Product Number: 12377N
The WAI 12377N is a brand-new 24V 140A alternator. It is built to Bosch IR/EF specification, replacing original-equipment numbers including Bosch 0 120 689 548, Bosch 0 120 689 552, and Bosch 0 120 689 566 — among 45 OE and aftermarket cross-references in total. It is a direct-fit choice for buyers sourcing a Bosch-pattern alternator for heavy-duty agricultural and plant applications.
Manufactured to the internal regulator / external fan (IR/EF) design, this alternator delivers a robust 140-amp output at 24 volts, making it well suited to the electrical demands of larger diesel-powered machinery. The unit is supplied without a pulley, so the existing serviceable pulley is retained during installation — a practical arrangement that simplifies the swap and avoids the cost of components that are typically still in good condition.
Fitment data records the WAI 12377N against the Renault Ares tractor (1998–2000). Cross-reference data additionally links this alternator to Remy references 19025337, 19025361, and 19025367; Iskra numbers AAT1310, AAT1330, and IA0902; Mahle Original MG333 and MG382; and Daf 1254010, among others. Buyers holding any of these part numbers can confirm a match via our cross-referenced catalogue.
