What It Is

This is a 2-pack of spindle assembly kits designed to replace the rotating hub and bearing housing that drives the mower blade on Husqvarna and Craftsman lawn tractors. It fits 42" and 46" fabricated or stamped decks, commonly found on YTH, TY, and YT series models.

Fitment & Compatibility

Before buying, confirm your deck size (42" or 46") and check your existing spindle part number. This kit replaces OEM numbers 587819701, 187281, 532187292, 587820301, 587253301, 532192870, 587125401, and 192872. It fits models like Husqvarna YTH18542, YTH22V46, YTH20K46, TY3000, YT4000 and Craftsman equivalents. Measure the spindle bolt pattern (typically 3-bolt, 3.25" center-to-center) and shaft diameter (usually 1" or 7/8") to match your deck. Aftermarket, not OEM—verify pulley and blade compatibility separately.

Key Things to Know

• Quality concerns: With a 3.3-star rating from only 3 reviews, build quality is unproven. Some users report premature bearing wear or misalignment.
• Installation difficulty: Moderate. Requires removing the deck, belt, pulley, and old spindle. You’ll need a socket set, wrench, and possibly a puller for stuck spindles.
• Common gotchas: Pulley bolts may be reverse-threaded on some decks. Torque spindle bolts to spec (typically 30-40 ft-lbs). Use thread locker to prevent loosening.
• Pack contents: Includes two complete spindle assemblies with bearings and shaft—no pulley or blade included. Check if your existing pulley fits.

Should You Buy It

This is a budget-friendly option for DIYers who need two spindles at once and can handle moderate installation work. It’s best for older or less-used tractors where OEM cost isn’t justified, but be prepared for potentially shorter lifespan than genuine Husqvarna/Craftsman parts. If reliability is critical or your deck sees heavy use, spend more on OEM.
