The JXJKCZ 42-inch mower deck rebuild kit supplies two replacement spindles, two idler pulleys and one belt engineered to fit many MTD, Cub Cadet and Troy-Bilt 42" decks so you can restore cutting performance without replacing the whole deck.

This complete rebuild kit bundles the core wear parts that most commonly fail on 42-inch lawn mower decks: spindle assemblies, idler pulleys and the drive belt.

The kit also includes parts that replace a wide range of OEM numbers, making it a convenient one-purchase solution for deck maintenance.

How does the kit improve deck performance and longevity?

Worn spindles and stretched belts cause uneven cutting, vibration and poor blade speed. Replacing the spindles, idler pulleys and belt restores proper blade alignment and tension so the deck runs smoother and cuts more evenly.

• New spindles renew blade shafts and bearings for reduced wobble and vibration.
• Fresh idler pulleys ensure correct belt tracking and tensioning under load.
• The replacement belt restores correct power transfer from engine to blade spindles.
• OEM cross-fit parts minimize fitment issues during installation.

What’s included and what should I inspect during installation?

The kit contains two spindle assemblies, two idler pulleys and one deck drive belt. While installing, inspect spindle mounting bolts, belt guides and blade condition to determine if additional parts are needed.

• Included: 2 spindles (replaces 918-04822/04889 variants), 2 pulleys (replaces 756-04129 variants), 1 belt (replaces 754-04060A).
