Product Number: 12166N
The WAI 12166N is a brand-new 24V 50A alternator. It is built to Bosch IR/EF specification, designed as a direct replacement for original-equipment alternators across a range of heavy-duty plant and agricultural applications. With 22 cross-referenced part numbers on file, it covers Bosch, Delco Remy, Caterpillar, Case, John Deere, New Holland, Volvo, and further OE equivalents — making it a confident like-for-like substitute for sourcing teams working across mixed-fleet environments.
The unit features internal regulation and external fan (IR/EF) design, bi-directional rotation for installation flexibility, and is supplied without a pulley so that the original pulley can be transferred directly from the outgoing unit. At 24V and 50A output it is well matched to the electrical demands of diesel-powered construction and agricultural machinery typically running 24V systems.
Supplied as a complete, brand-new alternator — not a remanufactured or reconditioned unit — it is ready to fit once the original pulley is re-fitted.
