Product Number: 12687N
The WAI 12687N is a 12V 80A replacement alternator. It is built to the IR/EF (internally regulated, externally fan-cooled) design standard, manufactured by LETRIKA (ISKRA) and supplied brand new. It replaces LETRIKA (ISKRA) original-equipment reference 11.203.888, making it a direct OE-equivalent choice for plant and agricultural machinery operators who need a reliable, like-for-like charging system component.
Fitted with a clockwise rotation and supplied without a pulley — meaning the original pulley is retained during installation — this alternator is engineered to match the electrical and mechanical specification of the unit it replaces. The IR/EF design locates the voltage regulator internally, simplifying the charging circuit and reducing external wiring complexity on compatible machines.
In terms of vehicle fitment, the 12687N is confirmed across eight applications spanning three makes: Agco (four applications, including the LT70 and LT85), Challenger (two applications, including the MT345B), and Massey Ferguson (two applications, including the MF 3635). This makes it a practical stock choice for dealers and workshops servicing this spread of agricultural machinery.
The alternator is supplied as a standalone unit. Lester number 12687 provides an additional cross-reference point for workshop catalogues.
