ILONPA 2 Pack 618-06976 918-06976 Spindle Assembly - Fits 42 inch Deck for Cub Cadet XT1-LT42 XT2-LX42 for MTD 131PA1ZS099 CYT4220, for Craftsman T7800 Replaces Spindle 618-06976A 918-06976A

What It Is

This is a replacement spindle assembly for 42-inch cutting decks on select Cub Cadet, MTD, and Craftsman lawn tractors. The spindle houses the blade shaft and bearings, transferring power from the belt to spin the mower blades.

Fitment & Compatibility

Before buying, verify your mower’s model number (not just the brand). This spindle fits:

• Cub Cadet XT1-LT42, XT2-LX42 (42-inch deck)
• MTD 131PA1ZS099, CYT4220
• Craftsman T7800 (and other models with 42-inch deck using OEM spindles 618-06976, 918-06976, 618-06976A, or 918-06976A)

Measure your existing spindle: housing diameter is ~2.5 inches, shaft length is ~2.75 inches, and bolt pattern is 3 holes on a 3-inch center. If your deck is wider or narrower than 42 inches, this will not fit. Check the stamped deck ID (e.g., “42A” or “42M”) under the footplate.

Key Things to Know

• Quality: Solid aftermarket replacement with sealed bearings. Many users report it’s comparable to OEM at half the price. Some note the paint finish may chip faster than OEM.
• Installation: Moderate difficulty – requires removing the deck, belt, and blade, then unbolting the old spindle. Have a socket wrench, torque wrench (blade bolt ~50 ft-lbs), and penetrating oil for rusted bolts.
• Common gotcha: The included bolts may be slightly different thread pitch than your deck. Test-fit before tightening; reuse OEM bolts if needed.
• Pack size: Comes as a 2-pack – you only need one per spindle location, but having a spare is handy if you have a second spindle that’s worn.

Should You Buy It

If you need to replace a failed spindle on a 42-inch Cub Cadet XT1/XT2, MTD, or Craftsman T7800 and want a cost-effective option that works reliably, this is a solid choice. It’s not for non-42-inch decks or for those expecting exact OEM fit/finish, but for most DIY repairs it’s a good value.
