The Optibelt 25 / 8M 3400 AFX is an HTD 8M timing belt from the Alpha Flex series, 3400 mm long with an 8 mm pitch. The most reliable way to order the correct replacement is to read the marking on the back of the belt you are removing and match it to this part number.

Before you request a quote, confirm the profile and length on the old belt. This belt is HTD 8M with a 3400 mm length and an 8 mm pitch. If the back of the belt shows 25 / 8M 3400 AFX, it is the same item. If the marking is worn or unreadable, measure the length and count the teeth to confirm the profile before ordering.

Timing belts are often replaced as part of a drive service. Inspect the pulleys for worn teeth, check the tensioner, and look for oil or debris in the drive. If the drive runs more than one belt, replace them as a set so the load stays even. Send the part number and the quantity you need by WhatsApp or email, and the team will confirm the belt and reply with a quote.
