The Optibelt 1904 8M 85 HILO is an Omega High Load timing belt with an HTD 8M profile and a 1904 mm length. When you read the marking on the back of an old belt, this is the string to match: part number, profile, and length.
Start by cleaning the back of the belt and reading the full marking. The part number 1904 8M 85 HILO tells you the profile is HTD 8M and the length is 1904 mm. The 8 mm pitch is also part of the designation. If the old marking is worn or rubbed off, measure the length and confirm the profile before you request a quote.
The Optibelt Omega High Load series is built for drives that need a timing belt with a high load rating. The HTD 8M profile uses rounded teeth that engage the pulley grooves. This belt is identified by its 1904 mm length, so it is not interchangeable with a belt of a different length even if the profile looks the same.
Send the full part number 1904 8M 85 HILO, or the marking from the back of the old belt, by WhatsApp or email. If the marking is unclear, include the profile and length you measured. The team will confirm the belt and reply with a quote.

Frequently asked questions
- What does the marking on the back of the belt tell me?

- Can I use a different length timing belt if the profile is the same?
- No. This belt is 1904 mm long. A belt with the same HTD 8M profile but a different length will not fit the same drive. Always match the length and profile to the old belt.
