The Optibelt 3V 425 SK S=C Plus is a narrow wedge V-belt in the 3V profile with a length of 1079 mm. When the belt on the drive is worn or unreadable, the marking on the back of the old belt is the fastest way to confirm what you need. Read that marking before you order, and match the profile and length to this belt.
The back of a V-belt carries the profile and the length designation, and on this belt that reads 3V 425. The 3V profile tells you the cross-section family, and 425 is the length designation used with it. The length_mm value for this belt is 1079 mm, so the number on the back and the metric length are two ways of identifying the same belt.
Before ordering, inspect the drive. Check the sheave grooves for wear, confirm the belt sits correctly in the groove, and verify the belt path and tension. If the drive runs more than one belt, replace the full set together so the load stays evenly divided. A worn belt that still carries a readable marking gives you the cleanest starting point for a match.
Send the part number, the marking from the back of the old belt, and the quantity you need by WhatsApp or email. The team replies promptly and can help confirm the right belt for the drive. The same size is also listed under Stark 3V 425, Mitsuboshi 3V 425 and Dayco 3V 425.
