Komatsu SA6D114-1 Engine

Scanned with Komatsu diagnostic — boost, fuel pressure, injector timing all within spec. Engine has low idle noise and impressive torque. Fits perfectly in Komatsu HD465. Definitely not remanufactured — real OEM.

Working in hot dusty mines — this engine takes it like a champ. Fuel efficiency is solid for this size. Zero overheating, even during long full-load shifts. Mechanics call it “bulletproof”.

Powerful and quiet. We use this engine in a D155A bulldozer. Installed easily, connected without issues, no tuning needed. Oil pressure steady, no vibration. The turbo is smooth and responsive. Totally worth it.

Installed in a Komatsu quarry dump truck. Engine arrived in factory packaging, clean and untouched. Started quickly, pulls strong. Pressure and compression are perfect. Ideal for heavy-duty conditions.

Perfect for mining work. Engine came fully sealed and ready. Started first crank. Pulls heavy loads without RPM drop. Mechanics confirmed everything matches factory spec. Turbo works flawlessly.
