2 Pack 587819701 Spindle Assembly with 532197473 Spindle Pulley and Idler Pulley 592855001 Belt 1/2x101 Replaces 532187281 587820301 187292 587253301 195945 for YT3000 YT4000 YTH18542 Mowers

What It Is

This 2-pack spindle assembly kit includes the 587819701 spindle, 532197473 spindle pulley, 592855001 belt (1/2x101), and an idler pulley. It’s designed for Husqvarna YT3000, YT4000, and YTH18542 series lawn tractors, replacing worn spindles and pulleys that drive the mower blades.

Fitment & Compatibility

• Check your deck size: Fits 42-inch and 46-inch cutting decks on Husqvarna and some Poulan, Craftsman, or McCulloch models.
• OEM cross-references: Replaces 532187281, 587820301, 187292, 587253301, and 195945. Verify your old part number matches.
• Belt spec: The included belt is 1/2-inch wide by 101 inches long. Measure your old belt length to confirm.
• Spindle bolt pattern: The spindle assembly uses a standard 3-bolt pattern (spacing ~3.5 inches center-to-center). Measure your deck’s mounting holes before buying.
• Not universal: Avoid if your mower uses a different spindle diameter or offset pulley design.

Key Things to Know

• Quality vs OEM: These are aftermarket replacements. They’re durable for residential use but may not hold up as long as OEM under heavy commercial mowing.
• Installation difficulty: Moderate. You’ll need a socket set, torque wrench (tighten spindle bolts to ~30-40 ft-lbs), and possibly a puller for old pulleys. Expect 1-2 hours per spindle.
• Common gotcha: The idler pulley may require a different belt routing than your original. Check your deck diagram or take a photo before disassembly.
• Includes everything: You get two spindles, two pulleys, and the belt—no extra parts needed for a full replacement.

Should You Buy It

Buy this if you have a Husqvarna YT3000/YT4000/YTH18542 with a worn spindle (noisy, wobbling, or seized blade) and want a cost-effective, complete kit that saves you from sourcing parts individually. Skip it if you need OEM durability for heavy commercial use or if your deck uses a different spindle bolt pattern.
