This belt replaces worn, broken, or missing drive belts in Commodore 1530/1531 and Commodore PET Datasette tape decks.
The counter drive belt is separate, and size varies depending on the version of the C2N. See the related products for replacement counter belts.
Early PET cassette drives also have a reversing belt, available seperately. These drives are characteristic in that they appear to be repurposed standalone cassette recorders with cases featuring microphone & speaker provisions, and a large portion of the recorder case notched for clearance.
