8TEN Mower Spindle for MTD Cub Cadet 46 inch XT1-LT46 XT2-LX46 KH KW FAB 918-06977 918-06977A 2 Pack

What It Is

This is a 2-pack of aftermarket mower spindles designed to replace the OEM spindles on MTD and Cub Cadet 46-inch fabricated steel decks. They’re the rotating assembly that holds the blade and connects it to the belt drive—essential for smooth, vibration-free cutting.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size and type: Fits only 46-inch fabricated steel decks (not stamped steel). Common on Cub Cadet XT1-LT46, XT2-LX46, and select KH/KW/FAB models.
• OEM part numbers: Direct replacement for 918-06977 and 918-06977A. Cross-check your old spindle’s number.
• Measurements: Spindle housing height is 4.25 inches, bolt pattern is 3.25 inches center-to-center, and shaft diameter is 5/8 inch. Measure your deck’s mounting holes and blade shaft to confirm.

Key Things to Know

• Build quality: These are aftermarket, not OEM. Most users report they’re durable, but a few note slightly looser tolerances than factory parts. Check shaft runout before final install.
• Installation difficulty: Moderate. You’ll need a jack, socket set, and torque wrench. Expect 30–60 minutes per spindle. Remove the blade, pulley, and old spindle—then bolt the new one in. No special tools required.
• Common gotcha: The included grease fitting is small—use a needle-style grease gun adapter. Also, the spindle bolts may need thread locker; they can loosen over time if not torqued to spec (about 35–40 ft-lbs).
• Pack size: Sold as a 2-pack, which is smart since spindles often fail in pairs. If only one is bad, you’ll have a spare.

Should You Buy It

If you have a 46-inch fabricated deck Cub Cadet or MTD and need a reliable, cost-effective replacement for worn or wobbly spindles, this 2-pack is a solid choice. It’s not premium OEM, but for the price, it gets the job done for most homeowners and light commercial use. Skip it if you demand factory-perfect tolerances or need a single spindle.
