Before you fit a new timing belt, inspect the drive. Check the sheaves for worn teeth, debris in the grooves and any runout. Confirm the shafts turn freely and that the tensioner, if the drive has one, moves smoothly through its range. A worn or misaligned sheave will shorten the life of any new belt, including this Optibelt 100 AT5 / 4800 AFX.

Match the old belt to the new one by reading the marking on the back. The Optibelt 100 AT5 / 4800 AFX carries an AT5 profile, a 4800 mm length and a 5 mm pitch. If the old belt is unreadable, measure the length and confirm the profile before ordering. Send the part number, the profile and the length to MR by WhatsApp or email and the team will reply promptly to confirm the right belt.

When you replace a timing belt, check the whole drive. Look at the sheave teeth, the flanges and the shaft bearings. If the drive runs more than one belt, replace them as a set. After fitting, recheck alignment and tension before running the drive under load.
