This Optibelt Alpha Flex timing belt is identified by the code 25 AT10K13 / 2500 AFX. It uses an AT10 profile and a 2500 mm length. Timing belts of this type are used in synchronous drive systems where the belt teeth mesh with matching pulleys to maintain position and speed.
To confirm fit, start with the belt you are replacing. Read the marking on the back of the old belt and compare the profile and length to the AT10 profile and 2500 mm length shown here. Check that the pulley grooves match the AT10 profile and that the belt width and tooth count suit the drive.
Inspect the drive before ordering. Look for worn or damaged pulley teeth, misalignment, and correct tension. If the drive runs more than one belt, replace the full set so the load is shared evenly.
