179114 Flat Idler Pulley Replacement for Craftsman LT1000 Idler Pulley- Compatible with Hu sqvarna Po Ulan Pro AYP Riding Mower, Replace 532179114 12644 280-934, 1 Pack

What It Is

This flat idler pulley (OEM part 179114) routes and tensions the drive belt on select riding mower decks, ensuring the blade spins at the correct speed. It’s a direct replacement for the OEM pulley found on many Craftsman LT1000, Husqvarna, Poulan Pro, and AYP models.

Fitment & Compatibility

Check these before buying:

• Deck size: Fits most 42”, 46”, and 50” decks on compatible tractors—verify your deck’s belt routing diagram.
• Brands/models: Works on Craftsman LT1000/2000, Husqvarna YTH/YTA series, Poulan Pro PP/PR series, and other AYP-built riders. Not universal—cross-reference your model number.
• OEM vs aftermarket: This is a non-OEM replacement for OEM part #532179114, 12644, and 280-934. It meets OEM specs but isn’t branded Craftsman.
• Measurements: Pulley diameter is 3.5”, shaft hole is 3/8”, and it has a shielded bearing. Measure your old pulley to confirm these match.

Key Things to Know

• Quality note: The shielded bearing is sealed and pre-lubricated—should last as long as OEM. A few users report slightly more noise than original, but no functional issues.
• Installation difficulty: Easy—typically requires a socket wrench and maybe a belt removal tool. No special skills needed.
• Common gotcha: The flat face must align perfectly with the belt’s flat side. If your deck uses a V-belt, this pulley won’t work.
• Check belt condition: If the pulley failed, the belt may be worn or misaligned. Replace both for best results.

Should You Buy It

If you need a budget-friendly, drop-in replacement for a worn or noisy idler pulley on a Craftsman LT1000 or similar AYP-based riding mower, this is a solid choice. It fits common decks, installs in minutes, and saves you $10–15 vs. OEM. Not for commercial use or odd-sized pulleys—measure first.
