Product Number: 14887N
The WAI 14887N is a brand-new 12V 120A alternator. It is built to Letrika (Iskra) IR/EF specification, designed as a direct replacement for original-equipment units cross-referenced to Case, Iskra, Mahle, and Letrika. With 11 verified OE references across those manufacturer families, this unit is the trusted choice for technicians sourcing a like-for-like swap without compromise.
Constructed to IR/EF (internally regulated, externally fan-cooled) design, the 14887N delivers 120 amps of output at 12 volts with clockwise rotation — matching the original specification precisely. The groove pulley configuration ensures correct belt engagement on the applications for which this alternator was originally fitted, so installation follows the same procedure as the OE unit.
Supplied brand new, this alternator carries the assurance of a fresh unit rather than a reconditioned exchange, eliminating the condition variables that can accompany remanufactured cores. OE cross-references include Case 84281043, Iskra references 11204635, IA1454, AAK4919 and AAK3852, Mahle MG 138 and MG138, and Letrika references 11.204.635 and 11.204.099 — confirming broad interchangeability across the original-equipment families this part serves.

Exploring the WAI Starter Motor and Alternator at Partsformachines.com Introduction: In the Plant and Agriculture sector, a starter motor and alternator are parts that ensure a machine runs smoothly. At Partsformachines.com we have partnered with WAI, a global manufacturer of auto and plant machinery parts to off...
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...

A. Yes. Case reference 84281043 is one of 11 verified OE cross-references for the WAI 14887N. The unit is built to Letrika (Iskra) IR/EF specification as a direct replacement for that original-equipment number. To confirm fitment to your specific machine, use the selection widget or search our cross-referenced catalogue by OEM number or machine model — every cross-reference shown is backed by our Fit Guarantee.
A. The 14887N carries five Iskra references — 11204635, IA1454, AAK4919, 11204099, and AAK3852 — and two Mahle references: MG 138 and Mahle Original MG138. Letrika references 11.204.635 and 11.204.099 are also confirmed, giving 11 verified OE cross-references in total. If you are searching by one of these numbers, this is the corresponding brand-new replacement unit.
A. The WAI 14887N operates at 12V with a 120-amp output. It runs clockwise rotation and uses a groove pulley for belt engagement. The design is IR/EF — internally regulated and externally fan-cooled — matching the original Letrika (Iskra) unit specification. It is supplied brand new.
A. This is a brand-new alternator. It is not a remanufactured or reconditioned exchange unit, so there is no core return required and no uncertainty about the condition of internal components.
A. IR/EF stands for internally regulated, externally fan-cooled. Internal regulation means the voltage regulator is built into the alternator body rather than being a separate external component, simplifying the installation. External fan cooling means the unit draws cooling air from outside rather than relying solely on an internal fan arrangement — this is the same design as the original Letrika (Iskra) unit it replaces.
A. Compatible spares and accessories are shown on the Related Accessories tab of this product page, and common parts across the brands we stock are in our Parts & Spares section.
A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
