2 Pack 918-06991 Spindle Assembly with 954-04060C Belt Replaces 618-06991, 918 06991, 91806991 for Craftsman 42" T110, T130, T1000, T1200, Huskee LT4200, Troy Bilt Pony 42, Bronco 42 Tractors

What It Is

This is a 2-pack of spindle assemblies (part 918-06991) plus a drive belt (954-04060C) for 42-inch cutting decks on select Craftsman, Huskee, and Troy-Bilt lawn tractors. The spindles drive the blades; the belt connects the engine to the deck. It’s a direct replacement for worn or damaged OEM parts.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch stamped steel deck (not fabricated). This set fits:

• Craftsman: T110, T130, T1000, T1200 (model numbers starting with 917, 247, or 944)
• Huskee: LT4200
• Troy-Bilt: Pony 42, Bronco 42

Check your model number under the seat or deck. The spindles replace OEM part numbers 618-06991, 918-06991, and 91806991. The belt replaces 954-04060C. Measure your old spindles: the shaft diameter should be 5/8-inch, and the overall length about 4.5 inches. The belt is 1/2-inch wide by 96.5 inches long. If your deck uses a different belt length or spindle design (e.g., 3/4-inch shaft), this won’t work.

Key Things to Know

• Quality: Aftermarket spindles are zinc-plated steel with sealed ball bearings. They’re comparable to OEM but may wear slightly faster under heavy use (dirt, tall grass).
• Installation: Moderate difficulty—requires removing the deck, unbolting 3 spindle bolts per spindle (likely 5/16-inch or 3/8-inch), and swapping the belt. Plan 1-2 hours. You’ll need a socket set, wrench, and possibly a puller if spindles are seized.
• Gotcha: The belt routing matters. Check your deck diagram or take a photo before removing the old belt. Misrouting causes poor cutting or belt slip.
• Gotcha: Spindle bolts are often torqued to 30-40 ft-lbs. Over-tightening can strip the housing. Use thread locker if bolts are loose.

Should You Buy It

Yes, if your 42-inch Craftsman, Huskee, or Troy-Bilt tractor has worn or wobbly spindles and a glazed or cracked belt. It’s a cost-effective kit for DIYers who want to replace both spindles and the belt in one go—saves ordering separately. Not for commercial use or decks larger than 42 inches.
