8TEN Deck Rebuild Kit for Cub Cadet MTD Troy Bilt XT1-LT50 Super Bronco 50 XP 50-Inch 954-04077 742P05094 618-09255

What It Is

This 8TEN deck rebuild kit replaces the complete spindle assembly, mandrels, pulleys, and bearings on 50-inch cutting decks used by Cub Cadet, MTD, and Troy-Bilt riding mowers like the XT1-LT50 and Super Bronco 50 XP.

Fitment & Compatibility

• Deck size: Only for 50-inch stamped steel decks (not fabricated or 46/54-inch models).
• OEM cross-reference: 954-04077, 742P05094, 618-09255 – if your mower uses any of these part numbers for the original spindle/housing, this kit fits.
• Check your deck’s spindle bolt pattern: Measure center-to-center on the three mounting holes – they should be 3.5 inches. If your deck uses a different pattern (e.g., 4-inch), this kit won’t work.
• Model series: Works on XT1-LT50, Super Bronco 50 XP, and most MTD/Troy-Bilt 50-inch decks from ~2010 onward. Verify your mower’s deck model number (stamped on the deck top) against the list in the product description.

Key Things to Know

• Quality: 8TEN is an aftermarket brand; bearings and pulleys are generally comparable to OEM, but some users report slightly tighter tolerances on spindle shafts. Grease them well before install.
• Installation difficulty: Moderate – you’ll need a socket set, torque wrench, and a puller for old bearings. Plan 2-3 hours if you’re mechanically handy; longer if the old spindles are rusted.
• Common gotcha: The kit includes new spindle housings, but the old deck mounting holes may be wallowed out. Check for ovaled holes – if present, add washers or replace the deck.
• Included vs. not: Kit comes with spindles, pulleys, bearings, and hardware. You may need to reuse your old blade adapters and blades – verify they’re in good shape.

Should You Buy It

If your 50-inch Cub Cadet or Troy-Bilt deck has wobbly spindles, noisy bearings, or uneven cut, this kit is a cost-effective rebuild vs. buying individual OEM parts. It’s a solid choice for DIY owners who want to refresh the entire deck at once and don’t mind aftermarket components. Skip it if your deck is severely rusted or you prefer factory parts for warranty reasons.
