Yes, it was made for the Cummins ISBe 6.7 diesel engine. Check the old fuel injector is marked 0445120018 or one of the cross references, because makers change parts between serial ranges.
On the Cummins ISBe 6.7 diesel engine, often 5,000 to 10,000 hours, but much less on poor or wet fuel. Injectors are usually changed when they fail a test, not by hours.
Black or white smoke, a misfire or knock on one cylinder, hard starting, higher fuel use, or a high return leak or balance rate on test.
Most common rail injectors carry a trim code (QR or IMA) printed on the body. Enter it with a diagnostic tool after fitting, or the engine runs rough and smokes.
Not always. If the others pass a return leak or balance test, one can be changed. Where they are all high hours, a full set keeps the cylinders even.
No. It is an aftermarket fuel injector made to replace the Bosch 0445120018. It is not made by the original manufacturer; the number only shows what it replaces.
