When a timing belt needs replacing, the marking on the back of the old belt is the most reliable starting point. This page covers the Optibelt 16 AT5K6 / 11400 AFX, an Alpha Flex timing belt with an AT5 profile, a 11400 mm length and a 5 mm pitch. Use these figures to confirm the belt matches your drive before you request a quote.

The AT5 profile and 11400 mm length define the belt's fit on the pulleys. The 5 mm pitch is the distance between tooth centers, so it must match the pulley groove spacing exactly. If the old belt's marking reads AT5 and 11400, this Optibelt Alpha Flex belt is the correct profile and length to specify.

Timing belts wear gradually, and a belt that has lost tension or skipped teeth can affect the entire drive. Inspect the pulleys for worn grooves, check the tensioner and idler bearings, and look for cracks, glazing or missing teeth on the belt itself. Replacing the belt before it fails helps avoid unplanned downtime.
