8TEN Deck Blade Spindle Kit for AYP Husqvarna Poulan YTH22V46 YTH21K46 YTH20K46 46-Inch 532403107 532187292 532187281

What It Is

The 8TEN Deck Blade Spindle Kit replaces the factory spindle assembly on 46-inch AYP (American Yard Products) mower decks used by Husqvarna, Poulan, and Craftsman. It houses the blade mounting pulley and bearings that spin the blades—essential for cutting performance and vibration control.

Fitment & Compatibility

Check these before buying:

• Deck size: Only fits 46-inch cutting decks (not 42-inch or 54-inch).
• Models: Direct replacement for Husqvarna YTH22V46, YTH21K46, YTH20K46, plus many Poulan and Craftsman models with 46-inch AYP decks.
• OEM cross-reference: Replaces Husqvarna/YP parts 532403107, 532187292, and 532187281.
• Measurements: Verify spindle shaft diameter (typically 5/8-inch) and bolt pattern (three-bolt flange, 3-inch center-to-center). Measure your old spindle to confirm.
• Quantity note: Kit includes one spindle assembly. Most 46-inch decks use two or three spindles—buy enough for a full replacement.

Key Things to Know

• Quality: 8TEN is an aftermarket brand. Users report good bearing quality and steel housing, but check for any casting flash before installation.
• Installation difficulty: Moderate. Requires removing the blade, pulley, and belt, then unbolting the spindle from the deck. A socket set and torque wrench (specs: 30-40 ft-lbs) are needed.
• Common gotcha: The pulley may have a different offset than OEM—compare stack height (pulley to mounting flange) to avoid belt misalignment. Some units need the old pulley reused.
• Lubrication: Spindle bearings are sealed; no greasing needed. If you see a grease fitting, it’s a different model—return it.

Should You Buy It

If your 46-inch Husqvarna or Poulan deck has a worn, noisy, or wobbling spindle, this 8TEN kit is a solid, cost-effective replacement. It fits the major AYP models and carries a good user rating. Just confirm your deck’s spindle count and belt alignment before ordering—it’s not a universal fit.
