117-7268 Spindle Assembly Fit for 42" 50" 54" Mower Deck Toro TimeCutter SS5000 MX3450 SS4200 Exmark Quest E S Series Lawn Mower Replaces OEM 117-0751, 117-7267, 117-7439 121-0751 (3 Pack)

What It Is

This is a 3-pack of spindle assemblies that hold and spin the mower blades on zero-turn mowers. Designed for Toro TimeCutter and Exmark Quest/E-Series models with 42", 50", or 54" decks, it replaces worn bearings or damaged housings that cause blade wobble, vibration, or uneven cutting.

Fitment & Compatibility

Check these before buying:

• Deck size: Fits 42", 50", and 54" decks only—measure your deck width.
• Model match: Compatible with Toro TimeCutter SS5000, MX3450, SS4200; Exmark Quest and E-Series. Verify your model number on the mower’s tag.
• OEM cross-reference: Replaces OEM #117-0751, 117-7267, 117-7439, and 121-0751. If your spindle is a different OEM number, measure shaft diameter (must be 1-inch) and bolt hole spacing (typically 3.25" center-to-center).
• Aftermarket note: This is not genuine Toro, but uses standard bearing sizes—confirm your spindle housing has two bolt holes (not three) and a flat mounting surface.

Key Things to Know

• Quality: 4.6 stars from 25 reviews indicates solid build for the price—expect 2-3 seasons of residential use.
• Installation difficulty: Moderate. You’ll need a socket set, torque wrench (30-40 ft-lbs for mounting bolts), and a puller if the old spindle is seized. New spindles come pre-greased.
• Common gotcha: The 3-pack assumes all three spindles are identical—but some decks use a different spindle for the center blade (check your deck diagram). Also, the pulley nut size is 5/8" or 3/4"—have both sockets ready.
• Warranty: No mention of warranty—treat as a budget option; inspect for smooth rotation and no play before installing.

Should You Buy It

If you have a confirmed compatible Toro or Exmark model and want to replace all three spindles at once for under $60, this is a cost-effective fix for wobbling blades or noisy bearings. Skip it if you need a single replacement or have a different brand deck—measure first to avoid returns.
