Product Number: 20111N
The WAI 20111N is a brand-new 24V 50A alternator. It is built to the Mitsubishi IR/EF design, supplied as a direct replacement for Mitsubishi original-equipment units including A4TU3599 and 34368-03800. It is engineered for heavy-duty agricultural and industrial plant machinery, covering seven Caterpillar Ag. & Ind. applications from the 317B through to the 324D series.
Constructed to OE specification, the 20111N delivers clockwise rotation and is fitted with a groove pulley, matching the mechanical and electrical configuration of the units it replaces. The IR/EF (Internal Regulator / External Fan) design keeps the charging system compact and reliable under the demanding duty cycles typical of excavators and loader variants in long-term field or site operation.
Cross-references confirmed for this unit include Mitsubishi A4TU3599, Mitsubishi 34368-03800, Mitsubishi 3436803800, Mitsubishi A004TU3599, CAT 212-8561, Caterpillar 2128561, AD Kuhner 554381RI, Farcom 112825, Sando 20356220, and Sando 20356221 — ten references in total across six OE and aftermarket brands.
