918-04865A Spindle Assembly fit for Cub Cad Mower - 618-04636 Deck Spindles fit for Cub Cad LTX1045 LTX1046, Craftsman LT2000 LT2500, Greasable Spindle for Troy Bilt MTD Riding Lawn Tractor

What It Is

This is a greasable spindle assembly that drives and supports the mower deck blades. It’s designed for residential riding mowers from Cub Cadet, Craftsman, Troy-Bilt, and MTD with 42–54-inch fabricated or stamped decks.

Fitment & Compatibility

Before buying, verify your mower’s model number and deck size. This spindle replaces OEM part 918-04865A and fits many Cub Cadet (LTX1045, LTX1046), Craftsman (LT2000, LT2500), and Troy-Bilt/MTD models with 42- or 46-inch decks. Measure the spindle shaft diameter (should be 5/8-inch) and overall length (about 4.75 inches). Check your deck’s mounting pattern—this uses three 5/16-inch bolts spaced 2.5 inches apart. Not compatible with zero-turn or commercial mowers.

Key Things to Know

• Greasable design – Has a Zerk fitting for periodic lubrication, which extends bearing life compared to sealed units.
• Installation difficulty – Moderate. Requires removing the deck, blade, pulley, and old spindle. Basic hand tools and a torque wrench are needed.
• Common gotcha – The pulley bolt is reverse-threaded on some models. Verify rotation direction before forcing.
• Build quality – Aftermarket part with solid reviews; not OEM, but uses double-sealed bearings and cast iron housing for durability.

Should You Buy It

Yes, if you need a budget-friendly, greasable replacement for a worn spindle on a residential Cub Cadet, Craftsman, or Troy-Bilt riding mower. It’s a reliable aftermarket option with strong user ratings, but verify your deck’s bolt pattern and shaft specs first.
