8TEN Deck Rebuild Kit for Cub Cadet Troy Bilt MTD 42 inch LT1040 LT1042 Bronco Super Blade Spindle Belt Idler

What It Is

The 8TEN Deck Rebuild Kit is an all-in-one replacement package for the cutting deck on 42-inch Cub Cadet, Troy-Bilt, and MTD lawn tractors. It includes spindles, blades, belts, and idler pulleys needed to restore deck performance on models like the LT1040, LT1042, and Bronco.

Fitment & Compatibility

Before buying, confirm your deck width is exactly 42 inches and that your tractor is a Cub Cadet, Troy-Bilt, or MTD with a stamped steel deck (not fabricated). This kit fits the LT1040, LT1042, and Bronco series, but also works on many MTD-built tractors from the early 2000s onward. Check the spindle bolt pattern and belt length against your OEM parts: the spindles use a 5/8-inch shaft and the belt is typically 92.5 inches. Measure your existing belt and spindle housing width to avoid mismatches. This aftermarket kit replaces OEM part numbers like 918-04194 (spindle), 942-04300 (belt), and 742-04192 (blade). It does not fit 46-inch or 50-inch decks.

Key Things to Know

• Quality vs OEM: The spindles and blades are solid for the price, but the belt and idler pulleys may wear faster than genuine Cub Cadet parts. Expect 1-2 seasons of moderate use before replacing the belt.
• Installation difficulty: Moderate. You’ll need a socket set, a torque wrench (spindle nuts to 30-40 ft-lbs), and a jack to access the deck. Plan 1-2 hours. The blades come unsharpened—sharpen them before first use.
• Common gotcha: The kit includes a flat idler pulley, but some decks use a grooved pulley. Verify your original idler style; if it’s grooved, you’ll need to buy a separate pulley.
• Missing hardware: The kit does not include spindle bolts or lock washers. Reuse your old ones or purchase new grade-8 bolts separately.

Should You Buy It

Buy this kit if you need a cost-effective, one-stop rebuild for a 42-inch MTD deck on a budget and are comfortable with a few hours of DIY work. Skip it if you want OEM-grade longevity or if your deck uses a grooved idler pulley—you’ll save time and hassle with genuine parts.
