The Dayco AP42 is a classical wrapped V-belt in the A profile, with a length of 1117.6 mm. When you need to match a belt on an existing drive, the marking on the old belt is the first thing to read. MR Industrial Accessories supplies this belt to maintenance, engineering and purchasing teams across the US, Canada, Mexico and South America.
The AP42 is built to the A profile: 13 mm top width, 8 mm height and a 40° angle. Its 1117.6 mm length makes it a direct reference for drives that call for this size. The classical wrapped construction is suited to standard industrial V-belt drives, and the part number is the key to confirming the correct replacement.
Start by reading the marking on the back of the old belt. Note the full part number, the profile letter and the length. If the marking is worn, measure the top width and the outside length, and check the pulley groove to confirm the profile. Send the part number and any photos to MR by WhatsApp or email, and the team will confirm the right belt or suggest an equivalent.
For drives with multiple belts, replace the full set at the same time so the load stays even across the grooves. Inspect the pulleys for wear, alignment and debris before installing the new belts. Keep the old belt as a reference until the drive is running correctly.
