The Optibelt S8M 688 is a timing belt with an STD profile and a length of 688 mm. Before you fit a new belt, inspect the drive and sheaves to confirm the replacement will run true.
Check the sheaves for worn grooves, nicks or debris that can damage the belt teeth. Confirm the new belt matches the old one by reading the marking on the back: S8M 688, profile STD, length 688 mm. Spin the drive by hand to verify alignment and that the belt seats correctly in the grooves.
If the drive shows misalignment, worn bearings or a failed tensioner, correct those issues before installing the new belt. A timing belt that runs on a compromised drive can wear quickly or fail. Once the drive is sound, fit the Optibelt S8M 688 and recheck tension and tracking.
