918-06977A 618-06977 Spindle Assembly - Fits 46 Inch Mower Deck Cub Cadet XT1-LT46 XT2-LX46 KH KW FAB Craftsman T8200 T8600 T3100 T2800 T240 T225(1-Pack)

What It Is

The 918-06977A / 618-06977 spindle assembly is the rotating hub that holds the mower blade and bearing housing on a 46-inch fabricated deck. It’s designed for Cub Cadet XT1-LT46, XT2-LX46, and specific Craftsman T-series lawn tractors (T8200, T8600, T3100, T2800, T240, T225) with 46-inch stamped or fabricated decks.

Fitment & Compatibility

• Deck size: Only for 46-inch decks. Measure your deck width from outside to outside of the shell.
• OEM vs aftermarket: This is an aftermarket replacement for OEM part numbers 918-06977A and 618-06977. It is not a genuine Cub Cadet or Craftsman part.
• Check your deck’s spindle mounting pattern: Measure center-to-center distance of the three mounting bolts (typically 3.5 inches). Also verify the spindle shaft diameter and length match your existing unit.
• Blade compatibility: Confirm the blade’s center hole size and shape (usually a 5-point star or 1-inch round) match the spindle’s drive pattern.
• Model cross-reference: Works on Cub Cadet XT1-LT46, XT2-LX46, and Craftsman T8200, T8600, T3100, T2800, T240, T225. If your tractor has a different model prefix, measure first.

Key Things to Know

• Quality vs OEM: Users report this spindle is functional but bearings may not last as long as the original Cub Cadet part. Expect 1-2 seasons of residential use.
• Installation difficulty: Moderate. You’ll need a socket set, a torque wrench (recommended 30-40 ft-lbs for mounting bolts), and possibly a puller to remove the old spindle. No special tools required.
• Common gotchas: The pulley may not be pre-installed—you’ll need to transfer your old pulley and belt. Also, the spindle housing can be slightly shorter than OEM; check blade clearance under the deck before running.
• Bearing replacement: This is a sealed assembly; you cannot replace just the bearings. If it fails, you buy a whole new spindle.

Should You Buy It

Buy this if you need a budget-friendly replacement for a worn-out spindle on a residential 46-inch deck and you’re comfortable with a moderate DIY install. Avoid if you want OEM longevity or if your deck sees heavy commercial use—invest in a genuine Cub Cadet spindle instead.
