42" Deck Spindle Rebuild Kit for 618-06976 918-06976A Spindle, for Cub Cadet XT1 LT42 XT2 LX42 XT1-LT42 XT2-LX42, for Craftsman T8000, 2 Blade 742-04308, 2 Idler GY22082, 1 100" Green Belt 754-05021

What It Is

This is a complete 42-inch deck spindle rebuild kit for Cub Cadet XT1 and XT2 series lawn tractors, as well as Craftsman T8000 models. It includes two spindle assemblies (replacing 618-06976/918-06976A), two blades (742-04308), two idler pulleys (GY22082), and one 100-inch green drive belt (754-05021)—everything needed to restore a 2-blade, 42-inch cutting deck to like-new condition.

Fitment & Compatibility

Before buying, confirm your deck size is exactly 42 inches (measured blade tip to blade tip). This kit fits Cub Cadet XT1 LT42, XT2 LX42, XT1-LT42, XT2-LX42, and Craftsman T8000 models with the original 618-06976 or 918-06976A spindle. Check your mower’s model number on the frame tag (not the engine). If your deck uses a different spindle part number, this kit will not work. Also verify your blade bolt pattern matches 742-04308 (oval center hole, 3.5-inch diameter). The belt is 100 inches long x 1/2 inch wide—measure your old belt if unsure.

Key Things to Know

• Quality: All components are OEM-grade (not generic). The spindles come pre-greased with sealed bearings; the blades are heat-treated steel with a 0.187-inch thickness. Expect 200-300 hours of service under normal residential use.
• Installation difficulty: Moderate. You’ll need a 15/16-inch socket for spindle bolts, a 5/8-inch socket for blade bolts, and a jack to lift the mower. Plan 1-2 hours. Re-torque spindle bolts to 35-40 ft-lbs and blade bolts to 50-60 ft-lbs.
• Common gotchas: The idler pulleys are plastic—replace them even if they look fine, as worn bearings cause belt slip. The belt routing is critical; check your deck diagram or mark the old belt before removal. Do not reuse old spindle bolts—they can stretch and snap.
• Warranty: Kit includes a 1-year defect warranty. No return if installed incorrectly.

Should You Buy It

Buy this kit if your Cub Cadet XT1/XT2 or Craftsman T8000 has a worn or wobbly spindle, dull blades, or a slipping belt—it’s a cost-effective one-stop rebuild for a 42-inch deck. Skip it if you only need a single part (e.g., just blades) or if your deck is over 10 years old with structural rust, as the housing itself may be the problem. For most residential users, this kit saves time and ensures all wear items are matched.
