It combines hardened cup-and-cone bearings with upgraded spring-loaded seals and a bore-focused sealant coating to block grit, moisture and lawn debris. The package contains everything needed for a single-side rebuild: two bearings (cup and cone), two upgraded seals, and two bushings—plus a spacer to set correct preload and alignment.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit improve wheel protection compared to stock parts?\u003c\/h3\u003e\n\u003cp\u003eThe key upgrade is the spring-loaded seal and bore sealant coating that compensate for casting irregularities and maintain contact across the sealing surface. That reduces contaminant ingress which is the main cause of premature bearing failure in turf applications. Hardened bearing races and precision-fit bushings also help the hub resist wear under load.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSpring-loaded seals maintain consistent pressure against the bore.\u003c\/li\u003e\n  \u003cli\u003eBore sealant coating fills small casting gaps for a tighter seal.\u003c\/li\u003e\n  \u003cli\u003ePrecision bushings reduce lateral play and improve bearing life.\u003c\/li\u003e\n  \u003cli\u003eHardened cup\/cone bearings resist abrasion from grit and moisture.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich mower models and part numbers does this rebuild kit fit?\u003c\/h3\u003e\n\u003cp\u003eThis kit is designed to be compatible with a range of Scag front wheel assemblies and common SM-series zero-turn hubs. It lists direct compatibility with OEM references and typical Turf Tiger configurations used by landscapers. Always verify part numbers against your machine’s service manual or current hub casting to ensure correct fit.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFits Scag part numbers: 482622, 482621, 482503, 457291, 483050.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Turf Tiger and SMST, SMT, SMTC, SMWC series front hubs.\u003c\/li\u003e\n  \u003cli\u003eIncludes spacer and bushings sized to original OEM specifications.\u003c\/li\u003e\n  \u003cli\u003eSold as a one-kit solution for one wheel rebuild (two bearings, seals, bushings).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat tools and steps are needed to install the kit?\u003c\/h3\u003e\n\u003cp\u003eInstallation requires basic shop tools and a press or bearing driver to remove old bearings and install new components without damage. Clean the hub bore thoroughly, apply the supplied bore sealant coating where needed, press in new bearings and bushings, fit the seals, and set the spacer to the OEM preload spec. If you don’t have a press, many lawn equipment shops will perform the service quickly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTools: bearing press or driver set, torque wrench, hub puller, cleaning solvent.\u003c\/li\u003e\n  \u003cli\u003ePrep: remove wheel and hub, clean bore, inspect for deep scoring.\u003c\/li\u003e\n  \u003cli\u003eInstall: press bearings\/bushings squarely, apply sealant coating, fit seals.\u003c\/li\u003e\n  \u003cli\u003eFinish: set spacer\/preload, reassemble and torque to manufacturer spec.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Landscapers, small commercial crews and owner-operators who maintain Scag Turf Tiger and SM-series mowers and want a durable, OEM-upgrade solution to extend wheel service life. It’s ideal for anyone dealing with muddy or dusty conditions where stock seals fail early, and for shops offering preventive maintenance packages. This kit lets you restore hub performance with parts engineered to close sealing gaps, reduce downtime and save on repeated replacements.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this kit a full replacement for one wheel hub?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
