Product Number: 12582N
The WAI 12582N is a brand-new 12V 85A alternator. It is built to the Marelli IR/IF design, supplied as a direct replacement for Case original-equipment numbers 47134024, 47134024R and 500364130, as well as Marelli references 63321744 and 63321822. It is the correct specification for operators sourcing a dependable, ready-to-fit alternator matched to Case agricultural and plant machinery that carries those OE references.
The IR/IF (internal regulator, internally fan-cooled) design means all regulation is handled within the unit itself, keeping the installation straightforward and eliminating the need for a separate external regulator. At 85 amps output on a 12-volt system, the unit delivers the charging capacity specified for the original Marelli fitment it replaces.
Supplied brand new — not remanufactured — the WAI 12582N gives operators a clean-slate replacement with no residual wear from a previous service life. WAI is a specialist alternator and starter-motor manufacturer, and this unit is produced to meet the Marelli IR/IF specification exactly.
