Product Number: 12814N
The WAI 12814N is a brand-new 24V 80A alternator. It is built to the Magneti Marelli IR/IF specification, replacing original-equipment units from Denso, Delco Remy, Remy, Caterpillar and Magneti Marelli across 29 applications — 28 Caterpillar agricultural and industrial machines plus one Terex model. Caterpillar machinery fitted includes excavator and paving machine platforms such as the 312D2L, 315C, 318D2L and AP650B. Cross-referenced Caterpillar numbers include CAT 346-9826 and Caterpillar 3469826 among 48 verified OE references in total.
Designed as a direct OE replacement, the 12814N features an internal regulator and internal fan (IR/IF) design for clean, maintenance-free charging. Clockwise rotation matches the OE drive configuration, and the unit is supplied without a pulley so the original pulley is reused — preserving correct belt alignment and eliminating unnecessary cost. Being brand new, it carries no core charge and requires no exchange.
With 48 cross-references spanning Denso (including 102211-8140, 102211-8150, DAN651, DAN652), Delco Remy (DRA0031, DRA0032), Remy (8600686) and Magneti Marelli (063377465010, 063377466010, 63377465, 63377466), buyers can confirm fitment by OE number or machine model via our cross-referenced catalogue.
