8TEN Blade Spindle Belt Kit for Cub Cadet 46 inch Deck LT 1045 1046 918-0660A 918-0660B 942-0644 954-04153A

What It Is

This is a replacement spindle and belt kit for 46-inch deck Cub Cadet lawn tractors (LT 1045, 1046, and similar models). It drives the mower blades via the deck’s pulley system, replacing worn or failed spindles and the drive belt in one set.

Fitment & Compatibility

• Deck size: 46-inch stamped or fabricated deck only. Not for 42-inch or 54-inch decks.
• Models confirmed: LT 1045, LT 1046, LT 1042, LT 1050, LTX 1045, LTX 1046, and many XT1/XT2/XT3 variants with a 46-inch deck.
• OEM part numbers: Replaces 918-0660A, 918-0660B, 942-0644, 954-04153A. Check your old part number for exact match.
• Measurements before buying: Measure spindle pulley diameter (should be ~4.5 inches) and belt length (~96.5 inches). If your pulleys or belt are different, this kit won’t fit.
• Brand note: This is an aftermarket kit, not genuine Cub Cadet. Fitment is generally good, but some users report needing to swap the belt for an OEM belt if the aftermarket belt is slightly off.

Key Things to Know

• Quality: Spindles are solid but may have slightly looser bearings than OEM. Fine for homeowner use, but commercial operators should stick with genuine Cub Cadet for longevity.
• Installation difficulty: Moderate. Requires removing the deck, unbolting old spindles (3 bolts each), and routing the belt. A pulley puller or impact wrench helps with stubborn spindle nuts.
• Common gotcha: The aftermarket belt included may be slightly too long or short. If the belt slips or doesn’t tension correctly, buy an OEM belt separately (part 954-04153A).
• What’s in the box: 2 spindles (some kits include 3), 1 drive belt, and mounting hardware (bolts, washers, lock nuts). Verify you have all parts before starting.

Should You Buy It

If you own a Cub Cadet with a 46-inch deck, need to replace both spindles and the belt, and want a budget-friendly one-stop kit for homeowner use, this is a solid choice. Skip it if you need commercial-grade longevity or if your deck uses a different belt length—buy OEM parts separately instead.
