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 12877 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-12877N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Arctic Cat 4-Stroke Touring, Arctic Cat 4-Stroke Trail, Arctic Cat Bearcat Widetrack Turbo and related applications.

Which fields matter most?

Start with Voltage: 12V, Amperage: 45A, Rotation: CW, Pulley Class: S4, then cross-check OE numbers Arctco 3006-261, Arctic Cat 3006-261, Denso 101211-2880, Suzuki 31400-76G00.

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 12877. That usually narrows the match quickly.
