2 Pack 587819701 Spindle Assembly Kit with 197473 Pulley 592855001 Belt Replaces 187281 532187292 587820301 587253301 532192870 21549012 for Craftsman 42 YT3000, Husqvarna 42 YTH18542 Tractors

What It Is

This is a 2-pack spindle assembly kit for 42-inch cutting decks, including pre-assembled spindles (with bearings and housings), pulleys, and a drive belt. It’s designed for Craftsman and Husqvarna lawn tractors with 42” decks, commonly used on the Craftsman YT3000 and Husqvarna YTH18542.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: This kit fits only 42-inch decks. Measure your deck width or check the model tag.
• Tractor model: Works with Craftsman YT3000, Husqvarna YTH18542, and similar 42” deck tractors. Cross-reference your OEM part numbers: replaces Craftsman 187281, 532187292, 587820301, 587253301, 532192870, and Husqvarna 21549012.
• Belt included: The 592855001 belt is included—verify your tractor uses this belt length (typically 92.5” for 42” decks). If your deck uses a different belt, you’ll need to buy separately.

Key Things to Know

• Build quality: Aftermarket kit, but bearings are pre-lubricated and sealed. Expect decent durability for residential use, but not commercial-grade.
• Installation difficulty: Moderate. You’ll need a socket set, jack, and possibly a puller for stubborn old spindles. Plan 1–2 hours.
• Common gotchas: The pulley hole pattern may not align perfectly with all OEM decks—check bolt spacing (typically 3-bolt pattern on 4” centers). Also, the belt routing is critical; consult your deck diagram to avoid premature wear.
• Pack contents: Two spindles (each with housing, bearings, and pulley), one belt, and mounting hardware. No blades included—buy separately if needed.

Should You Buy It

If you have a 42” Craftsman or Husqvarna tractor with worn or noisy spindles and need a budget-friendly replacement that includes a belt, this kit is a solid value. It’s not for heavy commercial use, but for residential mowing, it’ll restore smooth cutting. Skip it if your deck is larger or your tractor uses a different spindle bolt pattern.
