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 21104 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-21104N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around John Deere 344K, John Deere 344L, John Deere 5075M and related applications.

Which fields matter most?

Start with Voltage: 12V, Amperage: 90A, Rotation: CW, Pulley Class: S8, then cross-check OE numbers Bosch 0 124 325 207, 0 124 325 225, 0 124 325 249, John Deere 150CT13.

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 21104. That usually narrows the match quickly.
