The Dayco 28480 is an automotive V-belt with a 22.35 mm top width and a 1219.2 mm effective length. Its 38-degree angle matches the groove geometry of the pulleys it is designed to run in. The alias 20A1220 identifies the same belt when you are reading a marking or a parts list.
Profile and length are the two dimensions that decide whether a belt will sit correctly in the drive. The 22.35 mm width and 38-degree angle place this belt in a specific pulley groove range, while the 1219.2 mm effective length is measured around the pulley path, not along the outside of the belt. A belt that is close but not exact in either dimension will not transmit load the way the drive was set up to.
When you are matching a belt already on the machine, read the marking on the back of the belt and compare it with the part number and the alias. If the old belt is worn, stretched or has lost its shape, the printed number is more reliable than a measurement taken from the used belt. Send the part number, the alias if you have it, and the drive it runs on, and we will confirm the belt or suggest an equivalent.
The Dayco 28480 is supplied as a single belt. On drives that use more than one belt in parallel, replacing the full set at the same time keeps the load shared evenly across the grooves. Inspect the pulleys for wear, alignment and debris at the same time, since a worn groove will shorten the life of any new belt.

Frequently asked questions
- What does the 22.35 mm width and 38-degree angle tell me?
- They describe the belt cross-section and the angle of its sides. The belt must sit in a pulley groove cut to match that profile so the sides grip the pulley and transmit load without slipping or sitting too deep.
- How is the 1219.2 mm length measured?
- It is the effective length, measured around the path the belt follows in the drive rather than along the outside face of the belt. Use the effective length when comparing this belt with another.
- What should I send to request a quote?
- Send the part number 28480, or the alias 20A1220, along with the drive it runs on. If you are replacing an existing belt, the marking on the back of that belt is the best reference.
