This DENSO 095000-6140 common rail diesel fuel injector is engineered as a direct OE replacement for Komatsu SAA6D140E and SAA6D140E-5 engines, carrying the authorized OE number 6261-11-3200 (6261113200). The injector is electronically controlled and operates within a high-pressure common rail fuel system, delivering pressurized fuel from the high-pressure pump into the common rail accumulator before precisely spraying it into each combustion chamber. It fits Komatsu PC800-8 and PC850-8 excavators and is also applicable to D155A / D155AX bulldozers, which should be confirmed before order placement. Cross-references supported under this part include 095000-6140, 0950006140, 6261-11-3200, 6261113200, 095000-6141, 095000-6142, and DLLA138P920.
The unit provides high injection pressure, precise injection timing, and accurate fuel quantity control, supporting efficient combustion and stable engine performance. Built to OE tolerances, the injector maintains consistent spray pattern and metering, making it suitable for excavator repair, mining equipment maintenance, quarry machinery service, heavy construction equipment overhaul, and B2B aftermarket distribution. It is designed for use in common rail injector testing programs and can be supplied to wholesale diesel parts importers, repair workshops, and heavy equipment service centers.
As common rail injectors operate at significantly higher pressures with tighter tolerances than older mechanical units, correct installation and contamination control are critical. Injectors must remain sealed, capped, dry, and dust-free, and protected from impact until installation. Clean diesel, proper fuel filtration, water separation, and accurate injector coding are required. Symptoms such as hard starting, rough idle, black or white smoke, knocking, power loss, excessive return fuel, high fuel consumption, misfire, external leakage, diesel dilution, or rail pressure deviation may indicate injector-related issues; the full fuel system, including filter, high-pressure pump, rail pressure sensor, metering valve, pressure relief valve, wiring harness, intake, turbocharger, compression, and ECU commands, should also be evaluated.
