Eureka/Sanitaire Commercial Upright Front Wheel - SC-4570

Part 39173A119N is the front wheel built for Sanitaire's SC-4570 commercial upright and a wide span of Eureka and Sanitaire commercial uprights, including 2961AVZ, 2991AVZ, 2993AV, 2999AVZ, 4393A, 4458A, 4459AS, 4463AV, 4464AT, 4467AV, 4468A, 4469AT, 4684AT, 4684B, 4685AT, 4686ATV, 4687AT, 4688ATV, 4689ATV, 4696AV, 4870BT, C4571A, C5712A, C5712A1, SC5713B, SC5713D, SC5745B, SC5815E, SC5845B, and SC5845D, plus the GE-Walmart GE5500.

A commercial upright puts far more hours on its front wheels than a residential machine ever does, rolling over thresholds, floor mats, and rough transitions dozens of times a shift. Once a wheel flattens on one side or cracks at the hub, the machine starts pulling to one side and takes noticeably more effort to push, and a hard plastic wheel with a flat spot can scuff or mark hard flooring on every pass even while the rest of the machine still runs fine.

• Part: 39173A119N
• Position: front
• Fits: Sanitaire SC-4570 and Eureka/Sanitaire commercial uprights including 2961AVZ, 4463AV, 4684AT, C5712A, SC5845D, and GE-Walmart GE5500

Because one wheel part spans such a wide range of model numbers, match the exact model stamped on the unit's data plate before you order rather than assuming any commercial Sanitaire or Eureka upright takes it. Swapping the wheel is a direct exchange at the axle, and it is worth checking the rear wheels for wear at the same time, since they see similar mileage, and replacing a worn set together saves a second teardown a few months later.
