What It Is

This is a replacement spindle pulley (OEM part #197473) that drives the mower deck belt on Husqvarna, Ariens, and AYP lawn tractors. It’s designed for 42" and 46" cutting decks, commonly used on models like the 2146XLS, 2246LS, 2346XLS, and CT series (CT153, CT154, CTH163T, CTH164T, CTH173).

Fitment & Compatibility

Before buying, check three things:

1. Part number match – This replaces OEM #195945, 197473, 532195945, 532197473, and AYP 197473. Compare with your original part number.
2. Deck size – Works on 42" and 46" decks only. Not for 48" or 50" decks.
3. Belt type – Typically used with a single-belt, deck-drive system. Confirm your mower uses a 3/8" or 1/2" belt width (measure old pulley groove).

Common compatible models: Husqvarna 2146XLS, 2246LS, 2346XLS; Ariens CT153, CT154, CTH163T, CTH164T, CTH173. If your model isn’t listed, verify by measuring the pulley’s outside diameter (should be ~4.5") and shaft hole size (usually 5/8").

Key Things to Know

• Quality – Aftermarket part, not OEM. Most buyers report it fits well and matches OEM specs. Some note the finish may be slightly rougher than original.
• Installation – Moderate difficulty. You’ll need a socket set, possibly a puller to remove the old pulley from its shaft. Expect 20–40 minutes per pulley.
• Common gotcha – The pulley’s center hole may be slightly tight on some spindles. Light sanding or a file can help. Also, check the spindle bearing condition—if the bearing is worn, the new pulley won’t solve vibration.
• Belt alignment – After installation, verify the belt tracks centered in the pulley groove. Misalignment can cause premature belt wear or throw the belt.

Should You Buy It

If you need a budget-friendly replacement for a worn or damaged spindle pulley on a 42" or 46" Husqvarna, Ariens, or AYP deck, this is a solid choice. It’s not premium OEM, but it’s reliable for most homeowners. Avoid if you require exact OEM fitment for commercial use or if your spindle bearing is also failing—replace both together.
