Husqvarna Part Number 532403087 Spindle Asm.-LH

What It Is

The Husqvarna 532403087 Spindle Asm.-LH is the left-hand blade spindle assembly for select Husqvarna and compatible zero-turn and riding lawn mowers. It houses the bearings and shaft that drive the cutting blade, and is a direct OEM replacement for worn or damaged spindles.

Fitment & Compatibility

• Check your model: This spindle fits specific Husqvarna Z200, Z400, Z500, and some YTH and TS series mowers (e.g., Z242F, Z254, YTH24V48). Always verify with your model and serial number.
• OEM vs aftermarket: This is a genuine Husqvarna part, not an aftermarket copy. It matches original specs for bolt pattern, shaft length, and pulley fit.
• Measure before buying: Confirm the spindle mounting bolt pattern (typically 3- or 4-hole) and shaft diameter (usually 5/8" or 3/4"). Measure your old spindle or consult your deck diagram.
• Left-hand only: This is the LH (left side) spindle. The right-hand spindle is a separate part (532403088). Do not mix them.

Key Things to Know

• Quality: OEM bearings and steel housing are durable; expect 2-4 seasons of normal residential use. Grease fittings allow periodic lubrication to extend life.
• Installation difficulty: Moderate. Requires removing the deck, belt, pulley, and blade. Basic hand tools and a torque wrench recommended (blade bolt torque ~50-70 ft-lb).
• Common gotcha: The spindle pulley may need to be reused or replaced separately. Check your pulley condition before ordering.
• Warranty: Husqvarna covers OEM parts for 90 days; keep your receipt and note the installation date.

Should You Buy It

If you have a compatible Husqvarna mower and need a reliable, direct-fit left-hand spindle, this OEM part is a solid choice. It’s cost-effective for DIY repairs and avoids the fitment guesswork of generic spindles. Not ideal for commercial use or non-Husqvarna decks—verify compatibility first.
