The Dayco AA 68 is a double-V (hexagonal) belt in the AA profile with a length of 1778 mm. This page covers what those two figures tell you when you are selecting a replacement or specifying a new drive.
The profile identifies the belt's cross-section and the length of 1778 mm defines the belt's path around the pulleys. Both values need to match the drive before you order: an AA profile belt will not sit correctly in a pulley cut for another profile, and the length determines whether the belt tension can be set within the drive's adjustment range.
Because this is a double-V (hexagonal) belt, it is designed to contact pulleys on both faces, which suits drives that run on more than one plane or use reversing pulleys. Confirm the existing belt's marking on the back before ordering so the profile and length you send match the belt being replaced.
The same size is also listed under Optibelt AA 68 and Gates AA 68. If you are comparing options, those are the equivalent size listings to reference alongside the Dayco part.
