When replacing a double-sided timing belt, start by reading the marking on the back of the old belt. This Optibelt Omega belt is identified as D5M 665 (HTD), with a length of 665 mm. Confirm those characters match before you request a quote.
The part number on the belt is the most direct match you have. If the old belt is worn or the print is faint, compare the profile and the length: this belt is a double-sided timing belt in the D5M profile with a 665 mm length. The Optibelt Omega series is what we carry under that part number.
A double-sided timing belt drives from both faces, so it is used where the belt must turn more than one driven component from opposite sides. When you inspect the drive, check both faces for cracking, exposed cord or missing teeth, and confirm the pulleys are clean and aligned. If the belt being replaced is marked D5M 665 (HTD), this is the same size to specify.
