Product Advantages

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 DELCO and replacement references including 7801-3, 7872-3, 7937-3 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-7801-3N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Buick Skylark, Buick Somerset, Oldsmobile Calais and related applications.

Which fields matter most?

Start with Voltage: 12V, Amperage: 105A, Rotation: CW, Pulley Class: S4, then cross-check OE numbers Delco 10463003, 10463004, 10463102, 10463374.

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 7801-3, 7872-3, 7937-3. That usually narrows the match quickly.
