HD Switch Front Wheel Bearing Conversion Kit 4-Pack — 1.375" Rim / 0.750" Axle, Pre-Greased Sealed Bearings

HD Switch 4-pack front wheel bushing-to-bearing conversion kit replaces sleeve bushings with grease-packed bearings and reinforced hub caps to restore smooth, long-lasting wheel rotation on compatible Husqvarna and garden tractors.

This conversion kit is designed to upgrade front wheel assemblies on select Husqvarna, Craftsman, Poulan, Jonsered and AYP lawn and garden tractors. Instead of relying on ordinary sleeve bushings, the kit provides pre-greased bearings, heat-treated fasteners and robust hub caps sized for wheels with a 1.375" rim and a 0.750" axle. It’s a practical repair or performance improvement when wheels feel rough, bind, or require frequent lubrication.

How does this kit improve wheel performance?

Swapping sleeve bushings for sealed bearings reduces friction, improves wheel tracking, and minimizes heat buildup during operation. The included high-temperature synthetic grease and wear-resistant additives help the bearings run smoothly for longer intervals between services.

• Pre-greased sealed bearings for immediate installation
• Heat-treated bolts and washers for reliable clamping
• Hub caps to protect bearings from dirt and moisture
• Fits wheels with 1.375" rim and 0.750" axle dimensions

What’s included and how easy is installation?

The package contains four complete bearing conversion sets: bearings, synthetic grease, reinforced hub caps and hardened hardware. Basic hand tools are usually sufficient, and the kit is made to replace the factory bushings without specialized presses on many models.

• Four bearing assemblies with grease already applied
• Four hub caps to seat over the bearings
• Heat-treated bolts and secure washers
• Step-by-step fitment for specified mower models

Which mower models and wheel sizes are compatible?

This conversion kit is tailored for front wheels originally equipped with 1.375" rim and 0.750" axle specifications and lists fitment for a range of Husqvarna, AYP and related machines. Always confirm dimensions on your tractor’s front wheel assembly before ordering to ensure proper fit.

• Compatible with Husqvarna part numbers like 532009040, 532124959
• Fits model references such as 9040H, 5920H, 9040HR, 9040N
• Also suitable for Craftsman, Poulan, Jonsered and AYP tractors that match the size
• Verify wheel rim (1.375") and axle (0.750") measurements prior to installation

How does the grease and hardware extend service life?

The kit includes a high-temperature synthetic grease formulated to hold up under typical lawn tractor heat and load, reducing wear on bearing surfaces. Heat-treated fasteners and reinforced hub caps maintain correct preload on the bearing, preventing loosening or premature failure from normal vibration and moisture exposure.

• Synthetic hi-temp grease rated for up to 400°F for stable lubrication
• Wear-resistant additives in the grease reduce metal-to-metal wear
• Heat-treated bolts resist stretching and maintain clamping force
• Hub caps shield bearings from grass, dirt and splashing water

Who is this for: This HD Switch 4-pack is aimed at owners and technicians of lawn and garden tractors who want a durable, service-reducing upgrade for rough or frequently serviced front wheels. It’s suited for DIYers comfortable with basic mechanical work, landscapers maintaining multiple machines, and anyone seeking a cost-effective way to restore smooth steering and reduce downtime on compatible Husqvarna, Craftsman, Poulan, Jonsered and AYP tractors.
