What It Is

This is a deck spindle rebuild kit for 46-inch cutting decks, designed to replace worn bearings, seals, and hardware in the spindle assembly. It fits Cub Cadet XT1-LT46, XT2-LX46, and select Craftsman/MTD models with the 618-06977 or 918-06977 spindle.

Fitment & Compatibility

• Deck size: 46-inch only. Measure your deck width—if it’s not exactly 46 inches, this kit won’t fit.
• Spindle part numbers: Confirm your spindle is model 618-06977 or 918-06977. Check the stamped number on the spindle housing or your owner’s manual.
• Blade compatibility: Accepts blades 742-04244, 742-04290, or 942-04244. If your blades have a different part number, verify center hole diameter (typically 1-inch) and overall length before buying.
• Brands: Direct fit for Cub Cadet XT1-LT46, XT2-LX46, and many Craftsman/MTD models (T240, T225, T8200, T8600, T3100, T2800). Not guaranteed for other brands—cross-reference your deck’s spindle assembly.
• OEM vs aftermarket: This is an aftermarket kit. OEM Cub Cadet spindle rebuild kits cost more but may offer tighter tolerances.

Key Things to Know

• Quality concerns: At 4.0 stars with only 5 reviews, reliability is unproven. Some users report bearings wearing faster than OEM.
• Installation difficulty: Moderate. Requires removing the deck, disassembling the spindle, pressing out old bearings, and pressing in new ones. A bench vise and bearing press tool help.
• Common gotcha: The kit includes two blades—verify your deck uses 2 blades, not 3. Some 46-inch decks (e.g., older models) may have a different blade count.
• Check for spindle housing damage: If the housing is bent or cracked, a rebuild kit won’t fix it. Inspect before ordering.

Should You Buy It

Buy this if you have a 46-inch Cub Cadet, Craftsman, or MTD mower with a 618-06977/918-06977 spindle and want a budget rebuild option. Skip it if you prefer OEM reliability, need a 3-blade deck kit, or suspect the spindle housing is damaged—buy a complete spindle assembly instead.
