Product Number: 8440N
The WAI 8440N is a brand-new 12V 90A alternator. It is built to replace Ford original-equipment units referenced 1S7T-10300-BA, 1S7T-10300-BB and 1S7T-10300-BC, among 9 Ford OE references in total. Designed for Ford IR/IF (internal regulator, internal fan) applications, it is the direct-fit choice for a wide range of Ford passenger cars — 74 Ford applications and 2 Jaguar applications are covered, spanning multiple Mondeo III variants across petrol and diesel engine families from 2000 onwards.
The 8440N is built to the RC28 series specification, turning clockwise with an S6 multi-groove pulley that suits standard Ford ancillary drive configurations. The IR/IF design eliminates external regulator and fan components, keeping installation straightforward and reducing potential failure points. Lester numbers 11321 and 8440 index this unit in trade catalogues for workshop reference.
Ford Mondeo III (B5Y) applications include engines from the 1.8 SCi through to the 2.2 TDCi — covering both petrol and diesel variants ranging from 66 kW to 114 kW output. Use the fitment selection tool or search by OE reference to confirm coverage for your specific engine code before ordering.
