618P09258 Replace 618-09258 Spindle Assembly Fits for Cub Cadet 46-Inch XT2-LX46 XT1-LT46 Troy Bilt 46 XP 46I XP MTD Craftsman T2400 Lawn Mower

What It Is

This is a replacement spindle assembly (OEM part 618-09258 / 618P09258) that houses the bearings and pulley for the mower blade. It’s designed for 46-inch cutting decks on Cub Cadet XT1 and XT2 series, Troy-Bilt XP, MTD, and Craftsman T2400 lawn tractors.

Fitment & Compatibility

Confirm these before ordering:

• Deck size: 46-inch stamped or fabricated deck only – not for 42-inch or 54-inch decks.
• Brands/models: Cub Cadet XT1-LT46, XT2-LX46; Troy-Bilt 46XP, 46I XP; MTD 46-inch; Craftsman T2400. Also fits some Yard Machines and Huskee 46-inch decks.
• OEM vs aftermarket: This is an aftermarket replacement (brand: Cub Cadet) that matches OEM specs. Original OEM part number is 618-09258.
• Measurements: Verify the spindle shaft diameter (typically 5/8-inch) and the mounting bolt pattern (3-bolt triangular, 3.5-inch center-to-center). Measure your old spindle before ordering – deck variations exist even within same inch size.

Key Things to Know

• Quality: Solid build with sealed bearings – holds up well for homeowner use. Not heavy-duty enough for commercial zero-turn mowers.
• Installation difficulty: Moderate. Requires removing the deck, detaching the blade, belt, and pulley. You’ll need a socket set, wrench, and possibly a puller for the pulley.
• Common gotchas: The blade bolt is reverse-threaded on most models (lefty-tighty). Also, the spindle may come without grease fittings – if your old one had them, you’ll need to add grease manually.
• Warranty: Typically 1-year limited – keep your receipt and original packaging.

Should You Buy It

If you own a 46-inch Cub Cadet XT1/XT2, Troy-Bilt XP, MTD, or Craftsman T2400 and need a direct-fit replacement without paying dealer markup, this is a reliable choice. It’s not for commercial use or decks other than 46-inch, but for residential mowing it’s a solid value at $40.89.
