Product Number: 12187N
The WAI 12187N is a brand-new 12V 35A alternator. It is built to Denso IR/IF specification, replacing original-equipment alternators across 63 applications — 62 Toyota and 1 Lamborghini-Agricultural. It carries OE cross-references for Denso, Delco Remy, Toyota, Remy, DRI, Hella, and Unipoint, making it a trusted like-for-like replacement for any of those OE units.
Constructed to match the original Denso internal-regulator, internally-fused (IR/IF) design, the 12187N delivers 35 amperes of charging output at 12 volts. Clockwise rotation and a groove-pulley configuration ensure direct installation without modification. As a brand-new unit rather than a remanufactured exchange, there is no core charge and no worn internals to contend with.
Fitment spans Toyota forklift and materials-handling models including the 2FG-7, 2FG-9, 4SG-10, 4SG-12, and 4SG-15, as well as the Lamborghini-Agricultural 603 DT.

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...
