42" 46" 48" 54" Mower Deck 187292 Spindle with Pulley 195945 Fit for Husqvarna Z254 YTH22v46 YTH24v48 Craftsman YT3000 YS4500 YT4000 Lawn Mower Replaces OEM Spindle 192870 587819701 532187281 2 Pack

What It Is

This is a replacement mower deck spindle assembly with a pre-installed pulley, designed to mount the blade and transfer belt power on 42–54 inch cutting decks. It’s a direct-fit, aftermarket part for Husqvarna, Craftsman, and similar residential zero-turn and lawn tractors, sold as a 2-pack.

Fitment & Compatibility

Before buying, measure your existing spindle’s shaft diameter (typically 5/8” or 3/4”) and overall height. This spindle (OEM cross-reference 192870, 587819701, 532187281) fits Husqvarna Z254, YTH22v46, YTH24v48, and Craftsman YT3000, YS4500, YT4000 models with 42”, 46”, 48”, or 54” decks. Check your deck’s spindle spacing—some decks use different bolt patterns. Confirm your pulley diameter matches your belt path (common sizes: 3.5” or 4”). If your deck uses a stamped steel housing vs. fabricated, verify the mounting flange thickness.

Key Things to Know

• Quality: Aftermarket steel spindle with sealed bearings; typically matches OEM durability, but inspect the pulley for wobble before install.
• Installation: Moderate difficulty—requires removing the deck, blade, and belt. Use a torque wrench (usually 45-55 ft-lbs for spindle bolts). Replace the belt if worn.
• Gotchas: The pulley may use a different keyway or set screw than OEM—check your old pulley’s retention method. Some decks need a spindle puller if rusted.
• 2-Pack value: Often cheaper than buying singles, but verify both spindles are identical—some decks use left/right specific parts.

Should You Buy It

This is a solid, cost-effective choice if you’re replacing one or both spindles on a Husqvarna or Craftsman tractor with a 42–54” deck and want a drop-in fix without paying OEM prices. It’s best for DIYers comfortable with basic deck removal and bolt torque specs. Avoid if your deck requires a specific OEM-only spindle (e.g., with eccentric adjustment or unique bearing spacing).
