption by 6%-10%. Meanwhile, it reduces the impact on the hydraulic system, extends the service life of core components such as the main pump and distribution valve, and lowers the overall comprehensive maintenance cost of the machine.
