167761 - Miller 4-Roll Wire Drive Housing Kit

Restore Smooth Feeding with the Miller 167761 Kit

Is your Miller S-74 wire feeder struggling to push wire consistently? Are you experiencing slipping, stuttering, or the dreaded bird-nesting at the drive rolls? The problem might not be your settings—it could be a worn-out drive assembly. The Miller 167761 Drive Assembly, Wire S/L 4 Roll Kit is the genuine replacement part you need to get your industrial feeder back to peak performance. This isn't just a cosmetic part; it is the mechanical heart of your wire feeding system, responsible for gripping the wire and pushing it through the gun liner to the contact tip.

Why choose a 4-roll system? If you are welding all day, you know that traction is everything. A 4-roll drive system grips the wire at four points instead of two. This means you can get a solid grip with less crushing force. This is a game-changer if you run aluminum wire, which can easily get squashed and jam in the liner, or flux-cored wire, which is hollow and fragile. With this replacement assembly, you get the benefit of Miller's heavy-duty engineering, including easy-to-adjust tension arms that let you dial in the perfect pressure without tools.

This kit is designed as a direct replacement for the drive block on compatible Miller 70 Series feeders. Over time, the gears, bearings, and tensioners in your old assembly can wear out from dust, grit, and thousands of hours of use. Swapping in a fresh 167761 assembly eliminates the slop and play that causes erratic arcs. Don't let a bad feed mechanism ruin your welds or slow down production. Install the Miller 167761 and experience the smooth, reliable wire feeding that your machine was built to deliver.
