Product Number: 11839N
The WAI 11839N is a brand-new 12V 120A alternator. It is built to the Letrika (Iskra) IR/EF design standard, supplied as a direct replacement for original-equipment units referenced across the Deutz, Iskra, Letrika, Mahle, and Agco catalogues. With 24 cross-references on record — including Deutz 0118 3868, Iskra / Letrika commercial IA1473, and Mahle MG 165 — this unit covers a broad range of industrial and agricultural applications where the original Letrika or Iskra alternator is specified.
Clockwise rotation and a 120-amp output make this a high-capacity charging solution suited to demanding engine environments. The IR/EF design (internal regulator, external fan) is the standard Letrika/Iskra architecture, and WAI's brand-new manufacture means no rebuilt core, no worn brushes, and no aged regulator — just a unit ready to fit straight from the box.
Cross-references span Letrika's own catalogue families (11.204.779, IA 1473, AAK3869, AAK4954, AAK4990), legacy LetrikaOLD numbers (11.204.137, 11.204.717), Deutz engine references (0412 3607, 0412 4784), Agco 3972 863 M1, and trade catalogue numbers including Lester 11839 and PIC 282-739 / 282-739A / 282-739B.

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. The WAI 11839N is cross-referenced against six Deutz original-equipment numbers: Deutz 0118 3868, Deutz 01183868, Deutz 0412 3607, Deutz 04123607, Deutz 0412 4784, and Deutz 04124784. If your Deutz engine currently carries one of these part numbers on its alternator, the 11839N is the listed replacement. Search our catalogue by your Deutz part number to confirm, or ask Simon if you are unsure.
A. Yes — the WAI 11839N is cross-referenced to the Mahle MG 165. It is manufactured brand new to the same Letrika (Iskra) IR/EF design specification, 12V and 120A output, clockwise rotation. If your application currently uses an MG 165, the 11839N is the listed equivalent.
A. This is a brand-new 12V alternator producing 120 amps of output, built to the Letrika (Iskra) IR/EF design — internal regulator, external fan, clockwise rotation. It is supplied new (not remanufactured), so there is no worn core or aged internal components.
A. The WAI 11839N is brand new — not remanufactured, not rebuilt. It is manufactured to the Letrika (Iskra) IR/EF design specification and supplied unused, so you are not dealing with a reconditioned core or previously worn components.
A. Use the selection widget to match your make, model and engine, or search our cross-referenced catalogue by OEM number, machine model or equivalent part across brands. If your vehicle is not listed, ask Simon. Every fitment shown is backed by our Fit Guarantee.
