3 Pack 1001046 Spindle Assembly Replaces Murray 492574ma Spindle Assembly 092574MA 094129MA 090905MA for Murray Many 46'' 52'' Lawn Tractors

What It Is

This is a 3-pack of replacement spindle assemblies for 46-inch and 52-inch Murray lawn tractor decks. Spindles mount the blade to the deck and house the bearings that let the blade spin freely; if your deck vibrates, cuts unevenly, or makes grinding noises, a bad spindle is often the cause.

Fitment & Compatibility

Before buying, confirm your deck size (46” or 52”) and check your old spindle’s part number. This set replaces Murray/OEM numbers 492574MA, 092574MA, 094129MA, and 090905MA. Measure the spindle shaft diameter (typically 5/8” or 3/4”) and the bolt pattern on the deck mounting plate—these are designed for Murray’s standard three-bolt pattern. Not compatible with Craftsman, Husqvarna, or MTD decks unless they share the same Murray spindle design. Always verify by comparing the pulley size and blade-mount shape.

Key Things to Know

• Quality variance: These are aftermarket spindles; some users report bearings lasting 1-2 seasons under heavy use. OEM Murray spindles may last longer but cost 2-3x more.
• Installation difficulty: Moderate. You’ll need a socket set, a jack to lift the deck, and possibly a puller to remove the old pulley. Plan 45-60 minutes per spindle.
• Common gotcha: The included grease fittings are pre-installed, but the spindles ship dry. Grease them thoroughly before mounting to extend bearing life.
• Fitment nuance: Some 52” Murray decks use a slightly taller spindle housing—measure the height of your old spindle (typically 4.5” to 5”). If yours is taller, this set may not match.

Should You Buy It

If you’ve got a 46” or 52” Murray lawn tractor with a bad spindle and you’re comfortable with basic deck removal and greasing, this 3-pack is a cost-effective fix. It’s not for heavy commercial use or decks that take a beating daily, but for residential mowing, it’ll get you cutting smooth again without the OEM markup.
