Cummins 5271460 is the 24 V, 6.6 kW starter: a black cast nose housing with a 12 tooth pinion, a silver field frame and end frame, and a top mounted solenoid with a start relay. It is used on Cummins QSB6.7 engines. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.
