117-1192 110-6866 Spindle Assembly Fit for 42" 50" Deck Toro Time Cutter Z4200 Z4202 Z4220 Z4235 Z5020 Riding Mower

What It Is

This is a replacement spindle assembly (OEM part numbers 117-1192 and 110-6866) for the blade drive system on Toro Time Cutter zero-turn mowers. It supports the blade, housing, and pulley, and is a direct wear item that fails when bearings wear out or the housing cracks.

Fitment & Compatibility

• Fits Toro Time Cutter models: Z4200, Z4202, Z4220, Z4235, Z5020 (and variants ending in “Z” or “S”).
• Deck sizes: Works on 42-inch (Z4200 series) and 50-inch (Z5020 series) decks. Do not assume it fits a 54-inch deck—measure your spindle bolt pattern first.
• OEM cross-reference: Replaces Toro 117-1192 and 110-6866; aftermarket version is priced lower than OEM.
• What to measure before buying:
  • Bolt pattern: 3.25 inches center-to-center (verify on your deck).
  • Spindle shaft diameter: 5/8 inch.
  • Pulley mount: 3-bolt pattern with 5/16-18 threads.
• Check your deck serial number—early vs. late production may use different bearings. If in doubt, remove one spindle and compare dimensions.

Key Things to Know

• Quality: Aftermarket version is decent for the price, but OEM bearings last longer in heavy commercial use. Expect 200–400 hours of residential mowing.
• Installation difficulty: Moderate. You’ll need a socket set, torque wrench (pulley nut to 40–50 ft-lbs), and possibly a puller for stuck pulleys. Grease the spindle housing before assembly.
• Common gotchas: The pulley bolt is reverse-threaded on some models—check before cranking. Also, the housing may be slightly taller than OEM; verify blade clearance to the deck if swapping all spindles.
• Warranty: Aftermarket typically has no warranty; OEM carries Toro’s 1-year.

Should You Buy It

If you own a 42" or 50" Toro Time Cutter and need a budget-friendly replacement for a worn spindle, this aftermarket part works well for residential use. For commercial mowers or if you want maximum bearing life, spend extra on the genuine Toro spindle. Measure your bolt pattern first to avoid a return.
