Spindle Assembly Replacement AYP 130794 532130794 Craftsman LT1000 Riding Mower 36, 38"& 42" AYP with Ventilated Decks

What It Is

The spindle assembly (part number 130794 / 532130794) is the rotating hub that drives your mower blades. It’s a direct replacement for Craftsman LT1000 series riding mowers with 36", 38", or 42" AYP ventilated decks, and for other AYP/Craftsman models using the same deck design.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size & type: Fits only ventilated (open-sided) decks in 36", 38", and 42" widths. Not for stamped or fabricated decks without ventilation slots.
• Model series: Works with Craftsman LT1000, LT1500, LT2000, GT3000, and some Husqvarna/YP mowers using AYP spindles. Check your model number (found under seat or on deck).
• Measurements: OEM spindle has a 1" diameter shaft with a 5/8" keyway, 3-bolt pattern, and overall height of about 4.5". Measure your old spindle to verify – aftermarket versions may vary slightly in housing thickness.

Quick check: Look for part number 130794 or 532130794 on your old spindle. If it matches, this is a drop-in fit.

Key Things to Know

• Quality: This is an aftermarket replacement, not OEM. Expect comparable durability for homeowner use, but may not match OEM for commercial-duty longevity.
• Installation difficulty: Moderate. You’ll need a socket set, a puller for the pulley, and possibly a hammer to free seized bolts. Plan 30–60 minutes per spindle.
• Common gotcha: The pulley bolt is often reverse-threaded on AYP decks – turn clockwise to loosen. Use penetrating oil on rusted bolts.
• Bearing life: Pre-greased, sealed bearings. No maintenance needed, but running with a dull blade or hitting obstacles will shorten lifespan.

Should You Buy It

If you own a Craftsman LT1000 or similar AYP mower with a ventilated deck and need to fix a wobbly or seized blade, this spindle is a solid, affordable fix. It’s not for heavy commercial use, but for residential mowing, it’s a proven replacement with strong reviews.
