Product Advantages

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

Fitment-first matching

CF-12166N 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 BOSCH and replacement references including 12166 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.

Product matching notes

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

How do I confirm CF-12166N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Caterpillar Ag. & Ind. 120G, Caterpillar Ag. & Ind. 12G, Caterpillar Ag. & Ind. 130G and related applications.

Which fields matter most?

Start with Voltage: 24V, Amperage: 50A, Rotation: BI, Pulley Class: W/O PULLEY, then cross-check OE numbers Bosch 0 122 469 002, 0 122 469 004, Case 75263297, Caterpillar 5S 9088.

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 12166. That usually narrows the match quickly.
