Start by cleaning the back of the old belt and reading the full marking. You may see either 5121040 or the alias 12PK2640. Both identify this Dayco Poly-V belt: 12 ribs and a 42.16 mm width. Confirm the rib count and the effective length of 2641.6 mm against your drive layout before ordering.
If the marking is worn or unreadable, measure the effective length and count the ribs. This belt has 12 ribs and is 2641.6 mm long. A 12-rib belt will not fit a pulley set designed for a different rib count, so verify the number of grooves on the pulleys as well.
Send the part number from the old belt, or the numbers you can read, by WhatsApp or email. The team can confirm the Dayco 5121040 or help identify the correct belt for your application. Include the rib count and length if the marking is incomplete.
