LTX1046 Spindle Assembly 918-04865A 2pcs - Direct Deck Replacement

In this review the focus is on the LTX1046 spindle assembly kit and who will benefit most from it. The kit includes two spindle assemblies with pulleys, tapped screws and plastic caps, and is aimed at owners of Cub Cadet, MTD, Troy-Bilt and related zero-turn and lawn tractor decks who need a direct deck replacement. The single biggest reason to consider this kit is its fit and convenience: buyers report the parts match the listed models closely and arrive ready to install, making it a practical option for routine deck rebuilds or replacing worn spindle units.

Key Features

• Direct fit for LTX1046 models: Designed to replace the factory spindle on LTX1045, LTX1046 and several related Cub Cadet decks, reducing guesswork during purchase.
• Pulley included: Each spindle is supplied with a pulley that has a 6-1/2' OD to match deck belt routing and avoid an extra part swap.
• Grease zerk installed: The spindle includes a grease fitting so routine lubrication is simple and can extend bearing life.
• Complete hardware pack: The package ships with tapped screws and plastic caps so installers have the common fasteners needed for a straightforward replacement.
• Broad model compatibility: Covers many Cub Cadet, MTD, Troy-Bilt and other mower model numbers so it can serve as a multi-application service part.

Who It's For

The kit is best suited for DIY lawn mower owners and small mower repair shops who work on Cub Cadet LTX1045/LTX1046 decks, LT2000 series tractors, or similar models from MTD and Troy-Bilt and need a ready-to-install spindle assembly. Because the parts are sold as a two-piece set with hardware, it is convenient when rebuilding both sides of a 46' deck or keeping a spare on hand.

It is not intended for users who need custom shafts, nonstandard pulley sizes or heavy-duty commercial mowers; buyers with concerns about long-term durability or those needing a different belt size should check fit and belt dimensions before ordering.

Pros & Cons

• Includes pulley and grease zerk so the spindle is service-ready out of the box.
• Comes with tapped screws and plastic caps, reducing the need to source extra fasteners.
• Perceived as good value for money by many customers compared to buying separate components.

Cons

• Some buyers reported mixed feedback on belt size compatibility, so belt verification may be required.
