When you need to replace a timing belt, the first step is reading the marking on the back of the old belt. The Optibelt 3MHP 669 from the Omega HP series is a timing belt with an HTD 3M profile and a 669 mm length. Use the part number and profile to confirm it matches your drive before requesting a quote.
The marking on a timing belt typically shows the brand, part number, profile and length. For this belt, you will see Optibelt 3MHP 669, which corresponds to the Omega HP series, an HTD 3M profile and a 669 mm length. The 3 mm pitch is also part of the profile designation. If the old belt is worn or the print is illegible, measure the length and count the teeth to identify the correct replacement.
This timing belt is used in synchronous drives where exact timing and positive engagement are required. The HTD 3M profile is a common choice for compact, high-speed applications. When replacing a timing belt, inspect the pulleys for wear or debris and check the tensioner and idler bearings. Replacing the belt alone may not be enough if other drive components are worn.

- What does the HTD 3M profile mean?
- HTD 3M is a timing belt profile with a 3 mm pitch. It is used in synchronous drives where the belt teeth mesh with pulley grooves to maintain timing. This belt has a 669 mm length.
- Can I replace just the belt, or should I replace other parts?
