This Dayco 3V 315 is a narrow wedge V-belt in the 3V profile with a length of 787.4 mm. The 3V profile and the 315 length are the two numbers that matter when you are matching a belt to a drive. The same size is also listed under Stark 3V 315, Mitsuboshi 3V 315 and Optibelt 3V 315.

Narrow wedge belts are identified by profile first, then length. The 3V profile sets the cross-section, and 787.4 mm is the datum length for this belt. When you read a drive, the sheave groove and the belt profile must agree, and the length must suit the center distance and take-up. If the old belt is worn or the marking is gone, measure the length and confirm the profile before ordering.

Replacement is straightforward once the profile and length are confirmed. Check the sheaves for wear, alignment and debris, and set tension to the drive manufacturer's specification. On multi-belt drives, belts run as a set, so replace all belts on the drive at the same time rather than one at a time. That keeps the load shared and avoids the new belt carrying more than its share.

To request a quote, send the part number 3V 315, the quantity, and the drive or equipment it fits.
