What It Is

This is a 3-pack of idler pulleys (OEM part numbers 532196106 and 532197379) that route and tension the deck belt on zero-turn and lawn tractors. Designed for 42" to 54" cutting decks on Craftsman, Husqvarna, and compatible models.

Fitment & Compatibility

Before buying, check three things:

• Deck size: Fits 42", 46", 48", and 54" decks – but verify your specific model’s deck width in the owner’s manual.
• Model strings: Direct replacement for Craftsman 196106 and 197379, and fits Husqvarna Z254f, Z254, YTH22v46, LGT2654, RZ5424, YTH2348, YTH24v48, YTH24k48, RZ5426, plus Craftsman 54" and 42" mowers. Not universal – cross-reference your model number.
• Measurements: Each pulley has a 4.2" outer diameter, 5/8" bore, and uses a standard ball bearing. Compare to your old pulley before ordering – if yours is smaller or larger, this won’t work.

Key Things to Know

• Quality: Aftermarket pulleys with sealed ball bearings – comparable to OEM, but not genuine Craftsman/Husqvarna. Many users report good longevity.
• Installation: Easy swap – remove belt, unbolt old pulley, bolt this one on. No special tools needed. Takes about 15 minutes per pulley.
• Common gotcha: If your deck belt is worn or misrouted, the new pulley won’t fix vibration. Replace belt at the same time if it’s glazed or cracked.
• Pack of 3: Usually only one or two are needed per deck. You’ll have spares – store them dry to prevent rust.

Should You Buy It

If you need a reliable, affordable replacement for worn idler pulleys on a compatible Craftsman or Husqvarna model, this 3-pack is a solid value. It’s best for DIY owners who want to avoid dealership pricing and have a spare on hand. Not for those needing genuine OEM parts or who have non-standard deck sizes.
