The Dayco BP191 is a classical wrapped V-belt in a B profile. It measures 4927.6 mm in length, with a 17 mm top width, 11 mm height and a 40-degree angle. This page is for maintenance and purchasing staff who need to match a belt that is being replaced.

Start by reading the marking on the belt you are removing. If it shows BP191, this is the direct replacement. If the old belt is worn or the marking is gone, measure the outside length and compare it with the 4927.6 mm figure for this belt, then check the top width against 17 mm and the height against 11 mm. A B profile belt should sit correctly in the pulley groove; a belt that rides too high or too low in the groove is not the right match.

The BP191 is a classical wrapped V-belt, not a narrow wedge belt, cogged belt or banded belt. Confirm the drive uses a classical B section before ordering. Look at the pulleys for wear, oil or debris, and check that the sheave grooves are not worn beyond the point where a new belt sits too deep. If the drive runs more than one belt, replace the full set at the same time so the load is shared evenly.

For a quote, send the part number BP191 and the quantity you need by WhatsApp or email. If you are not certain the belt is a B profile or the length does not match, include the old belt's marking, the pulley diameters and the center distance. We can confirm the right belt or suggest an equivalent from what we carry.
