918-04822A 42" Deck Spindle Assembly for Cub Cadet MTD 918-04822A 918-04822B 618-04822 918-04889 30-8001 14328 82-058 Fit 42inch and 30-in Mini Riders with Bolt Zerk Grease Pulley OD 6" 2Pcs

What It Is

This is a complete spindle assembly for the 42-inch cutting deck on Cub Cadet and MTD lawn tractors, including select 30-inch mini riders. It replaces the factory spindle and pulley when the original bearings fail or the housing gets damaged, restoring blade rotation for a clean cut.

Fitment & Compatibility

• Deck size: Fits 42-inch decks (most common) and 30-inch mini rider decks. Measure your deck width before ordering.
• Model/brand: Direct replacement for Cub Cadet and MTD models using OEM part numbers 918-04822A, 918-04822B, 618-04822, 918-04889, 30-8001, 14328, and 82-058.
• OEM vs aftermarket: This is an aftermarket assembly, not genuine Cub Cadet. It matches OEM specs but verify pulley OD is exactly 6 inches (as listed) to match your belt routing.
• Physical check: Ensure your deck uses a bolt-style spindle (not a snap-ring or press-fit). The assembly includes a zerk grease fitting for maintenance.

Key Things to Know

• Quality: Rated 4.6/5 from 921 reviews—users report it’s as durable as OEM for a lower price. Some note the paint may chip, but function is solid.
• Installation difficulty: Moderate. Requires removing the deck, unbolting the old spindle, and transferring the blade. A socket set and torque wrench are needed. Expect 30–60 minutes per spindle.
• Common gotcha: This is a two-piece set, so you get two complete spindles. If your deck only has one bad spindle, you’ll have a spare—no need to buy separately.
• Grease fitting: The zerk fitting lets you lubricate bearings regularly, extending life. Don’t skip this step after installation.

Should You Buy It

If you need a reliable, cost-effective replacement for a worn 42-inch or 30-inch deck spindle on a Cub Cadet or MTD mower, this is a solid choice. It’s well-reviewed and includes two spindles, making it a good value for decks with multiple spindles or for keeping a spare on hand. Avoid if you require OEM-only parts for warranty or exact paint match.
