This Dayco 3VX1120 is a cogged narrow V-belt in the 3VX profile with a length of 2844.8 mm. It is part of the Dayco cog wedged industrial belts series. The cogged construction is used on drives where a standard wrapped narrow V-belt may not provide the required flexibility or grip.

Cogged narrow V-belts are commonly found on industrial drives such as pumps, fans, compressors and other machinery where space is limited and speeds are moderate to high. The 3VX profile is a narrow cross-section, so it fits pulleys designed for 3VX belts. Before ordering, confirm that the drive uses a 3VX pulley groove and that the belt length matches the original. The 2844.8 mm length is the datum length for this belt.

To confirm fit, read the marking on the back of the old belt. Look for the profile (3VX) and the length (1120 or the equivalent in millimeters). If the old belt is worn or the marking is unreadable, measure the outside circumference with a flexible tape and compare it to the 2844.8 mm datum length. Also check the pulley grooves for wear and alignment, as these can affect belt life.

When replacing a belt, inspect the entire drive. Check sheave wear, misalignment and proper tension. If multiple belts are used on the same drive, replace them as a set to maintain even load sharing.
