196104 Idler Pulley Fits for Hus qvarna Craftsman Mower, 197380 Flat Idler Pulley Bearing for HU AYP Craftsman TS342, TS343, TS348 Lawn Tractor 48" 54" Deck, Replace 532196104, 1 Pack

What It Is

This is a flat idler pulley (part #196104 / 532196104) that guides and tensions the drive belt on 48" and 54" mower decks. It’s used on Husqvarna, Craftsman, and AYP (American Yard Products) lawn tractors to keep belt alignment smooth during cutting.

Fitment & Compatibility

• Check deck size first: This pulley fits 48" and 54" decks only (models TS342, TS343, TS348). It will not work on 42" or smaller decks.
• OEM cross-reference: Replaces factory part numbers 196104, 532196104, and 197380. Verify your mower’s part number matches one of these.
• Brand fit: Works on Husqvarna, Craftsman, and AYP (now Husqvarna Group) tractors. Not universal—avoid using on John Deere, MTD, or Toro without checking measurements.
• Measure before buying: Outer diameter should be ~3.5" (89mm) with a 5/8" (16mm) bore. If your original pulley is larger or smaller, this won’t fit.

Key Things to Know

• Bearing quality: This is a sealed ball bearing pulley—smoother and longer-lasting than plastic or bushing types. No maintenance needed.
• Installation difficulty: Easy (15–30 minutes). You’ll need a socket wrench and possibly a belt removal tool. No special skills required.
• Common gotcha: The flat pulley design means the belt rides on the flat face, not a groove. If your deck uses a grooved pulley, this won’t work.
• Wear check: If your belt is squealing or deck is uneven cutting, inspect this pulley for wobble or rough spin. Replace in pairs if the other idler also shows wear.

Should You Buy It

If you own a Husqvarna, Craftsman, or AYP tractor with a 48" or 54" deck and need a direct OEM-replacement idler pulley, this is a reliable, budget-friendly choice. It’s well-rated for durability and fit, and the price is fair. Avoid it if your deck size is different or your original pulley has a groove.
