618-0660 918-0625B 918-0660A Lawn Mower Spindle Assembly Fit for MTD White LT2200, for Cub Cadet LT1045 LT1046 i1046 for 46" Deck Tractor (3pack)

What It Is

This is a three-pack of spindle assemblies (models 618-0660, 918-0625B, 918-0660A) designed for 46-inch deck lawn tractors, including MTD White LT2200 and Cub Cadet LT1045, LT1046, and i1046 models. Each spindle houses the bearings and pulley that drive a mower blade; replacing worn or broken spindles restores cutting performance and reduces vibration.

Fitment & Compatibility

• Deck size: Fits 46-inch cutting decks only. Measure your deck width to confirm.
• Tractor models: Directly compatible with Cub Cadet LT1045, LT1046, i1046, and MTD White LT2200. Also fits many MTD, Yard Machines, Troy-Bilt, and other brands using the same 46" deck platform—check your deck’s OEM part numbers.
• OEM vs aftermarket: This is an aftermarket replacement. It matches OEM part numbers 618-0660, 918-0625B, and 918-0660A. Verify your old spindle’s part number (stamped on the housing) or cross-reference using your tractor’s model/serial.
• Measurements: Spindle shaft diameter should be 5/8" (common for 46" decks). Confirm pulley bolt pattern (typically 2.5" center-to-center) and overall height (about 4.5") before buying.

Key Things to Know

• Quality varies: With a 3.4/5 rating from only 3 reviews, expect basic construction. Some users report shorter bearing life than OEM Cub Cadet spindles. Inspect bearings for smooth rotation upon arrival.
• Installation difficulty: Moderate—requires removing the deck, unbolting the old spindle, and transferring the pulley and blade. You’ll need a socket set, torque wrench (blade bolt torque: ~70-90 ft-lbs), and possibly a puller for seized spindles.
• Common gotcha: The 3-pack includes three identical spindles, but some decks use left-hand threads on one spindle (check your deck). If so, this set may not work for that position. Always verify thread direction before installing.
• Warranty: Aftermarket parts typically have a limited warranty (30-90 days). This set likely has no manufacturer support beyond the seller’s return policy.

Should You Buy It

Buy this if you need a budget-friendly 3-pack to replace all three spindles at once on a 46" Cub Cadet or MTD tractor, and you’re comfortable with basic mechanical work. Skip it if you want OEM durability, need single-spindle replacements, or have a deck with a left-hand thread spindle—buy genuine Cub Cadet spindles instead for reliability.
