2 Pack 918-06989 Spindle Assembly with 954-04219 Deck Belt 1/2x103 | Replace 618-06989 for Craftsman T140 T150 T1500 T1600 T1700 T2600, Huskee LT4600, Troy Bilt Bronco 46, TB46, Horse XP 46 Deck

What It Is

This is a 2-pack of spindle assemblies (918-06989) plus a 1/2x103-inch deck belt (954-04219) for 46-inch cutting decks on specific Craftsman, Huskee, and Troy-Bilt lawn tractors. The spindles drive the blades, and the belt connects the engine pulley to the spindles—essential for mowing performance.

Fitment & Compatibility

• Deck size: Only for 46-inch decks—measure your deck width before buying.
• Models: Craftsman T140, T150, T1500, T1600, T1700, T2600; Huskee LT4600; Troy-Bilt Bronco 46, TB46, Horse XP 46. Also replaces OEM part 618-06989.
• Belt specs: 1/2-inch wide, 103-inch outside length. Verify your old belt’s length (measure end-to-end) to confirm fit.
• OEM vs aftermarket: These are aftermarket spindles and belt. Check pulley diameter (commonly 4.5 inches) and spindle shaft size (typically 7/8-inch hex) to match your deck. If your deck uses a different pulley or shaft, these won’t work.

Key Things to Know

• Quality: Aftermarket spindles may have thinner bearings than OEM—expect 2-3 seasons under normal use. The belt is standard, but ensure it’s routed correctly (check your deck diagram).
• Installation: Moderate difficulty—requires removing blades, pulleys, and deck. Use a puller for stuck pulleys. Torque spindle bolts to 30-40 ft-lbs; overtightening can warp housings.
• Common gotchas: The belt may be slightly tight on some decks—adjust tensioner if needed. Spindle bolts often rust; soak with penetrating oil before removal. Always replace blades when swapping spindles to avoid imbalance.
• Pack contents: Two spindles (not three—some 46-inch decks use three, but your listed models use two). The belt is a single unit; buy a second if spares needed.

Should You Buy It

Buy this if you own a listed 46-inch Craftsman, Huskee, or Troy-Bilt tractor and need a budget-friendly spindle kit with a matching belt. It’s a solid value for DIYers comfortable with moderate mechanical work, but skip if you prefer OEM durability or have a three-spindle deck.
