HD Switch Front Wheel Bearing Conversion Kit for Lawn Tractor 1-3/8" ID x 3/4" Axle — Sealed Bearings & Heat-Treated Hardware

This HD Switch conversion kit replaces worn front wheel bushings with sealed bearings and engineered components to stop axle wear and remove the need for frequent greasing.

If your lawn tractor or riding mower shows play in the front wheels or requires constant lubrication, this conversion kit provides a long-lasting retrofit that uses heat-treated hardware, premium hub caps, and a high-temperature synthetic grease formulation built into the assembly. The kit is designed to fit common spindle and hub dimensions (wheel I.D. 1 3/8" and axle O.D. 3/4") and is compatible with many Husqvarna, Craftsman, Poulan Pro, RedMax and related models that originally used bushing-style front wheel mounts.

Which machines will this HD Switch kit fit?

This kit was engineered to match the spindle and hub sizes used by a broad range of residential and light-commercial riding mowers and tractors. It replaces OE part numbers 536052602 and 536052702 and is compatible with multiple model families from major brands.

• Fits many Husqvarna/Garden Tractor models: GT, GTH, GTH/GT series listed in the product notes
• Also fits LGT, LGTH and TS series from related OEM lines
• Compatible with YT and YTH series garden tractors and similar models
• Wheel I.D. must be 1 3/8" and axle O.D. 3/4" for correct application

How does the conversion reduce maintenance and axle wear?

Replacing plain bushings with sealed bearings removes the metal-on-metal sliding contact that causes axle groove wear and wheel wobble. The kit uses bearings pre-tested for tolerance, a synthetic high-temp grease formulation, and protective hub caps to keep contaminants out.

• Sealed bearings keep lubrication inside and debris out for longer service life
• High-temperature synthetic grease rated to 400°F resists breakdown under heat
• Heat-treated hardware increases clamp integrity and reduces loosening
• Premium hub caps protect bearings from water, grass, and grit

What components are included and what quality standards were used?

HD Switch engineered the conversion using selected materials and manufacturing tolerances to meet or exceed the demands of yard equipment. The kit bundles bearings, hub caps, hardware, and lubrication chosen for durability and fitment accuracy.

• Precision sealed bearings matched to the specified hub and spindle dimensions
• Premium hub caps to shield the bearing seals from contamination
• Heat-treated bolts, nuts, and washers to maintain axle clamp forces
• Synthetic formula grease with wear-resistant additives included or pre-applied

How difficult is installation and what should I check before starting?

Installation typically requires basic hand tools, a press or arbor for bearing removal/installation, and mechanical familiarity. Inspect your spindle and hub dimensions, confirm OE part numbers, and have safety equipment on hand.

• Verify wheel I.D. (1 3/8") and axle O.D. (3/4") before ordering
• Remove old bushings and clean spindle bores; use a bearing press for best results
• Torque heat-treated hardware to manufacturer or kit-specified values
• Check wheel runout and bearing preload after fitting to ensure proper operation

Who is this for: The HD Switch Front Wheel Bushing to Bearing Conversion Kit is aimed at homeowners, landscapers, and small-fleet operators who want a durable, low-maintenance upgrade for tractors and mowers that originally used front wheel bushings. It suits anyone repairing worn front axles, eliminating grease points, or upgrading equipment longevity on compatible Husqvarna, Craftsman, Poulan Pro, RedMax and related models. Review the included model fit list and spindle/hub dimensions to confirm compatibility before purchase.
