Product questions
Is Caterpillar 557-7627 a fuel injector or a fuel injection pump?
557-7627 identifies a fuel injector group, not a fuel injection pump. The exact-part description identifies it as a hydraulic H1315B fuel injector. Its function is fuel injection into the engine; H1315B is the injector designation associated with this reference.
Is the C7 engine name enough to confirm that injector 557-7627 fits my equipment?
No. Exact-part references associate 557-7627 with Caterpillar C7 engines, but they do not establish compatibility with every C7 configuration or serial-number range. Provide the engine serial number, machine model and serial number, and the reference on the removed injector for verification before ordering. Treat the published C7 association as a starting point, not a confirmed fitment.
