The Dayco BP139 is a classical V-belt in the B profile. It measures 3606.8 mm in length, with a 17 mm top width, an 11 mm height and a 40° angle. This page covers how to match the marking on your old belt and what to send for a quote.
Start by reading the marking on the back of the belt you are replacing. A classical wrapped belt like this one is typically marked with its profile and length, so look for a B profile and the length value. If the belt is worn or the print has rubbed off, measure the top width and height with a caliper and compare them to the 17 mm and 11 mm dimensions above. The 40° angle is part of the profile and does not need to be measured separately.
Once you have the marking, confirm it against the Dayco BP139 data: B profile, 3606.8 mm length, 17 mm top width, 11 mm height, 40° angle. If the numbers match, you have the correct belt. If the marking is unclear, send a photo of the belt and the drive it runs on. Our team can help confirm the right belt or suggest an equivalent.
To request a quote, send the part number BP139 by WhatsApp or email. Include the quantity and any drive details you have, such as the pulley diameters or the application. If you are replacing more than one belt on the same drive, let us know so we can quote the full set.
