Q: Is the 6251-11-3100 the same as Denso 095000-6070?
A: Yes, the Komatsu 6251-11-3100 fuel injector is manufactured by Denso and carries the Denso part number 095000-6070. This COGENG injector is a direct OEM replacement for both part numbers, designed for the 6D125 engine platform.
Q: What equipment uses the Komatsu 6D125 engine with this injector?
A: The 6D125 engine equipped with the 6251-11-3100 (095000-6070) injector powers a wide range of Komatsu heavy equipment, including PC400-7, PC450-7 excavators, D155A-6 dozers, and WA600-6 wheel loaders. Verify your machine's engine model and injector part number to confirm compatibility.
Q: What are symptoms of a failing 095000-6070 injector on a PC450-7?
A: Common signs include excessive black smoke under load, noticeable loss of engine power, rough idling or engine misfire, increased fuel consumption, and difficulty starting. A faulty injector can also cause fuel dilution in the engine oil, leading to accelerated internal wear.
