Product Advantages

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

Fitment-first matching

CF-20059N 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 20059 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-20059N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Caterpillar Ag. & Ind. 305 Mini Excavator, Caterpillar Ag. & Ind. 305.5 Mini Excavator, Caterpillar Ag. & Ind. 306 Mini Excavator and related applications.

Which fields matter most?

Start with Voltage: 24V, Amperage: 35A, Rotation: CW, Pulley Class: V2, then cross-check OE numbers Caterpillar 139-7850, Mitsubishi A003TA8199, Mitsubishi Heavy Industries ME108147.

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 20059. That usually narrows the match quickly.
