The Optibelt 25 AT5K6 / 5800 AFX is an AT5 profile timing belt with a 5800 mm length and a 5 mm pitch. Before you fit it, inspect the drive and sheaves so the new belt runs on a sound system.
Check the sheaves for wear, burrs, or debris in the grooves. Confirm that the sheave teeth match the AT5 profile and that the 5 mm pitch aligns with the drive. Any damaged sheave should be addressed before installation.
Verify that the 5800 mm length is correct for your layout. A belt that is too long or too short will not tension properly, even if the profile is right. Compare the marking on the old belt with the 25 AT5K6 / 5800 AFX to confirm the match.
When you request a quote, send the part number 25 AT5K6 / 5800 AFX, the profile AT5, the length 5800 mm, and the pitch 5 mm. If you have the old belt, include a photo of the back marking. Our team can help confirm the right belt for your drive.
