532194326 V-Groove Flat Idler Pulley Kit Replacement for Husqvarna Craftsman Poulan 194326 Fits YTH2246 YTH2454 YTH2042 CT126 CT154 CTH164T

What It Is

This is a V-groove flat idler pulley kit (OEM part 532194326) that routes and tensions the deck belt on select Husqvarna, Craftsman, and Poulan lawn tractors with 42-inch to 46-inch cutting decks. It replaces a worn or seized pulley that causes belt slippage, poor cutting, or belt breakage.

Fitment & Compatibility

Measure first: The pulley has a 4-inch outer diameter, a 5/8-inch bore, and uses a 3/8-inch hex bolt. Confirm your old pulley matches these dimensions.

Model fit: Directly fits many Craftsman (YTH2246, YTH2454, YTH2042, CT126, CT154, CTH164T) and Husqvarna/Poulan models with 42" or 46" decks. Verify your model number on the tractor’s data tag (usually under the seat or on the frame).

OEM vs aftermarket: This is an OEM-style replacement, not genuine OEM. It matches the original part dimensions but may use a slightly different bearing or metal finish. Always compare the new pulley’s shoulder height and groove profile to your old one.

Check the belt: This pulley works with most A-section V-belts (1/2 inch wide). If your belt is worn or wrong size, replace it at the same time.

Key Things to Know

• Installation difficulty: Easy to moderate (30-60 minutes). Requires basic hand tools (socket wrench, possibly a breaker bar). No special skills needed.
• Common gotcha: The bolt is often very tight from factory vibration. Use penetrating oil and a breaker bar to avoid stripping the bolt head.
• Quality note: The bearing is sealed, but the pulley is stamped steel. It will last 1-3 seasons under normal use. If you mow thick, wet grass or have heavy debris, expect shorter life.
• Always replace in pairs: If one idler pulley is failing, the other is likely close behind. Consider buying two and replacing both on the same deck.

Should You Buy It

If your tractor deck belt is slipping, squealing, or you see wobble in the idler pulley, this is a solid, low-cost fix. It’s not premium-grade, but for $10 and a simple swap, it’s the right choice for most homeowners. Skip it if you need a heavy-duty or commercial-grade pulley—look for a cast-iron or sealed-bearing option instead.
