Product Number: 12427N
The WAI 12427N is a brand-new 12V 120A alternator. It is built to the Marelli A127IM-120A IR/IF design, intended as a direct replacement for worn or failed units on Case and New Holland Industrial machinery. With 19 applications across those two makes — including the Case MXM series and New Holland Industrial TM115 — this is a well-matched choice for agricultural and plant operators needing a reliable charging system restore.
Constructed to internal regulator/internal fan (IR/IF) specification, the 12427N delivers 120 amps of output at 12 volts and turns clockwise, matching the drive arrangement of the original equipment. The groove pulley fitment ensures compatibility with standard multi-ribbed belt configurations found across the supported machine range.
Cross-references cover 28 OE and aftermarket references, including numbers from MAN, Delco Remy, Case, Marelli, Iskra / Letrika, and Mahle, making it straightforward to verify this unit against an existing part number or workshop catalogue entry.
