About this part
The Cummins Leece-Neville Alternator 24V 150A — part number 3640732 is a genuine Cummins part, supplied at £549 by G Service Power. It is brand new, held in UK stock and dispatched next day, worldwide.
Genuine Cummins heavy-duty alternator, part number 3640732, a 24 volt, 150 amp Prestolite Leece-Neville unit — the Cummins label reads 3640732 / serial 201737 / 150 A / 24 V and the Prestolite plate reads Model 8RL3028, Sales No. 105-408 (see photos). The alternator is belt-driven off the engine and charges the batteries and supplies the 24 volt electrical system while the engine runs, so on a generator set it is the part replaced when the starting batteries stop holding charge or the alternator fails on its rectifier, regulator or bearings. 3640732 is the Cummins-supplied alternator for the K38 / K50 family — KTA38, KTA50, QSK38 and QSK50 generator sets and industrial engines — and has been superseded in the Cummins catalogue by 4372405, which this unit replaces directly. The pulley nut torque, 70 to 80 ft lb, is cast into the drive end. Condition: brand new and unused in its Cummins Genuine Parts box, dated 30 December 2023, 10.2 kg boxed. Price £549 plus VAT. Prestolite alternators are specified by mounting, pulley and ground polarity as well as output, so please confirm 3640732 against your engine serial number before ordering. In UK stock — call +44 7951 632187 or message on WhatsApp for shipping and availability.
