8TEN Blade Spindle Kit for Cub Cadet CC30 CC30H Craftsman R1000 R105 R110 Troy Bilt TB30 TB30R 942-04385 918-04822B

What It Is

This is a blade spindle assembly that houses the bearings and shaft your mower blade mounts to. It’s designed for single-blade, 30-inch deck walk-behind mowers from Cub Cadet, Craftsman, and Troy-Bilt, typically used on residential lawns.

Fitment & Compatibility

• Deck size: Fits 30-inch cutting decks only. Do not use on 28-inch or 32-inch decks.
• Models: Cub Cadet CC30, CC30H; Craftsman R1000, R105, R110; Troy-Bilt TB30, TB30R. Also fits some MTD-built variants.
• OEM cross-references: Replaces Cub Cadet 942-04385 and 918-04822B (check your original part number stamped on the old spindle).
• Measurements: Overall shaft length ~4.5 inches, mounting bolt pattern 3 inches center-to-center. Blade bolt is 5/16-24 thread. Measure your old spindle before buying.
• What to verify: Ensure your deck uses a single-spindle (not twin-blade) design. If your mower has a different OEM number, it may not match.

Key Things to Know

• Build quality: 8TEN spindles are aftermarket but use sealed bearings and a steel housing. They’re comparable to OEM, not heavy-duty commercial grade.
• Installation difficulty: Moderate – requires removing the blade, belt, and 4 bolts. A socket set and torque wrench (35-45 ft-lbs for spindle bolts) are needed. Expect 30-45 minutes.
• Common gotcha: The included grease fitting is easy to miss. Apply grease before installation to extend bearing life.
• Noise: If you hear grinding after install, check that the blade is not hitting the deck or that the spindle isn’t cross-threaded.

Should You Buy It

Buy this if you need a reliable, drop-in replacement for a worn-out spindle on a 30-inch Cub Cadet, Craftsman, or Troy-Bilt mower and want to save some money over OEM. It’s a solid value for DIY homeowners, but if you mow commercially or want a premium bearing, consider a higher-end brand.
