HD Switch Front Wheel Bearing Rebuild Kit, 2-Kit Pack — Garter Spring Seals & Bore-Sealant Coating

The HD Switch Front Wheel Bearing Rebuild Kit is a direct-fit OEM upgrade that replaces common Scag front wheel bearing assemblies with spring-loaded garter seals, upgraded bushings, and bore-sealant coating for long-lasting protection.

This two-kit package contains components engineered to restore wheel-end function and extend service life on compatible Scag equipment. Each rebuild kit includes cup-and-cone bearings, improved seals that use a garter spring to maintain consistent contact, and bushings with a bore-sealant finish. The design focuses on keeping out dirt, dust, and moisture while improving fit against imperfect bores.

How does this kit improve wheel bearing protection?

The kit’s spring-loaded garter seals apply constant radial pressure to the shaft for a tighter, more reliable seal than standard lip designs. A bore sealant coating on the inside of the seal compensates for small machining variances, reducing leakage paths.

• Garter spring maintains continuous seal contact
• Bore-sealant coating fills small surface imperfections
• Seals resist water, dust, and debris infiltration
• OEM-fit components simplify installation

What parts are included and how many kits will I receive?

This listing ships two complete rebuild kits—sufficient to service both front wheels or to keep a spare set on hand. Each kit contains matched cup-and-cone bearings, upgraded spring-loaded seals, and replacement bushings sized for the indicated Scag part numbers.

• (2) Upgraded spring-loaded seals per kit
• (2) Replacement bushings per kit
• Two complete kits included in the package

Will this fit my machine and how does it replace Scag part numbers?

The components are sized to replace several common Scag front wheel bearing part numbers listed in the product title. Match your current part numbers and dimensions to confirm compatibility before purchasing. The rebuild kit is designed as a direct OEM upgrade to the referenced Scag parts.

• Cross-replaces Scag: 482621, 482622, 43584, 482503, 457291, 483050
• Intended for front wheel bearing assemblies on compatible models
• Confirm by comparing part numbers or measuring existing bearings/seals
• Includes all internal wear components—no hub machining required

How difficult is installation and what tools are recommended?

Installation is straightforward for anyone familiar with wheel-end service. Basic mechanic tools plus a press or bearing driver kit speed the job and ensure correct seating of cups, cones, seals, and bushings.

• Common hand tools: sockets, wrenches, and a hammer
• Press or bearing driver for accurate cup and cone installation
• Grease and torque wrench for final assembly to spec
• Refer to machine service manual for torque values and procedures
