Product Number: 12157N
The WAI 12157N is a brand-new 24V 80A alternator. It is built to the Bosch IR/EF design, replacing original-equipment units referenced under Bosch 0 120 468 136, Bosch 0120468136, and Bosch USA AL5010N, among others. It is a direct-fit replacement for John Deere and Bell plant and agricultural machinery — covering 55 John Deere applications and 2 Bell applications — including models such as the John Deere 200LC Hitachi, John Deere 250D, John Deere 300D Backhoe, Bell 670CH, and Bell 770CH.
The unit delivers a clockwise rotation and is supplied without a pulley, so the original pulley transfers to the new unit on installation. Being brand new rather than remanufactured, there is no core charge and no uncertainty about internal wear.
