The Dayco 3V 1120 is a narrow wedge V-belt in the 3V profile with a length of 2844.8 mm. It is a common size on industrial drives where a worn belt is only part of the problem. Before fitting a new belt, inspect the drive so the replacement is not damaged by the same conditions that took out the old one.
Check the sheaves first. Look for worn grooves, a polished or dished contact face, and any burrs or rust that will shave the belt. Misalignment between sheaves is a frequent cause of short belt life, so confirm the sheaves run true to each other before the belt goes on. A sheave that has worn out of profile will not hold a new 3V belt correctly, no matter how well the belt is made.
Then check the rest of the drive. Confirm the sheave grooves match the 3V profile and that the take-up has enough travel to tension the belt properly. Spin the driven equipment by hand where it is safe to do so and listen for bearing noise or binding. If the drive runs more than one belt, replace the full set at the same time so the load is shared evenly.
The same size is also listed under Stark 3V 1120, Mitsuboshi 3V 1120 and Optibelt 3V 1120. Send the part number, the quantity and the drive details to MR by WhatsApp or email and the team will reply promptly, confirming the belt or suggesting an equivalent.
