The Dayco BB 81 is a double-V (hexagonal) belt in the BB profile with a length of 2133.6 mm. This page gives maintenance, engineering and purchasing teams the profile and length data needed to confirm the belt against a drive. The same size is also listed under Optibelt BB 81 and Gates BB 81.
The BB profile and 2133.6 mm length are the two values to check first. A double-V belt drives from both faces, so both sets of V-grooves in the pulleys must match the BB profile and the center-to-center distance must suit the 2133.6 mm length. Confirm these against the drive before ordering.
If the old belt is still on the drive, read the marking on the back and compare the profile and length with the BB 81. When the marking is worn or missing, measure the outside length and check the cross-section against the pulley grooves. The same size is also listed under Optibelt BB 81 and Gates BB 81 for cross-brand reference.
For a quote, send the part number BB 81, the quantity, and any drive details you have. The team can confirm the BB profile and 2133.6 mm length and help match the belt to the application.
