The Dayco 2B17305 is a banded V-belt built for drives that need two V-belts to work as one. Its 28.7 mm width and 40° angle define how it sits in the pulley grooves, while the 774.7 mm effective length tells you where it will run in the drive. Use these three figures to confirm the belt matches your existing setup before you request a quote.

The 2B profile means two V-belt sections joined by a tie band. That construction keeps the sections aligned and helps control vibration on drives where single belts would slap or flip. The 28.7 mm width is the total across the banded assembly, so measure your pulley grooves to confirm they accept this profile. The 40° angle is the standard wedge angle for this belt type and must match the groove angle of your pulleys.

The 774.7 mm effective length is measured around the belt's pitch line, not the outside circumference. When you compare it to a worn belt, remember that old belts can stretch and give a false reading. Check the drive for groove wear, misalignment, and damaged sheaves before installing a replacement. If the drive runs multiple banded belts, replace them as a set to keep tension even across the grooves.

To request a quote, send the part number 2B17305 and the quantity you need. If you are unsure this is the correct belt, include the width and length from your old belt's back marking, plus the drive make and model. Our team will confirm the profile and length or suggest an equivalent.
