What It Is

This is a replacement spindle assembly for 42" to 54" mower decks on Husqvarna, Craftsman, and some Poulan/Yard-Man tractors. It drives the mower blade from the deck pulley and is commonly needed when the blade wobbles, the spindle seizes, or the bearing fails.

Fitment & Compatibility

Deck size: Fits 42", 46", 48", and 54" stamped steel decks only—not fabricated decks.
Models it fits: Husqvarna YTH22V46, YTH24V48, YTA24V48, YTH2348, YTA18542; Craftsman YT3000, YS4500, YT4000. Also fits many Poulan and Yard-Man mowers with similar AYP/Electrolux decks.
OEM cross-references: 187292, 192870, 532187281, 567253301, 587819701, 587125401.
What to measure: Overall spindle height (approx. 4.5"–5") and pulley bolt pattern (3 holes on 2.5" circle). Verify your deck has a 5/8" hex shaft (common) and that the housing bolt pattern matches your deck’s mounting holes.
Check before buying: Count the number of spindle assemblies on your deck (usually 2–3). This is a 1-pack; if you need more than one, order multiple.

Key Things to Know

• Quality: Aftermarket part, solid for the price. Bearings are sealed and pre-greased. Some users report slightly shorter bearing life than OEM (2–3 seasons vs 4–5), but it’s a fraction of the OEM cost.
• Installation difficulty: Moderate. You’ll need a socket set, a jack or blocks to support the deck, and a torque wrench (tighten pulley nut to 30–40 ft-lbs). No special tools required.
• Common gotchas: The pulley may not come pre-installed—you’ll need to reuse your existing pulley or buy a separate one. Also, the spindle housing holes may not align perfectly on every deck; slight filing may be needed.
• Tip: Replace all spindles at once if one fails—the others are likely close to failing too, and you’ll save time.

Should You Buy It

Yes, if you have a compatible 42–54" stamped deck and want a budget-friendly replacement that works reliably for a few seasons. It’s ideal for DIY homeowners who don’t want to pay OEM prices. Skip it if you need a heavy-duty commercial spindle or if your deck uses an unusual shaft size or bolt pattern.
