Product Number: 12786N
The WAI 12786N is a brand-new 12V 95A alternator. It is built to Letrika (Iskra) IR/IF specification, cross-referenced against 34 OE and aftermarket references including Delco Remy DRA1023, JCB 320/08560, Iskra AAK5813, and Mahle MG38. It is designed as a direct-fit replacement for J.C. Bamford plant machinery — specifically the 2CX, 3CX, and 4CX models spanning the 2007–2012 production window — making it a dependable choice for contractors and fleet maintainers keeping JCB backhoe loaders on the job.
Manufactured by WAI, one of the largest independent specialists in rotating electrics, the 12786N is supplied in brand-new condition — not remanufactured or reconditioned. The IR/IF (internal regulator, internally fused) design means the voltage regulator is integrated into the unit, eliminating the need for external regulator replacement and simplifying installation. The groove pulley is matched to the original drive-belt configuration, so fitment is straightforward without adaptation.
With a 95-amp output at 12 volts, this alternator handles the electrical demands typical of compact construction plant with hydraulics, lighting rigs, and cab electronics running simultaneously. The Letrika (Iskra) heritage of the design means it shares the dimensional and electrical envelope of the original OE unit across a broad family of Iskra and Letrika references.

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...
