8TEN Deck Rebuild Kit Blade Spindle Belt Idler for MTD Columbia Yard Machines Murray 38 inch CLT38G 942-0610A 918-04474B

What It Is

This is a complete deck rebuild kit for 38-inch MTD-built lawn tractors, including a blade spindle assembly, belt, and idler pulley. It’s designed to replace worn-out deck components on models like the CLT38G, restoring cutting performance and preventing belt slip.

Fitment & Compatibility

• Deck size: 38-inch cutting deck only. Do not use on 42-inch or 46-inch decks.
• Brands/models: Fits MTD, Columbia, Yard Machines, and Murray tractors using the CLT38G deck or similar MTD 38-inch fabricated decks.
• OEM numbers: Replaces 942-0610A (spindle), 918-04474B (belt), and related idler pulley. Cross-check your current part number against these.
• Measurements: Spindle shaft diameter is 5/8-inch; belt is 1/2-inch wide x 92.5-inch length. Measure your old belt and spindle shaft before purchase.
• What to check: Verify your deck model number (stamped on top or side of deck) matches CLT38G. Also confirm you need all three components—some decks may only need one part.

Key Things to Know

• Quality: 8TEN is an aftermarket brand. Users report it’s comparable to OEM for durability, but the belt may wear slightly faster than MTD’s original.
• Installation difficulty: Moderate. Requires basic hand tools (socket set, wrenches) and about 1-2 hours. You’ll need to remove the deck or work underneath the mower.
• Common gotcha: The idler pulley bracket might not align perfectly on all decks—check your old bracket’s bolt pattern before disassembly. Also, the spindle bolt may be reverse-threaded on some models.
• Includes everything? Yes—spindle assembly, belt, and idler pulley. No extra hardware (bolts, washers) are included, so reuse your originals if they’re in good shape.

Should You Buy It

If you have an MTD 38-inch deck and need to replace a worn spindle, belt, or idler, this kit saves time and money over buying parts separately. It’s a solid value for DIY repairs, but if you want maximum belt life or exact OEM fit, stick with MTD-branded parts. Best for owners comfortable with basic mechanical work.
