The Optibelt 477 3M SL 450 is an HTD timing belt with a 3M profile, a 477 mm length and a 3 mm pitch. When you read the marking on the back of the old belt, confirm each of these values before you request a quote.
The marking on the back of a timing belt is the most direct way to identify a replacement. On this Optibelt belt, the marking shows the part number 477 3M SL 450, which corresponds to the HTD 3M profile, the 477 mm length and the 3 mm pitch. If the old belt is worn or dirty, clean the back with a dry cloth and read the characters in good light; photograph the marking if any digits are faint.
Once you have the marking, match it against the drive data. The 477 3M SL 450 is a timing belt in the HTD series, with a 3 mm pitch and a 477 mm length. These three values, profile, pitch and length, are what you send to confirm the correct belt. If the marking is unreadable, measure the old belt and note the tooth profile and the number of teeth so the team can help identify the right part.
