168825 - Miller Drive Pinion Gear 22T 24P

Restore Smooth Wire Feeding with the Miller 168825 Pinion

Is your wire feeder making grinding noises or struggling to push wire consistently? The issue might be buried deep in the drive mechanism. The Miller 168825 Drive Pinion is a critical replacement part that helps get your machine back to peak performance. This small but mighty gear is responsible for transferring power from your feeder's motor to the drive rolls that grip the wire. When the teeth on this gear become worn, stripped, or damaged, you'll experience erratic wire feeding, slipping, and frustrating arc instability that can ruin your welds.

Built from durable sintered metal, this 22-tooth gear is designed to handle the daily grind of a welding shop. It features a 24 pitch and a precise 0.376-inch bore hole, ensuring it fits perfectly onto the shaft of your compatible Miller equipment. Because it is a genuine Miller part, you don't have to worry about it not fitting or wearing out prematurely like some aftermarket knock-offs might. It is engineered to mesh perfectly with the other gears in your system, providing smooth, quiet operation.

Why Replace Your Drive Pinion?
Over time, metal-on-metal contact wears down even the toughest gears. If you notice that your wire speed fluctuates even when the dial hasn't moved, or if the motor sounds like it's spinning but the wire isn't moving, check your drive gears. A worn pinion can cause the drive rolls to hesitate, leading to burn-backs and uneven beads. Swapping out a damaged gear for a fresh Miller 168825 is a cost-effective repair that can save you from buying a whole new feeder assembly.

Don't let a small part cause big downtime. Keep your production line moving and your welds clean by maintaining your wire feeder's internal components. This package contains one drive pinion, ready to install. Verify your machine's manual or parts diagram to ensure this specific 22T, .376 bore gear is the right match for your model, and get back to welding with confidence.
