The marking on the back of an old belt is the fastest way to identify a replacement. This Dayco AX 78 is a cogged classical V-belt in the AX profile with a length of 2032 mm. The same size is also listed under Optibelt AX 78 and Gates AX 78.
When you read a belt, look for the profile and the length. Here the profile is AX and the length is 2032 mm. The AX profile is a classical V-belt section, and the cogged construction is typical of raw-edged industrial belts in the Dayco line. Write down the full marking before the old belt is discarded.
If the marking is worn or missing, measure the outside length and check the cross-section against the pulley groove. The AX profile sits in a specific groove range, so confirm the belt you remove matches the drive. Send the part number, the profile and the length you read, and the team can confirm the right belt or suggest an equivalent.
This belt is supplied as a Dayco AX 78. The same size is also listed under Optibelt AX 78 and Gates AX 78. For a quote, send the part number by WhatsApp or email. If you are replacing more than one belt on the same drive, include the quantity and the position so the set can be matched.
