532194326 V-Groove Idler Pulley and 532194327 Flat Idler Pulley Kit Compatible with Husqvarna Riding Lawn Mowers, Replaces 280-6630, 194327, 705080, 13179, 705079, 194326, 280-6590, 194326

What It Is

This kit includes a V-groove idler pulley (532194326) and a flat idler pulley (532194327) that guide and tension the drive belt on Husqvarna riding lawn mowers. It’s designed for belt-driven mower decks where worn or seized pulleys cause belt slipping, noise, or poor cutting performance.

Fitment & Compatibility

Before buying, confirm:

• Deck size & model: Fits most Husqvarna 42-inch, 46-inch, 48-inch, 50-inch, and 54-inch stamped steel decks on select LGT, YTH, and GTH series riders (e.g., YTH22V46, LGT2654, GTH52K). Also compatible with some Poulan Pro, AYP, and Craftsman models using the same deck platform.
• OEM cross-references: Replaces Husqvarna 532194326, 532194327, 280-6590, 280-6630, 194326, 194327, 705079, 705080, and 13179.
• Physical check: Measure the existing pulley bore diameter (typically 1/2-inch or 5/8-inch) and overall outer diameter (usually 3.5 to 4 inches). This kit uses a 3.5-inch V-groove pulley and a 3.5-inch flat pulley with a 1/2-inch bore. If your deck uses a different bore size, this kit won’t fit.
• Belt width: Designed for 1/2-inch wide belts. Verify your belt width before purchase.

Key Things to Know

• Quality vs. OEM: Aftermarket pulleys are zinc-coated steel—durable and rust-resistant, but bearings may not last as long as genuine Husqvarna parts under heavy use.
• Installation difficulty: Moderate. Requires removing the deck, belt, and old pulleys (may need a puller or penetrating oil if seized). Basic hand tools and a socket set are sufficient.
• Common gotcha: The V-groove pulley orientation matters—the groove must face the belt. Installing backwards causes belt misalignment and rapid wear.
• Replace in pairs: If one pulley is worn, the other is likely close behind. Replacing both at once saves time and prevents future belt damage.

Should You Buy It

This kit is a smart, cost-effective choice for DIY owners replacing worn pulleys on common Husqvarna or compatible riding mowers. It’s not built for commercial duty, but for residential use at $16.99, it delivers reliable performance and easy fitment—just double-check your bore size and belt width first.
