Product Number: 22181N
The WAI 22181N is a brand-new 24V 100A alternator. It is built to replace the LETRIKA (ISKRA) original-equipment unit, reference 11.204.425. Designed as a direct OE replacement in the IR/IF (internally regulated, internally fan-cooled) configuration, it is engineered to restore correct charging output on the machines it serves without the cost of an OEM part.
Constructed to match the original specification, the WAI 22181N delivers 100 amps of output at 24 volts with clockwise rotation and is fitted with an S8 pulley — key parameters to verify against the outgoing unit before ordering. The IR/IF design means no external regulator is required; the regulator is integrated within the alternator body, simplifying installation and reducing component count on the vehicle.
The Lester reference for this alternator is 22181, which can be used to cross-check compatibility in standard industry catalogues. As a brand-new unit — not reconditioned or remanufactured — it carries no prior wear and is ready to fit straight from the box.

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 22181N is the direct OE replacement for LETRIKA (ISKRA) reference 11.204.425. This is the only OE cross-reference published for this part. You can also use the Lester number 22181 to verify the match in industry catalogues. If you need to confirm suitability by machine model, use our cross-referenced catalogue or ask Simon — every OE reference shown is backed by our Fit Guarantee.
A. The WAI 22181N runs at 24V with 100A output, clockwise (CW) rotation, and an S8 pulley. The design is IR/IF — internally regulated and internally fan-cooled — so no separate external regulator is needed. Before ordering, compare these figures against your outgoing unit or the machine's service data to confirm the fit.
A. Brand new. The WAI 22181N is supplied as a new alternator — not reconditioned or remanufactured — so it carries no prior wear and is ready to install directly.
A. IR/IF stands for internally regulated and internally fan-cooled. The voltage regulator is built inside the alternator body, which means there is no external regulator to wire or replace separately. This simplifies the swap — provided the machine originally used an IR/IF unit, which the LETRIKA (ISKRA) 11.204.425 is.
A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
