MaxPower 332516B Spindle Pulley Replaces AYP/Craftsman/Husqvarna/Poulan 195945 197473 532195945

What It Is

The MaxPower 332516B is a replacement spindle pulley that drives the mower blade on riding lawn tractors and zero-turn mowers. It’s designed for AYP, Craftsman, Husqvarna, and Poulan models, replacing OEM part numbers 195945, 197473, and 532195945.

Fitment & Compatibility

Before buying, verify your mower’s deck size and model number. This pulley fits 38-inch to 54-inch decks on most Craftsman, Husqvarna, and Poulan tractors built after 2000, but it’s not universal. Measure the original pulley’s outside diameter (should be 4.0 inches) and check the center hole size (common sizes: 5/8-inch or 3/4-inch). Also confirm the pulley has a flat or crowned profile—this one is flat, so it won’t work with V-belt systems requiring a groove. Cross-reference your mower’s model number with MaxPower’s fitment list online.

Key Things to Know

• Quality: Made from stamped steel with a zinc finish—good for the price, but not as durable as OEM cast iron. Expect 2-3 seasons of normal use before bearing wear.
• Installation difficulty: Moderate. You’ll need a socket set, a puller to remove the old pulley from the spindle shaft, and possibly a hammer. Watch for stubborn rust on older decks.
• Common gotcha: The pulley’s center hole is unthreaded—you must reuse the original bolt or buy a new one separately. Also, check the spindle shaft keyway; if it’s worn, the pulley may slip.
• Belt compatibility: Works with A-section or B-section V-belts, but verify belt width (usually 1/2-inch or 5/8-inch) to avoid premature wear.

Should You Buy It

If you need a budget-friendly replacement for a worn spindle pulley on a Craftsman or Husqvarna tractor and you’re comfortable with basic mechanical work, this is a solid choice. It’s best for DIY repairs on older or secondary mowers, not for heavy commercial use where OEM durability is critical.
