What It Is

This 42-inch mower deck rebuild kit replaces the spindle, pulley, belt, blade, and idler on select AYP/Craftsman/Poulan/Husqvarna lawn tractors (e.g., LT1000, LT2000, YTH1842). It’s designed for a full deck refresh when components are worn, bent, or seized.

Fitment & Compatibility

• Deck size: 42-inch stamped deck only (not 46" or 54").
• Brands/models: AYP-built Craftsman, Poulan, Husqvarna, and some older MTD models with a 42" deck. Check your model number against OEM part 130794 (spindle) and 144959 (belt).
• OEM vs aftermarket: This is an aftermarket kit; OEM part numbers are 532130794 (spindle), 129861 (pulley), 144959 (belt), 134149 (blade), and 131494 (idler). Verify your existing parts match these numbers.
• Measurements: Belt is 1/2" wide x 95 1/2" long. Blade is 16.5" long. Spindle shaft is 5/8" diameter (fits standard pulleys). Measure your old belt and blade length before buying.

Key Things to Know

• Quality: Aftermarket parts may have slightly looser tolerances than OEM. Check spindle bearing play and pulley alignment after install.
• Installation difficulty: Moderate—requires removing the deck, swapping the spindle, pulley, idler, and belt, then re-tensioning. A socket set, wrench, and jack/stands are needed.
• Common gotchas: The idler pulley bracket may need the old bearing pressed out and new one in; not all kits include the bracket. Also, the blade bolt torque is ~40-50 ft-lbs—don’t overtighten.
• Belt routing: Double-check the belt path against your deck diagram—most 42" AYP decks use a “M” or “Z” pattern. Incorrect routing causes slipping or poor cut.

Should You Buy It

If your 42" AYP/Craftsman/Poulan/Husqvarna deck has a noisy spindle, slipping belt, or dull blade, this kit is a cost-effective one-stop fix. It’s best for DIYers comfortable with basic deck disassembly; if you need OEM exactness or have a different deck size, skip it.
