Product Advantages

Alternator matching focuses on amperage, voltage, pulley configuration, regulator/fan design, plugs, and OE replacement references.

Fitment-first matching

CF-12658N is prepared for alternator sourcing with Part No, OE, Lester number, and application records checked together.

Quality and test focus

Core specifications such as voltage, power or amperage, rotation, teeth, and design are reviewed before sample or bulk quotation.

Replacement sourcing support

MFR DENSO and replacement references including 12658 help buyers compare existing units and reduce wrong-part risk.

Inquiry-ready supply

Share target quantity, destination, sample need, and packaging requirement so Crankvia can confirm the practical supply path.

Application Information

Application records are provided as compatibility references. Confirm OE number, vehicle configuration, engine, and market version before final ordering.

How do I confirm CF-12658N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Ag-Chem 6103 TERRAGATOR, John Deere 6081AFM75, John Deere 6125AFM75 and related applications.

Which fields matter most?

Start with Voltage: 12V, Amperage: 140A, Rotation: CW, Pulley Class: S8, then cross-check OE numbers Denso 101211-7780, John Deere RE500226, SE501839, Mercury Marine 8M6007489.

What if I only have a photo or partial number?

Share label photos, drive-end and connector shots, and any partial number or Lester Numbers 12658. That usually narrows the match quickly.
