Product Advantages

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

Fitment-first matching

CF-12431N 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 MITSUBISHI and replacement references including 12431 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.

Product matching notes

Use these checks together with the application table before final ordering.

How do I confirm CF-12431N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Caterpillar 307, Caterpillar 320B N, Caterpillar 320B and related applications.

Which fields matter most?

Start with Voltage: 24V, Amperage: 25A, Rotation: CW, Pulley Class: V1, then cross-check OE numbers Mitsubishi A005T70383, Mitsubishi Heavy Industries ME049165.

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 12431. That usually narrows the match quickly.
