Product Number: 12346N
The WAI 12346N is a brand-new 12V 55A alternator. It is built to Denso IR/IF specification, replacing original-equipment units across 32 Caterpillar agricultural and industrial applications. It replaces Denso references including 101211-2240 and 101211-2310, Delco Remy DRA0337, and Caterpillar part numbers 0R4327, 0R9273, 1052811 and 1052812, making it a direct-fit choice for Caterpillar backhoe loader and construction plant fleets from the mid-1990s through to the 2010s.
Designed as a clockwise-rotation unit with a groove pulley, the 12346N is suitable for applications where the original Denso IR/IF alternator has been specified at 55A output. The internally regulated, internally excited design keeps the alternator self-contained and straightforward to install without additional external regulators.
Fitment covers 32 Caterpillar Ag. & Ind. models, including the 416C (1996–2000), 416D (1996–2001), 420D (2003–2006), 424D (2002–2006), 426C (1996–2000), 428C (1996–2001), 428D (2001–2004), and 428E (2006–2014), among others. Always verify the application against your machine's serial number before ordering.

The best way to find the correct starter motor is to combine the machine and engine details with the OEM or original starter reference, then confirm voltage, rotation, pinion teeth, mounting and terminal position. Do not choose a replacement from appearance alone.
A starter motor usually clicks without cranking because the battery cannot deliver enough current, resistance is present in the battery cables or engine ground, or the starter control circuit and solenoid are not operating correctly. A click does not automatically mean the...
