0334328002 - ESAB 19-Tooth Drive Pulley Replacement

Restore Smooth Wire Feeding with Genuine ESAB Parts

Is your ESAB wire feeder making grinding noises or feeding wire inconsistently? The issue might be buried deep inside the drive mechanism. The ESAB Toothed Pulley Z=19 (0334328002) is a genuine replacement part that helps get your machine back to running like new. This small but mighty pulley is responsible for transferring power from the motor to the drive rolls that push the welding wire out to your gun. If the teeth on your old pulley are worn down, stripped, or damaged, the internal belt can slip, causing the wire to stutter, stop, or feed at uneven speeds—ruining your welds and your patience.

Welding is all about consistency, and a smooth wire feed is the foundation of a good MIG weld. When you pull the trigger, you expect the wire to come out at the exact speed you set. This OEM pulley ensures that mechanical connection is solid. Because it has exactly 19 teeth (Z=19), it maintains the correct gear ratio intended by the factory, ensuring your wire feed speed dial actually corresponds to the wire output. Don't settle for "close enough" aftermarket parts that might not fit the shaft perfectly or might chew up your drive belts. This authentic ESAB part drops right in, fitting the shaft securely and meshing perfectly with the drive belt.

Replacing internal drive components can seem daunting, but it is often necessary maintenance for older machines that see heavy use. If you are already opening up the case to replace a broken belt or service the motor, checking the condition of the pulleys is a smart move. If the teeth look sharp or jagged instead of smooth and uniform, or if you see metal shavings, it's time to swap it out. Keeping a spare 0334328002 pulley in your maintenance kit can save you days of downtime when a breakdown occurs. Trust in genuine ESAB parts to keep your fabrication shop running smoothly and your arcs stable.
