Description
OPTIBELT 30 / 8M 4000 AFX belongs to timing belt, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 30 / 8M 4000 AFX and any equivalents.
This Optibelt Alpha Flex timing belt is identified by its 30 / 8M 4000 AFX code. The profile is HTD 8M and the length is 4000 mm, with an 8 mm pitch. Those three values are what you match to the drive before anything else.
The 8M profile is a metric HTD tooth form. The 4000 mm length is the datum for the replacement. If your old belt is marked 8M 4000, this is the same size. Confirm the width from the existing belt or the drive drawing, because the code carries a 30 that must line up with the pulley groove.
A timing belt does not stretch to take up misalignment. Before ordering, check the pulleys for worn teeth, the flanges for contact marks, and the tensioner for smooth travel. If the belt shows a clean break or missing teeth, look for a seized accessory or a jammed idler rather than assuming the belt failed on its own.
Send the full code 30 / 8M 4000 AFX, or a photo of the back of the belt, and we will confirm the Optibelt Alpha Flex timing belt against it. If you are replacing more than one belt on the same drive, send every code so the set stays matched.

- How do I read the marking on the back of my old belt?
- Look for the full code. This belt is marked 30 / 8M 4000 AFX. The 8M and 4000 identify the profile and length; the 30 relates to the width.
