Denso 101211-2951 is the 12 V alternator with a single V belt pulley and plug-in regulator connector. It is used on Yanmar 3TNV88 and 4TNV94 engines, including Hyundai R60-5 and R60-7 mini excavators. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
The same part is also sold as Yanmar 119626-77210.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.
