What It Is

This is a 2-pack of spindle assemblies (part 918-06976) paired with an idler pulley (756-05034A) and a drive belt (954-05021), designed to replace the factory cutting deck components on select Cub Cadet XT1, XT2, and Craftsman T-series lawn tractors. It’s a complete service kit for restoring blade rotation and belt tension on 42-inch decks.

Fitment & Compatibility

• Deck size: Only fits 42-inch (LT42/LX42) decks. Measure your deck width before buying.
• Models: Cub Cadet XT1-LT42, XT2-LX42; Craftsman T210, T7800. Also fits some older LT42 models, but verify your OEM part numbers.
• OEM cross-reference: Replaces Cub Cadet 918-06976A, 918-06976, 618-06976A. The idler pulley (756-05034A) and belt (954-05021) are specific to these decks.
• Check your old parts: The spindle assembly includes bearings and housing—measure the bolt pattern (typically 3-bolt, 3.5-inch center). The belt is 1/2-inch wide x 95.5-inch length. If your deck uses a different belt length or pulley diameter, it won’t fit.

Key Things to Know

• Quality: These are OEM-style replacements, not genuine Cub Cadet. Expect decent performance for the price, but bearings may wear faster than factory parts under heavy use.
• Installation difficulty: Moderate. You’ll need a socket set, jack stands, and a wrench for the spindle bolts. Plan 1–2 hours for full replacement.
• Common gotchas: The idler pulley bracket may not align perfectly on older decks—check for wear on the bracket itself. The belt routing diagram is essential; take a photo before removing the old belt. Torque spindle bolts to 20–25 ft-lbs to avoid stripping.
• Pack contents: Two spindles, one idler pulley, one belt. No washers or lock nuts included—reuse or buy separately.

Should You Buy It

This kit is a good value if you need to replace a worn spindle or belt on a 42-inch Cub Cadet or Craftsman tractor and want a one-stop solution. It’s best for DIY homeowners with moderate mechanical skills, but if you’re a heavy user (mowing more than 2 acres weekly), consider genuine OEM spindles for longer life.
