Product Number: 12854N
The WAI 12854N is a brand-new 12V 55A alternator. It is built to Denso IR/IF specification, designed to replace Denso original-equipment units including reference 101211-2780 (also listed as 1012112780) across Caterpillar agricultural and industrial machinery. It is a direct-fit replacement carrying cross-references to Caterpillar 1449952, AD Kuhner 553196RI, and Sando 20403780, covering 11 Caterpillar Ag. & Ind. applications in total.
Constructed to match the original IR/IF (internal regulator, internally fan-cooled) design, the 12854N delivers a regulated 55-amp output and is fitted with a groove pulley to suit the belt drive arrangement on compatible machines. Being brand new, it requires no core return and carries none of the uncertainty associated with remanufactured units.
Verified applications include the Caterpillar 216, 226, 232 and 242 compact loaders alongside the 301.5, 301.6, 301.8 and 302.5 Mini Excavators, spanning model years from 1998 through to 2008. Use the selection widget or search the cross-referenced catalogue by OEM number or machine model to confirm fit for your specific unit.

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.
