JYLEYJ 46-inch Mower Deck Rebuild Kit for Cub Cadet MTD Craftsman Troy-Bilt — 2 Spindles, 2 Idlers & Belt

Complete 46-inch mower deck rebuild kit by JYLEYJ that replaces spindles, idler pulleys and belt to restore cutting performance on a wide range of Cub Cadet, Troy-Bilt, Craftsman and MTD lawn tractors.

If your lawn tractor's deck is noisy, uneven or slipping, this kit gathers the most commonly worn deck-drive parts into one service-ready package. It includes two spindle assemblies, two idler pulleys and a replacement deck belt that match OEM numbers used on many 46" decks — reducing parts-sourcing time and helping you get the deck back to reliable cutting quickly. The kit lists multiple OEM cross-references to ensure compatibility with several model families across Cub Cadet, Troy-Bilt, Craftsman and MTD.

Which models and OEM numbers does this kit fit?

This kit is specified to replace commonly worn 46-inch deck components and cites the OEM spindle, idler and belt numbers used by major manufacturers. Cross-references let you confirm fitment for specific tractors before ordering.

• Spindle OEMs: 918-04865A, 918-04636, 918-04636A, 618-04636, 618-04865 series

• Compatible tractors include Cub Cadet LTX1045/LTX1046 families, Troy-Bilt TB2246 and similar Craftsman/MTD models

What parts are included and what do they do?

The kit assembles the essential drivetrain parts that control blade rotation and belt routing on a 46" deck. Replacing worn spindles, idlers and the belt can eliminate vibration, slipping and poor cut quality.

• Two complete spindle assemblies to replace worn bearings/housings and restore blade stability
• Two idler pulleys to maintain correct belt tension and reduce belt damage
• One deck belt matched to OEM sizes for correct routing and length
• Hardware and fit references provided to match your tractor’s mounting layout

How difficult is installation and what tools are needed?

Installation is a medium-difficulty DIY task for mechanically inclined owners or a quick job for any small-engine technician. Basic hand tools and safety precautions are required, and following your tractor’s service manual for torque specs and belt routing is recommended.

• Typical tools: socket set, torque wrench, jack or sturdy blocks to support deck, screwdrivers and pliers
• Allow 1–3 hours depending on experience and whether rusted fasteners are encountered
• Replace hardware if bolts show wear or corrosion and recheck belt alignment after a test run

What maintenance improvements should I expect after replacement?

After installing fresh spindles, idlers and belt, you should notice quieter operation, improved blade tracking and more consistent cutting height and quality. New bearings and pulleys reduce friction and heat, helping the belt last longer.

• Reduced vibration and blade wobble for a cleaner cut
• Improved belt grip and consistent deck speed under load
• Lower risk of belt slipping and premature wear

Who is this for: This JYLEYJ 46-inch deck rebuild kit is aimed at homeowners and pros who maintain Cub Cadet, Troy-Bilt, Craftsman or MTD tractors with 46" decks and need a consolidated parts solution. It’s particularly useful if you’re replacing multiple worn deck components at once or prefer buying a matched set with OEM cross-references to avoid multiple parts orders. If you lack the tools or time, a small-engine service shop can install the kit quickly using the included fitment references.
