187292 192870 Spindle, for Husqvarna 532187281 532192870 532187292, for Craftsman 42" 46" Deck, for Husqvarna YTH22V46 YTH22V42 for Craftsman YS4500 YT4000, with 195945 Pulley, 2pc

What It Is

This is a replacement spindle assembly (with pulley) for 42-inch and 46-inch cutting decks on Husqvarna and Craftsman lawn tractors. It drives the blade, and this kit includes the spindle housing, bearings, and a 195945 pulley—saving you from buying parts separately.

Fitment & Compatibility

Before buying, check three things:

• Deck size & model: Fits 42" and 46" decks on Husqvarna YTH22V46, YTH22V42 and Craftsman YS4500, YT4000. Also works on many other Husqvarna/Craftsman models with those deck sizes.
• OEM cross-reference: Replaces Husqvarna OEM 532187281, 532192870, 532187292 and Craftsman 187292, 192870. If your original spindle has one of these numbers, this is a direct drop-in.
• Measure the pulley: The included 195945 pulley is 4.5" diameter with a 5/8" bore and 3/8" keyway. Confirm your deck pulley matches—some older decks use a different pulley size.
• Two-piece design: This is a two-piece spindle (housing + pulley). If your original is a single-piece unit, you’ll need to swap the pulley over or verify this assembly fits your deck’s bolt pattern.

Key Things to Know

• Quality: Aftermarket, but well-reviewed (4.5 stars, 84 reviews). Users report it matches OEM fit and lasts as long as factory parts.
• Installation difficulty: Moderate. You’ll need a socket set, a jack to lift the mower, and a puller to remove the old spindle from the deck. Expect 30–60 minutes per spindle.
• Common gotcha: The pulley nut can be stubborn—use penetrating oil and an impact wrench if available. Also, check blade alignment after installation; a bent deck shell can cause wobble even with a new spindle.
• Includes hardware: Kit comes with the pulley, spindle assembly, and necessary bolts. No need to chase extra parts.

Should You Buy It

If you need to replace a worn or noisy spindle on a 42" or 46" Husqvarna or Craftsman deck, this is a solid, cost-effective choice. It’s cheaper than OEM but fits and performs reliably for DIY repairs. Not for commercial use or odd-size decks—stick with OEM if you need exact factory specs.
