When you are replacing a timing belt, the most reliable starting point is the marking on the back of the old belt. The Optibelt 20 / 8M 5000 AFX is an HTD 8M profile timing belt with a 5000 mm length, and that code is what we match against. Send us the part number and we will confirm it for your drive.
This belt is identified by three things: the profile, the pitch and the length. It is an HTD 8M profile with an 8 mm pitch and a 5000 mm length. The 20 / 8M 5000 AFX code on the back of the belt carries that same information, so the cleanest way to match a replacement is to read the old belt directly rather than measure a worn one.
If the marking is unreadable, check the drive for the belt's profile and count the teeth if you can. A belt that has run for a long time may measure differently from its original length, so the part number is the better reference. When you send the code, we can confirm the right Optibelt belt or suggest an equivalent.
Before the new belt goes on, inspect the pulleys for wear, check alignment and confirm the tensioner moves freely. On drives that use more than one belt, replace them as a set so they wear evenly. If you are unsure which code you need, send a photo of the old belt marking and the drive details.

Frequently asked questions
- How do I match this belt to the one I am replacing?
- Read the code on the back of the old belt. If it reads 20 / 8M 5000 AFX, this is the same profile and length. Send that code to us and we will confirm it.
- What if the marking on the old belt is worn off?
- Look for the profile and pitch on the drive, and check the belt's tooth count if possible. Send those details along with a photo and we can help identify the correct belt.
- Can you supply an equivalent if this exact belt is not what I need?
- Yes. We carry Optibelt belts and can suggest an equivalent based on the profile, pitch and length you provide. Send the part number or the drive details for a quote.
