Cummins 4298626 Injector Camshaft Assembly

The Cummins 4298626 is an injector camshaft designed for the 15-liter ISX15, QSX15, and X15 engine platforms utilizing a Dual Overhead Cam (DOHC) architecture. This component controls the fuel injector actuation timing and is distinct from the valve camshaft in the same engine series. Manufactured from forged billet steel with induction-hardened lobes and journals, the camshaft achieves a surface hardness of approximately 55 HRC to withstand high-contact stresses in heavy-duty diesel applications. It serves as a direct replacement for Cummins OEM part numbers 4059331, 3680779, 4059170, 3680799, 4298627, and 4101432. Aftermarket manufacturing references include M-4298626 (Interstate-McBee), CU4298626, and R4298626. Primary applications include heavy-duty on-highway trucks equipped with ISX15 engines and off-highway construction machinery such as hydraulic excavators powered by QSX15 engines from OEMs including XCMG, SANY, SDLG, Zoomlion, Lovol, and Lonking. The unit is supplied new in a carton package measuring 120 x 20 x 20 cm with a net weight of approximately 19 kg.
