2 Pack 197473 Spindle Pulley Replaces 532197473 Pulley Craftsman, Husqvarna 532195945 Spindle Pulley 21546446 for Husqvarna 42" 46" YTH22V46 YTH18542 YTH21K46, Craftsman YT3000 YT4000 Mowers

What It Is

This 2-pack of 197473 spindle pulleys replaces the OEM part on select Craftsman and Husqvarna lawn mower decks. They drive the mower blades via the belt, critical for cutting performance on 42" and 46" decks.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Fits 42" and 46" decks only. Common on Husqvarna YTH22V46, YTH18542, YTH21K46, and Craftsman YT3000, YT4000.
• OEM cross-reference: Replaces 532197473, 532195945, and 21546446. Not a direct OEM part—this is an aftermarket replacement.
• Measure your old pulley: Confirm outer diameter (usually ~4") and center hole size (typically 5/8" or 3/4"). Spindle shaft must match.

Check your mower’s model number (stamped under seat or on deck) to ensure deck size and spindle type align. If you have a different brand (e.g., John Deere, MTD), skip this.

Key Things to Know

• Quality vs OEM: Aftermarket pulleys may use lighter steel or less precise bearings. Expect 1-2 seasons of heavy use, not lifetime.
• Installation difficulty: Moderate. Requires removing deck, belt, and blade. You’ll need a socket set and possibly a puller for stuck pulleys.
• Common gotcha: The pulley’s center hole must match your spindle shaft’s diameter exactly—most common mismatch is 5/8" vs 3/4". Measure before ordering.
• 2-pack value: Cheaper per pulley than buying singles, but only useful if both pulleys need replacing.

Should You Buy It

Buy this if you have a 42" or 46" Craftsman or Husqvarna mower, need a budget-friendly replacement for a worn spindle pulley, and are comfortable with moderate DIY installation. Skip it if you want OEM longevity or have a different brand—then buy a verified OEM part for your specific model.
