HD Switch Front Wheel Bushing-to-Bearing Conversion Kit 4-Pack — Sealed Bearings & Hi-Temp Grease for 1.375" Rim

HD Switch front wheel bushing-to-bearing conversion kit replaces worn bushings with sealed bearings and premium hub caps to restore smooth, reliable wheel rotation on compatible garden tractors and lawn mowers.

This 4-pack conversion kit is designed for owners of Husqvarna, Craftsman, Poulan, Jonsered, AYP and similar garden tractors who need a durable, easy-to-install upgrade for front wheels that originally used press-fit bushings. The kit includes sealed bearings, heat-treated fasteners, premium hub caps and high-temperature synthetic grease to reduce wear and improve wheel performance. It’s made to fit wheels with 1.375" rims and 0.750" axles and matches part numbers such as 532009040, 9040H, 532124959 and others.

Will this kit fit my tractor’s front wheels?

If your front wheels use a 1.375" rim and a 0.750" axle, this conversion kit is built to fit directly or with minimal adapter work. Confirm compatibility by checking the hub inner diameter and axle thickness against the listed dimensions and OEM part cross-references.

• Compatible with part references: 532009040, 9040H, 532124959, 5920H, 9040HR, 9040N
• Designed for 1.375" rim and 0.750" axle wheel setups
• Works for Husqvarna, Craftsman, Sears, Poulan, Jonsered, AYP models
• Measure hub bore and axle to confirm a snug bearing fit

How does converting bushings to bearings improve wheel performance?

Replacing worn bushings with sealed bearings reduces friction and heat, enabling smoother rotation and more consistent steering response. The sealed bearings keep contaminants out while the included high-temp synthetic grease protects internal surfaces under load and high-temperature conditions.

• Sealed bearings minimize dirt and moisture ingress for longer life
• Synthetic hi-temp grease rated to 400°F reduces wear under heavy use
• Heat-treated hardware resists deformation and ensures secure clamping
• Improved rolling efficiency cuts strain on spindles and steering linkages

What’s included and what makes this kit higher quality?

Each 4-pack contains a complete set of bearings, premium metal hub caps, heat-treated bolts and a tub of high-temperature synthetic grease. Components are selected for durability and easy installation so you get a long-lasting upgrade rather than a quick fix.

• Four sealed wheel bearings matched to common Husqvarna/Craftsman hubs
• Premium hub caps to protect bearings and improve dust sealing
• High-strength, heat-treated fasteners for reliable clamping force
• Synthetic hi-temp grease formulated with wear-resistant additives

Is installation difficult and what tools will I need?

Installation is straightforward for anyone comfortable with basic wheel and axle work. Typical steps include removing the wheel, extracting the old bushing, pressing or seating the new bearing, fitting the hub cap, and torquing hardware to spec.

• Basic hand tools: socket set, hammer, punch or bearing driver
• Press recommended for clean bearing installation but hand tools can work
• Follow torque values from your tractor’s service manual for axle nuts
• Grease bearings before installation using the supplied synthetic grease

Who this is for: This conversion kit is intended for homeowners, landscapers and small equipment mechanics who want to restore or upgrade front wheel performance on legacy lawn and garden tractors. If you own Husqvarna, Craftsman, Sears, Poulan, Jonsered or AYP machines with the specified wheel and axle sizes and want a durable, maintenance-friendly solution, this kit provides the parts and lubricant to get wheels rolling smoothly again without frequent rebuilds.
