What It Is

This is a replacement deck spindle assembly for 42" cutting decks on Cub Cadet LTX1040, LTX1042, and ZTT42-i1042 models, as well as Craftsman Revolution mowers. It drives the mower blade and is essential for smooth cutting.

Fitment & Compatibility

• Deck size: Only fits 42" decks—measure your deck width before ordering.
• Models: Confirmed for Cub Cadet LTX1040, LTX1042, ZTT42-i1042, and Craftsman Revolution with 42" deck.
• OEM cross-references: Replaces OEM part numbers 918-04512B, 918-04512, 618-04512B, 618-04512A, and 618-04512.
• Physical check: Measure spindle shaft diameter (typically 5/8") and bolt hole spacing (usually 3" center-to-center) to confirm match. Compare old spindle height—this unit is standard for these decks.
• Note: Aftermarket part, not OEM. Verify your mower’s model number under the seat or on the frame.

Key Things to Know

• Quality: Aftermarket spindle with sealed bearings; good value but may not last as long as OEM in heavy use.
• Installation difficulty: Moderate. Requires removing deck, belt, blade, and pulley. Have a puller if spindle is seized.
• Common gotcha: Spindle housing can crack if overtightened—torque mounting bolts to spec (usually 25-35 ft-lbs).
• Belt routing: Mark belt path before removal; misrouting causes vibration or poor cut.

Should You Buy It

If you need a budget-friendly replacement for a worn spindle on a 42" Cub Cadet or Craftsman Revolution, this is a solid choice. Best for occasional mowing or DIY repairs where OEM cost isn’t justified. Avoid if you demand maximum durability for commercial use.
