What It Is

This is a 2-pack of 197473 replacement pulleys designed for the mandrel or idler spindle assembly on select Craftsman and Husqvarna lawn tractors. It’s a direct swap for worn or damaged pulleys that drive the mower deck belt.

Fitment & Compatibility

• OEM cross-reference: Craftsman 197473, 195945; Husqvarna 532197473, 532195945; A riens 21546446.
• Fits models: Husqvarna YTH22V46, YTH18542, YTH20K46, YTH21K46, YTA18542; Craftsman YT3000, YT4000, YS4500.
• Check your deck size: Works with 42″ and 46″ decks on these series. Measure your existing pulley’s outside diameter (typically 4″ or 4.5″) and spindle bore (usually 1/2″ or 5/8″) to confirm.
• Aftermarket note: This is a non-OEM part. Verify that the pulley’s groove width matches your belt (common sizes: 1/2″ or 5/8″). If your original pulley has a stamped “197473” or “195945,” this will likely fit.

Key Things to Know

• Build quality: Most users report it’s a solid metal pulley, comparable to OEM. Some note the paint may chip faster, but function is unaffected.
• Installation: Requires basic hand tools (socket, wrench). You’ll need to remove a spindle bolt or idler arm bolt. No special puller needed, but a breaker bar helps if rusted.
• Common gotcha: The pulley’s center hole may be slightly tight on some spindles. Lightly sand or file the bore if needed—do not force it.
• Belt alignment: After installation, spin the pulley by hand to ensure it’s not wobbling. A warped pulley can cause premature belt wear.

Should You Buy It

If you need to replace a worn or noisy pulley on a compatible Husqvarna or Craftsman tractor (especially 42″ or 46″ decks), this 2-pack at $20.79 is a cost-effective fix. It’s not for heavy-duty commercial use, but for home lawn care it’s a solid value—just double-check your pulley diameter and bore before ordering.
