187292 587819701 Spindle Assembly with 195945 Pulley for 42" 46" 48" 54" Mower Decks Fit for Husqvarna YTH22V46 YTH24V48 YTH24k54, Craftsman YS4500, YT4000, Replaces OEM 532187292 587819701

What It Is

This is a complete spindle assembly with a pre-installed 195945 pulley, designed to drive the mower blades on 42", 46", 48", and 54" mower decks. It’s intended for residential zero-turn and lawn tractors from Husqvarna and Craftsman, replacing worn or failed spindles that cause blade wobble or cutting unevenness.

Fitment & Compatibility

• Deck sizes: 42", 46", 48", 54" (measure your deck width and spindle-to-spindle spacing to confirm).
• Models: Fits Husqvarna YTH22V46, YTH24V48, YTH24k54, Craftsman YS4500, YT4000, and many others using the OEM 532187292 or 587819701 spindle.
• OEM vs aftermarket: This is a direct replacement for OEM part numbers 532187292 and 587819701. Check your existing spindle’s part number stamped on the housing.
• Measurements: Spindle shaft diameter is 5/8" (common for these decks). Overall height and bolt pattern must match your deck – measure center-to-center of mounting holes (typically 3" or 4" spacing). Pulley is 4.5" OD with a 5/8" bore and keyway.
• Key check: Ensure your deck uses a single-bolt blade retention (most do). If your blades use a shoulder bolt, this spindle will not fit.

Key Things to Know

• Installation difficulty: Moderate – requires removing the deck, belt, and blade. Basic hand tools (wrenches, socket set) and a jack or blocks to support the deck. Allow 45–60 minutes per spindle.
• Quality: Aftermarket spindle with sealed bearings. Most users report it’s as durable as OEM for residential use. Not recommended for heavy commercial mowing (bearings may wear faster under constant high-load use).
• Gotchas: The pulley is pressed on and not user-serviceable. If the pulley fails, you must replace the whole assembly. Also, check belt alignment after installation – slight shimming may be needed on some decks.
• Includes: Spindle housing, shaft, bearings, pulley, and mounting hardware (bolts, washers). Blade and belt sold separately.

Should You Buy It

Buy this if you need a drop-in replacement for a worn spindle on a Husqvarna or Craftsman lawn tractor with a 42"–54" deck and want to avoid paying OEM prices ($50–$80). It’s a solid value for residential mowers, but skip it if you’re running a commercial operation or need a serviceable spindle (bearings cannot be replaced individually).
