0460104880 - ESAB Left Drive Roll for PKB 250/400 Wire Feeders

Stop Fighting Your Wire Feeder

Is your ESAB PKB feeder slipping? Are you constantly adjusting the tension knob just to get the wire to move? It might be time to check your drive rolls. The ESAB Feed Wheel Left (0460104880) is the direct replacement part you need for your PKB 250 or PKB 400 wire feeder. When these wheels wear out, they lose their grip on the wire. This causes the wire to stutter or stop completely, usually right in the middle of a critical bead. Swapping out the old, worn-out wheel for this new one is the quickest way to get your machine running like new again.

This specific wheel is designed for the left side of the drive mechanism. It’s not a generic "one-size-fits-all" part; it’s made by ESAB specifically for these machines. That means you don't have to worry about it not fitting or stripping out after a week. It drops right in, locks in place, and grabs the wire firmly without crushing it. Good traction means consistent wire speed, and consistent wire speed means a smooth, buttery arc that makes you look good.

We know that downtime kills your paycheck. You don't have time to be taking the feeder apart every hour to clear a bird's nest or fix a jam. By keeping your feed wheels fresh, you eliminate one of the most common causes of MIG gun problems. If you see grooves worn into your old wheel, or if the teeth look rounded off, toss it and put this one in. It’s a cheap fix that saves you a ton of headache later.

Make sure you are ordering the correct side! This is the LEFT wheel. Check your manual or look at the diagram on your feeder door if you aren't sure. Keep your PKB 250 or 400 running smooth and keep the sparks flying with genuine ESAB parts.
