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 21933, 22292, 22564 help buyers compare existing units and reduce wrong-part risk.

Inquiry-ready supply

Product matching notes

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

How do I confirm CF-21933N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around JLG G10-43, JLG G6-42A, JLG G9-43A and related applications.

Which fields matter most?

Start with Voltage: 12V, Amperage: 135A, Rotation: CW, Pulley Class: S8, then cross-check OE numbers China Made JFZ1135-111, Cummins 5262499, 5262871, 5272666.

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 21933, 22292, 22564. That usually narrows the match quickly.
