Meet the REPLACEMENTKITS.COM Roto-Tiller Axle Seal 2pc Set—designed to restore reliable sealing and smooth operation for popular rototiller models. This kit fits a 1.000" shaft with a 2.000" bore and arrives as a two-piece assembly. For thorough coverage on some machines, you may need two sets (four seals total). Always verify size and fitment before purchasing to ensure a proper match for your equipment.

Fit and Compatibility

These seals are intended as a direct replacement for select tiller varieties, including Cub Cadet RT Series, Troy-Bilt Bronco and Super Bronco, and other brands that share the same transmission housing shape. The set aligns with transmission housing 919-04184A and related components, making it a practical option for machines with the common 1.000" shaft and 2.000" bore.

Size and Configuration

The kit is sized for a 1.000" shaft and a 2.000" bore. It ships as a 2-piece set; depending on your model, you may need two sets (four seals) for full coverage. Always confirm your size and fitment to avoid mismatches during installation.

Direct Replacement and Installation

As a direct replacement, these seals simplify maintenance by providing ready-to-install parts instead of sourcing from multiple suppliers. They are built for durability and can help streamline routine service or mid-season repairs when seals wear or leak. This kit is designed to replace 721-04232 on compatible units.

Engineered to withstand challenging conditions, the seals tolerate a broad temperature range from -40°F to 225°F (-40°C to 107°C). This range supports consistent sealing across seasonal shifts and field use, while maintaining structural integrity under normal operating loads.
