Product Number: 12445N
The WAI 12445N is a brand-new 12V 70A alternator. It is built to Bosch IR/IF specification, designed to replace original-equipment Bosch units — including Bosch 0 124 315 030 and Bosch 0 124 315 042 — across 33 John Deere applications. It is a direct-fit replacement for skid steer loaders, compact utility tractors and related plant equipment where the original Bosch, Iskra / Letrika or John Deere alternator has reached end of life.
The IR/IF (internal regulator, internal fan) design keeps the voltage regulator and cooling system self-contained within the unit, simplifying installation and eliminating the need for external regulator wiring. Clockwise rotation and a groove pulley configuration match the original drive arrangement, so the unit drops in without modification. At 70 amps output the WAI 12445N meets the electrical demand of the machines it replaces, supporting charging under sustained field or site loads.
Across 16 verified cross-references, this alternator replaces units from Bosch, Iskra / Letrika, Mahle, AD Kühner, DRI and John Deere. Confirmed John Deere applications include the 244J, 304J, 313, 315, 325 Skid Steer Loader, 328, 4120 and 4320, covering model years from 2000 to 2012 — 33 applications in total.
