This alternator is a direct replacement for the original unit fitted to Toyota forklift trucks, superseding Toyota part number 27060-78202-71 and Denso 101211-3730. It is built to OEM specifications for fit, form and function, allowing straightforward installation in place of the original part.
The unit is rated 12-volt, 50-amp with clockwise rotation, an internal regulator (IR) and internal fan (IF). It uses a single-groove (V1) pulley measuring 76mm OD with a 15mm ID, designed to run on a 5/8 inch belt, and is fitted with an oval S-IG-L plug and a low L-terminal output. Matching the original pulley diameter and belt width helps keep the drive alignment and belt tension correct after installation.
