2 Pack 587819701 Spindle Assembly with 197473 Pulley 532196106 532177968 Pulley Replace 532187281 587820301 587253301 532187292 532192870 for Craftsman 42" Husqvarna YTH18542 YTH22V46 Decks

What It Is

This is a 2-pack of spindle assemblies (each includes a 197473 pulley) designed to replace the OEM pulleys and spindles on 42-inch Craftsman and Husqvarna mower decks. It’s for the blade drive system—each spindle mounts a blade and spins via the deck belt, so failing spindles cause vibration, uneven cut, or blade lockup.

Fitment & Compatibility

Before buying:

• Deck size: Only for 42-inch cutting decks. Not for 46-inch or wider models.
• Brands/models: Fits Craftsman 42" (e.g., YTH18542, YTH22V46) and Husqvarna YTH18542, YTH22V46. Also compatible with some Poulan, Husqvarna, and AYP decks using the same spindle pattern.
• OEM cross-references: Replaces 532187281, 587820301, 587253301, 532187292, 532192870. Does not replace 587819701 as a single unit—this is a 2-pack of that exact spindle.
• Measurements: Spindle shaft is 5/8" diameter, overall height ~4.5". Pulley is 3.5" OD, 5/8" bore, with a 1/2" belt groove. Verify your deck belt width (typically 1/2" or 5/8")—if your belt is wider, pulleys won’t match.
• Mounting: Uses 3-bolt pattern on 3.5" centers. Check your deck’s spindle bolt hole spacing before ordering.

Key Things to Know

• Quality: All-metal construction with sealed bearings. Heavier than some budget aftermarket spindles. Reviews note consistent balance and no wobble out of the box.
• Installation difficulty: Moderate. You need a socket set, jack stands (to lift deck), and penetrating oil for rusted bolts. Expect 30–60 minutes per spindle. Pulley is pre-installed—do not remove it unless replacing separately.
• Common gotchas: The pulley’s 1/2" belt groove may not fit decks using 5/8" belts (check your belt width). Also, the spindle shaft keyway is flat—if your blade uses a square key, you may need to file a notch. Spindle bearings are sealed but not serviceable; replace as a unit when worn.
• Warranty: Usually 90-day limited. Confirm with seller.

Should You Buy It

Buy this if you have a 42" Craftsman or Husqvarna deck with worn spindles (grinding noise, blade wobble, or uneven cut) and want a direct-fit, all-metal replacement at a fair price. Avoid if your deck uses a 5/8" belt, square-key blades, or if you only need one spindle—this is a 2-pack only.
