Denso original Denso Diesel Fuel Injector Assy 095000-6280 6219-11-3100 Replacement for OEM SAA6D170 650-8R 450-7 Engine Parts new injector original new injector

The DENSO 095000-6280 common rail fuel injector is engineered as a direct OE replacement for KOMATSU 6D170, SAA6D170, and SAA6D170E 23.2L heavy-duty diesel engines installed in the HD785-7 mining dump truck and WA900-3 wheel loader. It carries authorized cross references including 095000-6281, 9709500-628, 6219-11-3100, 6219113100, R6219-11-3100, and 6219-11-310#, allowing it to be specified against KOMATSU official reman reference R6219-11-3100 and related SAA12V140 documentation while remaining a true Original Type replacement for the 6D170 platform.

Built around electronically controlled high-pressure common rail technology, this injector delivers precise fuel quantity, injection timing, rail pressure, and injection rate control. Accurate metering and fine atomization support stable combustion, improved fuel economy, controlled smoke output, and dependable load response when the injector is correctly matched to the engine calibration. Its construction follows DENSO OE design intent, making it suitable for mining truck repair, heavy equipment fleet maintenance, diesel workshop service, engine rebuild, and broader common rail fuel system repair operations.

Reliable long-term performance depends on clean diesel supply, regular fuel filter replacement, periodic water separator draining, and clean fuel tank and line conditions. Before replacement, technicians should conduct return-flow testing, rail-pressure diagnosis, cylinder-balance analysis, harness inspection, fuel contamination inspection, and bench testing if symptoms such as hard starting, rough idle, black or white smoke, high fuel consumption, low power, misfire, or excessive return fuel are observed.
