Youxmoto spindle assembly replacement for 46" mower decks, 2-pack with pulleys & grease zerks - fits Cub Cadet LTX1045/LTX1046

The Youxmoto 918-04865 spindle assembly is a two-piece replacement spindle with pulley and grease zerk built to restore cutting performance on 46" Cub Cadet, MTD, Troy-Bilt and compatible mower decks.

When a worn or damaged spindle causes vibration, poor blade engagement, or uneven cuts, this Youxmoto replacement kit supplies two fully assembled spindles designed to match the fit and function of factory part numbers (918-04865A, 618-04865A, 918-04636, 618-04636, and related references). Each assembly comes with the pulley already installed, grease fitting for maintenance, hardware to mount the units, and protective caps to finish the installation cleanly.

Which mower models and part numbers will these spindles fit?

This kit is built to be compatible with a wide range of LTX and similar 46" decks. It covers numerous Cub Cadet, MTD, Troy-Bilt, Craftsman, Murray and other OEM reference numbers so you can cross-reference existing part codes.

• Fits Cub Cadet models: LTX1045, LTX1046, LTX1046VT, LTX1042 and variants.

How does this spindle assembly install and what comes in the kit?

Each spindle comes preassembled with the pulley and grease zerk, minimizing bench work during replacement. The package includes the fasteners and plastic caps you need to secure and protect the assemblies so you can complete a straightforward swap on the deck.

• 2 x complete spindle assemblies with pulleys installed.
• 8 x tapped mounting screws and 2 x plastic dust caps included.
• Pre-threaded grease fitting (zerk) for easy lubrication after installation.

What are the key dimensions and mechanical features to check before buying?

Confirming a few dimensions ensures the spindles match your deck. The spindle design features the pulley OD and overall height commonly used on 46" LTX decks and mates with a 6-point star spindle shaft found on many machines.

• Overall height approximately 6 6/7" for correct blade-to-deck clearance.
• Pulley outside diameter ~6-1/2" to match belt routing and tension.
• Designed for a 6-point star spindle shaft and standard deck bolt patterns.

How should I maintain these spindles for long service life?

Regular lubrication and inspection keep the assemblies running smoothly and reduce wear. Grease through the provided zerk after a few hours of operation and check mounting hardware for torque and signs of damage seasonally.

• Grease through the zerk after initial break-in and every 10–20 operating hours.
• Inspect pulleys and belts for wear; replace belts if frayed or glazed.
• Retorque mounting screws after first mowing and periodically thereafter.

Who is this for: This Youxmoto 2-piece spindle kit is for homeowners and small-property maintainers who own Cub Cadet LTX-series or similarly configured 46" riding mowers and need a dependable, cost-effective replacement for worn or broken spindles. It's also suitable for technicians and fleet managers who prefer complete, preassembled units—pulley installed and zerk-ready—to reduce repair time and get mowers back in service quickly.
