The Dayco BP142 is a classical wrapped V-belt in a B profile, with a length of 3683 mm, a top width of 17 mm, a height of 11 mm and a 40 degree angle. If you are replacing a belt on an existing drive, this page helps you confirm that the belt in your hand matches the BP142 before you request a quote.

Start with the belt you are removing. Read the marking on the back: it should show the part number BP142, or at least the B profile and the 3683 mm length. Measure the outside length if the marking is worn, and compare it with the 3683 mm figure. Check the cross section as well: a B profile belt has a 17 mm top width and an 11 mm height, and the 40 degree angle is the standard wedge shape for this construction. If those numbers line up, the BP142 is the correct size.

Also look at the drive itself. Confirm that the sheave grooves are clean and undamaged, and that the pulleys are aligned. A wrapped classical belt like this one is used on industrial drives where the belt runs in matched grooves, so a worn sheave can shorten belt life even when the size is right. If you are replacing more than one belt on a multi-belt drive, order the full set so the load is shared evenly.

When you send your request, include the part number BP142 and the quantity you need. If you are unsure whether this is the belt you are replacing, send a photo of the marking on the old belt and the drive arrangement. Our team can confirm the B profile and 3683 mm length, and help you identify the correct replacement.
