2 Pack 532194326 V-groove Idler Pulley with 532194327 Flat Idler Pulley Replaces 194327 Idler Pulley Craftsman 194326 for Husqvarna YTH2348 LGT2654 YTH20K46 YTH21K46 YTH1542XP GT52XLS Tractor

What It Is

This is a 2-pack replacement idler pulley set for lawn tractor mower decks, designed to guide and tension the drive belt on select Craftsman and Husqvarna models. The set includes one V-groove pulley (532194326) and one flat pulley (532194327), essential for smooth blade engagement and belt longevity.

Fitment & Compatibility

Before purchasing, confirm your mower’s model number (e.g., YTH2348, LGT2654, YTH20K46, YTH21K46, YTH1542XP, GT52XLS) and deck size (typically 42–54 inches). These pulleys replace OEM part numbers 194326 and 194327. Measure your existing pulleys: the V-groove should have a 4.0-inch outer diameter and a 5/8-inch bore; the flat pulley should be 4.0 inches with a 1/2-inch bore. They are aftermarket replacements, not genuine OEM, so verify belt routing and pulley spacing on your deck to ensure a proper fit.

Key Things to Know

• Quality: Made from steel with sealed ball bearings, these are durable and comparable to OEM, but check for smooth spin out of the box—some units may have slight bearing drag.
• Installation difficulty: Easy to moderate; requires basic hand tools (wrench/socket set) and possibly a puller if the old pulley is seized. No special skills needed.
• Common gotchas: The flat pulley may have a different shoulder height than OEM, which can affect belt alignment on some decks. Always compare side-by-side before installing. Also, replace both pulleys simultaneously to avoid uneven wear.
• Belt compatibility: Ensure your drive belt is the correct width (typically 1/2-inch or 5/8-inch) for these pulleys—mismatched belts cause premature wear or slipping.

Should You Buy It

If you own a compatible Craftsman or Husqvarna tractor with a 42–54 inch deck and need a cost-effective, reliable replacement for worn or noisy idler pulleys, this 2-pack is a solid choice. It’s especially good for DIY owners who want to save on OEM markup and don’t mind a quick alignment check. Avoid if you require exact OEM specs for a non-listed model or need pulleys with a different bore size.
