8TEN Blade Belt Spindle Kit for MTD Columbia CLT38G Troy Bilt Tuffy Murray M12538 M13538 38 inch 942-0610A 954-04062

What It Is

This is a complete blade belt spindle assembly for 38-inch MTD-built lawn tractors. It replaces a worn or noisy spindle that drives the mower deck blades, restoring smooth cutting performance.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Your mower must have a 38-inch cutting deck. This spindle will not fit 42-inch or larger decks.
• Model compatibility: Designed for MTD, Columbia, CLT38G, Troy-Bilt Tuffy, and Murray models M12538 and M13538. Check your model number under the seat or on the frame.
• OEM cross-reference: Replaces OEM part numbers 942-0610A and 954-04062. If your mower uses different spindle part numbers, this kit may not fit.
• Measurements: The spindle housing is approximately 4 inches tall with a 5/8-inch shaft diameter. Measure your old spindle height and shaft diameter to confirm.

Key Things to Know

• Quality: 8TEN is an aftermarket brand, not OEM. Most users report it’s durable and well-made, but expect slightly different finish than factory parts.
• Installation difficulty: Moderate. You’ll need basic tools (socket set, wrench, jack or blocks to lift the deck). Plan 30–60 minutes per spindle.
• Common gotcha: The spindle uses a 5/8-inch hex shaft—ensure your blade adapter or blade is compatible. Some blades require a different shaft size.
• What’s included: The kit comes with the spindle assembly, mounting bolts, and dust cap. You may need to reuse your old pulley or buy one separately if it’s worn.

Should You Buy It

Buy this if your 38-inch MTD, Columbia, or Murray deck has a failing spindle (noisy, wobbly, or seized) and you want a reliable aftermarket replacement at a good price. It’s a solid choice for DIY repairs, but skip it if you prefer OEM-only parts or need a spindle for a different deck size.
