The Dayco AP173 is a classical V-belt in the A profile, with a length of 4445 mm, a top width of 13 mm, a height of 8 mm and a 40° angle. This page gives you the dimensions and the steps to match it to the belt you are replacing. We carry this belt and quote by part number.

To match the belt being replaced, start with the marking on the back of the old belt. Confirm the profile is A and the length is 4445 mm. Then check the top width, 13 mm, and the height, 8 mm, against the old belt. The angle is 40°. If the old belt is worn or the marking is unreadable, measure the outside length and compare it to 4445 mm.

A classical V-belt runs in a matched groove, so the 13 mm top width and 8 mm height need to sit correctly in the pulley. A belt that is too wide or too tall will not seat, and one that is too narrow will slip. The 40° angle is the included angle of the belt cross-section. When you replace a belt, inspect the pulleys for wear and check the alignment of the drive before installing the new belt.

If you are replacing more than one belt on a drive, order the same part number for each position and replace them as a set. Send the part number AP173, the quantity, and the drive or equipment reference by WhatsApp or email. Our team replies promptly and can confirm the right belt or suggest an equivalent.
