Yes, it was made for the Caterpillar C7.1 diesel engine. Check the old fuel injector is marked 295050-0360 or one of the cross references, because makers change parts between serial ranges.
On the Caterpillar C7.1 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.
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.
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.
No. It is an aftermarket fuel injector made to replace the Denso 295050-0360. It is not made by the original manufacturer; the number only shows what it replaces.
