918-06977 618-06977 Spindle Assembly, 46" Deck Fit for Cub Cadet XT1-LT46 XT2-LX46 KH XT2-LX KW XT2-LX46, LE FAB Craftsman T8200 T8600 T3100 T2800 T240 T225 Mower 2 Pack

What It Is

This is a 2-pack of spindle assemblies designed for 46-inch fabricated (FAB) decks on select Cub Cadet, Craftsman, and MTD lawn tractors. It’s the replacement part for the rotating hub that holds the blade and houses the bearings, so your mower deck actually cuts instead of wobbling or making noise.

Fitment & Compatibility

• Deck size: Fits 46" fabricated decks only—not stamped steel decks. Measure your deck’s blade-to-blade span to confirm.
• Models: Compatible with Cub Cadet XT1-LT46, XT2-LX46 (both KH and KW engine variants), and Craftsman T8200, T8600, T3100, T2800, T240, T225. Also fits select MTD and Troy-Bilt tractors with the same FAB 46" deck.
• OEM vs aftermarket: This is an aftermarket replacement for OEM part 918-06977 / 618-06977. Cross-check your original part number under the deck or in your manual.
• Measurements: Spindle shaft is 0.625" (5/8") diameter, housing bolt pattern is 3" center-to-center. Verify your old spindle matches before buying.

Key Things to Know

• Quality: Most reviews note good build quality for the price—metal housing and sealed bearings. A few report bearing noise after heavy use, so expect 1-2 seasons of home-use life.
• Installation: Moderate difficulty—requires removing the deck, a socket set, and a torque wrench (blade bolt torque is typically 40-50 ft-lbs). Use threadlocker on bolts.
• Common gotcha: The pulley may not match your original if you have a different belt routing. Swap your old pulley onto this spindle if needed—same shaft size.
• Pack includes: 2 complete spindles with bearings and shafts, but no blades or pulleys. You’ll reuse your existing pulleys.

Should You Buy It

This is a solid value for DIY homeowners replacing a worn or noisy spindle on a 46" fabricated deck. It’s not heavy-duty enough for commercial use, but for $46 (for two), it’s cheaper than a single OEM spindle and works fine for seasonal cutting. If you need exact OEM fit or run a zero-turn mower, skip it.
