8TEN Deck Spindle for Toro 42 50 inch Timecutter Z4200 Z4220 Z4235 Z5020 Titan ZX5000 110-6866 117-1192

What It Is

The 8TEN Deck Spindle replaces the factory spindle assembly on select Toro TimeCutter and Titan zero-turn mowers. It drives the blade on 42- and 50-inch decks, transferring power from the belt to spin the cutting blade.

Fitment & Compatibility

This spindle fits Toro TimeCutter models Z4200, Z4220, Z4235, Z5020 and Titan ZX5000 with 42- or 50-inch decks. It replaces OEM part numbers 110-6866 and 117-1192.
Before buying:

• Confirm your deck size (42" or 50") – this spindle will not work on 54" or 60" decks.
• Check the spindle housing diameter (typically 1" shaft, 3-bolt pattern).
• Verify your model number on the mower’s ID tag (under seat or on frame).
• This is an aftermarket part, not OEM Toro – compatible but may differ slightly in bearing quality or finish.

Key Things to Know

• Quality vs. OEM: 8TEN uses sealed bearings and a steel housing. It’s a solid budget alternative to Toro’s $50+ OEM spindle. Some users report shorter lifespan under heavy commercial use.
• Installation difficulty: Moderate. Requires removing the deck, belt, blade, and pulley. You’ll need a wrench set, a puller for the pulley, and thread locker for the spindle bolts.
• Common gotcha: The pulley nut may be reverse-threaded on some Toro models – check before forcing. Also, torque spindle bolts to 35-40 ft-lbs; overtightening can warp the housing.
• Bearing noise: A small number of users note slight bearing rumble out of the box. If so, return/exchange immediately. Most run smooth.

Should You Buy It

If you own a Toro TimeCutter or Titan ZX5000 with a 42" or 50" deck and want a reliable, cost-effective replacement for a worn spindle, this is a good pick. It’s best for residential or light commercial use. For heavy-duty daily mowing, stick with the OEM Toro spindle for longer life.
