When a timing belt needs replacing, the marking on the back of the old belt is the fastest way to identify what the drive requires. This page covers the Optibelt 25 AT10K13 / 5000 AFX from the Alpha Flex series, a timing belt with an AT10 profile, a 5000 mm length and a 10 mm pitch. Read the old belt carefully and compare each element against these figures before ordering.

The AT10 profile and the 10 mm pitch describe the tooth form and spacing that must match the pulleys on the drive. The 5000 mm length is the belt's own dimension, so it needs to agree with the old marking rather than be estimated from the machine. The 25 AT10K13 / 5000 AFX code is the reference to quote; if the back of the old belt shows the same code, the identification is straightforward.

Markings can be worn, oil-stained or partly rubbed away, so clean the back of the belt and read it in good light before removing it. Photograph the marking and note the profile, length and pitch so they can be checked against the figures above. If the belt has been replaced before with something else, the current marking may not reflect the original specification.

Send the part number, the photos of the marking and the profile, length and pitch you read from the old belt. Our team replies to quote requests by WhatsApp or email and can confirm the right belt or suggest an equivalent where one exists.
