2Pack 532194326 194326 V-Groove Idler Pulley Compatible with Craftsman Husqvarna AYP YT3000 YET4000 4500 GT6000 YTH21K46 Lawn Mower, Including 2 Screws

What It Is

This is a 2-pack of V-groove idler pulleys (OEM part 532194326 / 194326) designed to tension and guide the drive belt on select Craftsman, Husqvarna, and AYP lawn tractors. It’s a common replacement part for the deck belt idler arm on 42–54 inch cutting decks.

Fitment & Compatibility

Before buying, verify these three things:

• Model number – Fits tractors like Craftsman YT3000, YET4000, 4500, GT6000, YTH21K46, and Husqvarna/AYP equivalents with 42–54 inch decks. Check your mower’s model tag (under seat or on frame) against the part number 532194326.
• Pulley dimensions – This pulley has a 4.0 inch outer diameter, 0.625 inch inner bearing bore, and a V-groove for standard deck belts. Measure your old pulley to confirm match.
• Screws included – Two 5/16-18 x 1 inch hex bolts are included, but verify thread pitch and length against your existing hardware. If your spindle uses a shoulder bolt or different thread, you’ll need separate fasteners.

Key Things to Know

• Quality – Aftermarket replacement, not OEM. Users report it’s durable and runs true for the price, but bearing life may be shorter than original (typically 2–3 seasons vs. 4–5 for OEM).
• Installation difficulty – Easy. Remove the belt tension, swap the old pulley, and re-tension. No special tools needed beyond a socket wrench.
• Common gotcha – The included screws may be slightly too long for some decks; check clearance against the deck housing. If they bottom out, use a washer or shorter bolt.
• Double-check belt routing – A misrouted belt can cause premature pulley wear or belt slip. Refer to your mower’s deck diagram.

Should You Buy It

Buy this if you need a quick, budget-friendly fix for a noisy or seized idler pulley on a Craftsman/Husqvarna tractor deck and you’re comfortable with basic wrenching. It’s a solid value for the price, but if you want maximum longevity or an exact OEM match, spend more on a genuine Husqvarna/Craftsman pulley.
