140154-3401 (KZ01) is a genuine-quality fuel injection plunger (plunger & barrel assembly) designed for Isuzu 4LE2 series engines, widely used in HITACHI, SANY, and SUMITOMO excavators and other construction equipment.
The plunger is one of the core precision components of the diesel engine fuel injection system. Installed inside the fuel injection pump (high-pressure pump), it is responsible for precisely metering and delivering high-pressure fuel to the injectors. The precision fit and wear resistance of the plunger directly determine injection timing, fuel delivery volume, and atomization quality, thereby affecting engine power output, fuel economy, and emissions performance. This plunger is specifically engineered for the demanding, high-load, continuous-operation conditions of excavators, featuring high-precision manufacturing for reliable fuel injection performance.

This plunger is compatible with equipment powered by Isuzu 4LE2 series engines, including:
HITACHI: ZX60, ZX70, ZX75US-5A, ZX60USB-5A, ZX65USB-5A
SANY: SY55, SY60, SY65, SY75, SY80
SUMITOMO: SH75-5 and other mini excavators
Other Equipment: Mini excavators, forklifts, generators, small loaders, and machinery equipped with 4LE2/4LE1 engines
Note: The above is a partial list of compatible models. Please verify against your engine model (4LE2) and fuel pump model. Confirm that your old plunger model is KZ01 before installation.
OEM Quality: Manufactured to Isuzu technical standards for precise compatibility with 4LE2 engine fuel pumps.
Precision Fit: Plunger and barrel are precision-machined with minimal clearance for high-pressure sealing and injection accuracy.
High Wear Resistance: Constructed from premium alloy materials with surface hardening treatment, maintaining precise clearance even after extended use.
Stable Fuel Delivery: Accurately controls fuel delivery volume and injection timing for consistent engine power output.
Direct Replacement: Standard OEM specification for hassle-free, bolt-on installation.
Broad Application: Fits HITACHI, SANY, SUMITOMO, and many other mainstream excavator brands.
The plunger is a precision component. Keep the work area absolutely clean during installation to prevent contaminants from entering the fuel pump.
Verify that the new plunger part number (140154-3401 / KZ01) matches the old unit before installation.
Professional installation is recommended. After installation, the fuel pump must be calibrated on a test bench to ensure proper fuel delivery volume and injection timing.
When replacing the plunger, it is recommended to also replace related fuel system components such as injectors for optimal performance.
