What It Is

This rebuild kit replaces the wear-prone spindles, idler pulleys, and drive belt on 42-inch MTD/Cub Cadet lawn tractor decks, restoring blade rotation and belt tension. It’s designed for models like the LTX1040, LTX1042, and EZT-L42.

Fitment & Compatibility

• Deck Size: Only for 42-inch (107 cm) fabricated or stamped decks—measure your deck width before ordering.
• Brand/Model Fit: Fits MTD, Troy-Bilt, Cub Cadet, and Yard Machines tractors with a 42-inch deck. Common models: LTX1040, LTX1042, EZT-L42, RZT-L42. Check your tractor’s model number (stamped under seat or on frame) against the kit’s listed OEM numbers.
• OEM Cross-Reference: Spindles replace 918-04822A and 918-04822B; idlers replace 756-04129C; belt replaces 754-04060A. Verify these match your old parts.
• Measurements: Spindle housing is approx. 5.5” tall; belt is 96.5” long x 1/2” wide. Measure your existing belt length and spindle height to confirm.

Key Things to Know

• Quality: Aftermarket parts—decent for the price, but spindles may have slightly looser tolerances than OEM. Grease them before install for longer life.
• Installation Difficulty: Moderate. You’ll need a socket set, jack/stands to remove deck, and a puller for stuck spindles. Expect 1–2 hours.
• Common Gotchas: The idler pulleys may ship with different bearing seals than OEM—check for smooth spin before mounting. Belt length can vary by 0.5” on some decks; measure your old belt first.
• Included vs. Needed: Kit has 2 spindles, 2 idlers, 1 belt. You’ll need to reuse your deck mounting bolts and washers (not included). A new deck belt may also be required if yours is worn.

Should You Buy It

This kit is a solid value if you’re rebuilding a 42-inch MTD/Cub deck on a budget—covers the three most common failure points in one purchase. Skip it if you need OEM-grade spindles for heavy commercial use, or if your deck has bent pulley mounts. For weekend mowing on a 5–10 year old tractor, it’s a practical fix.
