42 Inch Deck 130794 Spindle Rebuild Kit for Craftsman LT1000 LT2000 DLT3000 DYT4000, with 2 Spindles Assembly 532130794, 2 Idlers 173437, 2 Blades 134149, 1 Belt 144959

What It Is

This is a complete rebuild kit for the 42-inch cutting deck on select Craftsman lawn tractors, containing two spindle assemblies, two idler pulleys, two blades, and one drive belt to replace worn-out deck components and restore cutting performance.

Fitment & Compatibility

Before buying, verify your mower has a 42-inch deck and fits one of these model families: Craftsman LT1000, LT2000, DLT3000, or DYT4000. The OEM part numbers for the spindles are 532130794 (or 130794), idlers 173437, blades 134149, and belt 144959. Measure your existing spindle bolt pattern (typically 3-inch center-to-center) and spindle shaft diameter (commonly 5/8-inch or 3/4-inch). Check that your deck uses two spindles (not three) and that the belt length matches your original (this belt is for 42-inch decks only). This is an aftermarket kit, not OEM Craftsman, so compare physical dimensions to your old parts if possible.

Key Things to Know

• Quality varies – Some users report aftermarket spindles may have thinner bearings or seals than OEM, potentially lasting 1-2 seasons instead of 3-4. Inspect for smooth rotation before installation.
• Installation difficulty is moderate – You’ll need basic tools (socket set, jack stands, possibly a puller for stubborn spindles). Expect 1–2 hours if you’ve done deck work before; longer if rusted.
• Common gotcha – The included blades may not be exactly the same shape or thickness as OEM. Check blade offset and length (should be ~21 inches for 42-inch decks). Replace all deck hardware (bolts, washers) if corroded.
• Belt tension matters – After installing, adjust the belt tension per your model’s manual. Too loose causes slipping; too tight wears pulleys and bearings.

Should You Buy It

This kit is a solid value if you need a full deck overhaul on a budget and are comfortable with moderate DIY work. It’s best for older Craftsman tractors where individual OEM parts would cost more than the whole mower is worth. Skip it if you want guaranteed long life or have a newer model still under warranty—OEM parts are safer there.
